RESUMEN
Los leiomiomas son tumores mesenquimatosos benignos que se presentan como la neoplasia uterina más común en mujeres en edad reproductiva. Según su crecimiento, se puede ver comprometido su aporte sanguíneo, ocurriendo cambios degenerativos por la carencia de oxígeno, lo cual le confiere un aspecto atípico que puede generar confusión con el diagnostico. Se describe caso de paciente de 47 años de edad, quien consulta por aumento progresivo de volumen de circunferencia abdominal de 7 meses de evolución, referida a la consulta de ginecología oncológica por gran masa tumoral retrouterina de probable origen ovárico con elevado riesgo de malignidad. Luego de realizar estudios preoperatorios es llevada a quirófano, obteniéndose como diagnóstico definitivo, leiomioma con degeneración hialina e hidrópica focal. Los leiomiomas con cambios degenerativos pueden simular tumores malignos de ovario, por lo cual deben ser considerados como un diagnóstico diferencial antes de intervenciones quirúrgicas por tumores abdominopélvicos de gran tamaño(AU)
Leiomyomas are benign mesenchymal tumors that occur as the most common uterine neoplasm in women of reproductive age. Depending on its growth, its blood supply may be compromised, causing degenerative changes due to lack of oxygen, which gives it an atypical appearance that may cause confusion with the diagnosis. The case of a 47-year-old patient is described, who consults for a progressive increase in the volume of abdominal circumference of 7 months of evolution, referred to the gynecology oncology consultation due to a large retrouterine tumor mass of probable ovarian origin with a high risk of malignancy. After performing preoperative studies, she was taken to the operating room, obtaining as a definitive diagnosis, leiomyoma with hyaline and focal hydropic degeneration. Leiomyomas with degenerative changes can simulate malignant ovarian tumors, which is why they should be considered as a differential diagnosis before surgical interventions for large abdominopelvic tumors(AU)

Objetivos: Gosserrelina é indicada para mulheres com leiomioma, por reduzir o risco associado às complicações clínicas. Este trabalho realizou uma análise de custo-utilidade comparando o uso e o não uso de gosserrelina em pacientes com leiomioma sob a perspectiva do Sistema Único de Saúde. Métodos: Um modelo de árvore de decisão foi estruturado para reproduzir o impacto clínico e econômico do uso de gosserrelina antes da miomectomia, cujo comparador seria o não uso de gosserrelina em pacientes elegíveis. Foram considerados: custos médicos diretos e eventos clínicos como complicações intra-hospitalares e tempo de internação. A razão de custo-utilidade incremental é representada pelo custo incremental da gosserrelina por anos de vida ajustado pela qualidade (QALY). Resultados: Em um cenário em que o acesso à gosserrelina é de 51% das pacientes, o custo incremental foi de R$ 629,08. Pacientes no grupo gosserrelina apresentaram um incremento de 0,0261 no QALY. A razão de custo-utilidade incremental foi de R$ 24.019,26 por QALY, ficando abaixo do limiar adotado pelo Ministério da Saúde. Ao variar o percentual de pacientes que recebem gosserrelina para 80% antes de um procedimento cirúrgico, houve um aumento de QALY para 0,5013, reduzindo custos de complicações e a razão de custo-utilidade incremental para R$ 10.581,07 por QALY. No cenário em que 100% das pacientes utilizam gosserrelina, há um aumento de QALY para 0,8290, reduzindo custos de complicações e a razão de custo-utilidade incremental para R$ 10.288,28 por QALY. Conclusão: O uso de gosserrelina possui custo-utilidade favorável, considerando os parâmetros utilizados nesta modelagem econômica. Quando o acesso à gosserrelina é maior, há um decremento expressivo no custo por QALY.
Objectives: Goserelin is indicated for women with leiomyoma to reduce the risk associated with clinical complications. This study conducted a cost-utility analysis comparing the use and non-use of goserelin in patients with leiomyoma from the perspective of the Brazilian Unified Health System. Methods: A decision tree model was structured to reproduce the clinical and economic impact of using goserelin before myomectomy, compared to not using it in eligible patients. Direct medical costs and clinical events such as in-hospital complications and length of stay were considered. The incremental cost-utility ratio is represented by the incremental cost of goserelin per quality-adjusted life year (QALY). Results: In a scenario where access to goserelin is 51% of patients, the incremental cost was R$ 629.08. Patients in the goserelin group showed an increase of 0.0261 in QALY. The incremental cost-utility ratio was R$ 24,019.26 per QALY, below the threshold adopted by the Ministry of Health. When the percentage of patients receiving goserelin was increased to 80% before surgery, there was an increase in QALY to 0.5013, reducing complication costs and the incremental cost-utility ratio to R$ 10,581.07 per QALY. In the scenario where 100% of patients use goserelin, QALY increased to 0.8290, reducing complication costs and the incremental cost-utility ratio to R$ 10,288.28 per QALY. Conclusions: The use of goserelin has a favorable cost utility, considering the parameters used in this economic modeling. When access to goserelin is higher, there is a significant decrease in the cost per QALY.

La inversión uterina es una patología de presentación rara e infrecuente. Se presenta el caso de una paciente con inversión uterina no puerperal con requerimiento de histerectomía abdominal total. Sin antecedentes de importancia asistió al servicio de urgencias por un cuadro clínico de dolor abdominal de 10 días de evolución asociado a sangrado vaginal abundante con inestabilidad hemodinámica y sensación de masa vaginal. Al examen físico se evidenció una masa sobresaliente del canal vaginal de aspecto necrótico, por lo que se sospechó mioma nascens. Durante la estancia hospitalaria presentó inestabilidad hemodinámica, por lo que fue llevada a histerectomía abdominal de urgencia con hallazgo de inversión uterina. La inversión uterina no puerperal es infrecuente. Es importante realizar un buen diagnóstico clínico apoyado de las imágenes si se encuentran disponibles, la intervención quirúrgica es necesaria y proporciona un buen pronóstico. La histerectomía vaginal no es sencilla en estos casos, por lo que se recomienda la histerectomía abdominal total.
Uterine inversion is a rare and infrequent disease. The case of a patient with a non-puerperal uterine inversion that had to be treated with a total abdominal hysterectomy is presented in this study. With no important history of disease, she attended the emergency department presenting abdominal pain in the last 10 days associated with vaginal bleeding and mass sensation. The physical examination revealed a protruding necrotic-like mass through the vagina, hence the suspicion of a myoma nascens. During her hospital ward stay, she presented hemodynamic instability, urgent abdominal hysterectomy had to be done which revealed uterine inversion. Non-puerperal uterine inversion is infrequent. Precise clinical diagnosis is important supported by diagnostic imaging if available. The surgical intervention is necessary, giving a good prognosis. Vaginal hysterectomy is not easy in this type of cases, therefore total abdominal hysterectomy is recommended.

Se presenta el caso clínico de una fémina de 39 años de edad, quien fue asistida en el Hospital General Docente Guillermo Domínguez López de Puerto Padre, provincia de Las Tunas, por presentar una masa tumoral de aproximadamente 10 cm en el hipogastrio. Luego de realizados el examen clínico y los estudios complementarios pertinentes, se decidió practicar la resección completa del tumor. Durante el procedimiento quirúrgico, se tomó muestra para biopsia cuyo resultado indicó la existencia de un leiomioma simplástico en el espacio de Retzius. La paciente evolucionó satisfactoriamente y egresó de la institución a los 5 días, pero se continuó su seguimiento por consulta externa.
The case report of a 39 years woman is presented, who was assisted in Guillermo Domínguez López Teaching General Hospital from Puerto Padre, Las Tunas province, due to a tumoral mass of around 10 cm in the hypogastrium. After the clinical exam and the pertinent complementary studies, it was decided to practice the complete resection of the tumor. During the surgical procedure, a sample for biopsy was taken which result indicated the existence of a symplastic leiomyoma in the Retzius space. The patient had a favorable clinical course and she was discharged from the institution 5 days later, but continued with follow up in outpatient department.
RESUMEN
O sangramento uterino anormal é diagnóstico sindrômico comum no consultório do ginecologista e pode comprometer substancialmente a qualidade de vida. O objetivo no diagnóstico de sangramento uterino anormal é distinguir pacientes com causas estruturais (anatômicas), como pólipo, adenomiose, leiomioma, malignidade e hiperplasia, de pacientes que apresentam anatomia normal, nas quais o sangramento pode ser devido a alteração dos mecanismos de coagulação, distúrbios ovulatórios, distúrbios primários do endométrio, iatrogenia, ou ter outra causa não classificada. O diagnóstico se inicia a partir de anamnese detalhada e exame físico geral e ginecológico completos, seguidos da solicitação de exames complementares (laboratoriais e de imagem), conforme indicado. O exame de imagem de primeira linha para identificação das causas estruturais inclui a ultrassonografia pélvica. Histerossonografia, histeroscopia, ressonância magnética e amostragem endometrial para exame de anatomia patológica são opções que podem ser incluídas no diagnóstico a depender da necessidade. O objetivo deste artigo é apresentar a relevância dos exames de imagem na investigação das causas de sangramento uterino anormal.
Abnormal uterine bleeding is one of the commonest presenting complaints encountered in a gynecologist's office and may substantially affect quality of life. The aim in the diagnosis of abnormal uterine bleeding is to distinguish women with anatomic causes such as polyp, adenomyosis, leiomyoma, malignancy and hyperplasia from women with normal anatomy where the cause may be coagulopathy, ovulatory disorders, endometrial, iatrogenic and not otherwise classified. Diagnosis begins with a thorough history and physical examination followed by appropriate laboratory and imaging tests as indicated. The primary imaging test for the identification of anatomic causes include ultrasonography. Saline infusion sonohysterography, magnetic resonance, hysteroscopy, endometrial sampling are options that can be included in the diagnosis depending on the need. The aim of this article is to present the relevance of imaging exams in the investigation of the causes of abnormal uterine bleeding.

El leiomioma es un tumor mesenquimal benigno común que puede desarrollarse allí donde haya músculo liso; raro como tumor ovárico primario, su origen aún es controversial. El leiomioma ovárico primario es uno de los tumores benignos más raros del ovario, representa 0,5% a 1% de los tumores benignos y suele observase en mujeres entre 20 y 65 años. Generalmente, son asintomáticos y se les encuentra de forma incidental durante el examen pélvico o la cirugía por otra causa, pero en ocasiones puede manifestarse por dolor abdominal y masa palpable. El diagnóstico definitivo es difícil antes de la extirpación quirúrgica. Debido a que no existen síntomas patognomónicos ni tiene imágenes características, los principales diagnósticos diferenciales incluyen fibroma, tecoma, tumor estromal esclerosante y leiomiosarcoma. La tinción inmunohistoquímica es fundamental para el diagnóstico preciso y debe considerarse en el diagnóstico diferencial de los tumores ováricos de células fusiformes. Se presenta un caso de leiomioma ovárico primario.
Leiomyoma is a common benign mesenchymal tumor that can develop wherever smooth muscle is present; rare as a primary ovarian tumor, its origin is still controversial. Primary ovarian leiomyoma is one of the rarest benign ovarian tumors, accounting for 0.5% 1% of benign tumors and is usually seen in women between 20 and 65 years of age. They are usually asymptomatic and appear incidentally during a pelvic examination or surgery for another cause but can occasionally manifest by abdominal pain and palpable mass. Definitive diagnosis is difficult before surgical removal. Because there are no pathognomonic symptoms and no characteristic imaging, the main differential diagnoses include fibroma, thecoma, sclerosing stromal tumor and leiomyosarcoma. Immunohistochemical staining is essential for accurate diagnosis and should be considered in the differential diagnosis of ovarian spindle cell tumors. A case of primary ovarian leiomyoma is presented.
RESUMEN
RESUMEN Introducción : El leiomiosarcoma uterino es un sarcoma poco frecuente sumamente agresivo, que puede presentar metástasis más frecuentemente a pulmón e hígado. Su pronóstico es malo, siendo la histerectomía total temprana el tratamiento de primera línea Otras alternativas son la quimioterapia con regímenes de doxorrubicina, ifosfamida o gemcitabina, solos o en combinación. Reporte de caso : Presentamos a una mujer peruana de 40 años que fue sometida a histerectomía por sospecha de leiomioma; sin embargo, la patología reveló un diagnóstico final de leiomiosarcoma uterino. No se le pudo notificar debido a la pérdida de seguimiento. Dos años más tarde, volvió a presentar metástasis en muslo, mama, hígado, pulmones y cuero cabelludo. Se le administró Ifosfamida y Doxorubicina cada 21 días durante 3 cursos; sin embargo, debido a la progresión de la enfermedad, se decidió un tratamiento paliativo. Finalmente, falleció dos meses después del tratamiento. Conclusión : Se presenta un caso de leiomiosarcoma uterino con metástasis atípica para promover el diagnóstico precoz y diferenciado de leiomioma, leiomiosarcoma de bajo grado y leiomiosarcoma de alto grado para definir el tratamiento correcto.
ABSTRACT Introduction : Uterine leiomyosarcoma is a rare and highly aggressive sarcoma, which can metastasize most frequently to the lung and liver. Its prognosis is poor, with early total abdominal hysterectomy being the first line treatment. Other alternatives are chemotherapy with regimens of doxorubicin, ifosfamide or gemcitabine, alone or in combination. Case report : We present a 40-year-old Peruvian woman who underwent hysterectomy for suspected leiomyoma; however, pathology revealed a final diagnosis of uterine leiomyosarcoma. She could not be notified due to loss to follow-up. Two years later, she again presented with metastases in the thigh, breast, liver, lungs and scalp. He was given Ifosfamide and Doxorubicin every 21 days for 3 courses, however, due to disease progression, palliative treatment was decided. Finally, he died two months after treatment. Conclusion : A case of uterine leiomyosarcoma with atypical metastasis is presented to promote early and differentiated diagnosis of leiomyoma, low grade leiomyosarcoma and high grade leiomyosarcoma to define the correct treatment.
RESUMEN
Abstract Uterine fibroids are the most common benign gynecologic tumors in women of reproductive age, and ultrasound is the first-line imaging modality for their diagnosis and characterization. The International Federation of Gynecology and Obstetrics developed a system for describing and classifying uterine fibroids uniformly and consistently. An accurate description of fibroids in the ultrasound report is essential for planning surgical treatment and preventing complications. In this article, we review the ultrasound findings of fibroids, detailing the main points to be reported for preoperative evaluation. In addition, we propose a structured, illustrated report template to describe fibroids, based on the critical points for surgical planning.
Resumo Os miomas uterinos são os tumores ginecológicos benignos mais comuns em mulheres em idade reprodutiva, sendo a ultrassonografia a modalidade de imagem de primeira linha para seu diagnóstico e caracterização. A Federação Internacional de Ginecologia e Obstetrícia desenvolveu um sistema para descrever e classificar os miomas uterinos de forma uniforme e consistente. Uma descrição precisa dos miomas no laudo ultrassonográfico é essencial para o planejamento do tratamento cirúrgico e prevenção de complicações. Neste artigo, revisamos os achados ultrassonográficos de miomas, detalhando os principais pontos a serem relatados para avaliação pré-operatória. Além disso, propomos um modelo de relatório estruturado e ilustrado para descrição de miomas, com base nos pontos críticos para o planejamento cirúrgico.
RESUMEN
Resumen ANTECEDENTES: La torsión uterina es una rotación del útero sobre su eje mayor de más de 45°; por lo general sucede en torno del istmo uterino. Los leiomiomas son el factor predisponente más frecuente en úteros no grávidos. OBJETIVO: Reportar el caso de una paciente con torsión uterina cervical y miomatosis de grandes elementos. CASO CLÍNICO: Paciente de 42 años, nuligesta, con antecedente de miomatosis uterina de grandes elementos de 27 x 27 cm. Los síntomas se iniciaron con síndrome doloroso abdominal intenso, tipo cólico, localizado en el hipogastrio y la fosa iliaca. En la exploración física el abdomen se percibió doloroso a la palpación superficial y profunda, con una tumoración cercana a la cicatriz umbilical (25 cm), móvil y dolorosa. En la laparotomía exploradora se encontró líquido peritoneal hemorrágico y se observó una torsión uterina (una vuelta) cerca del cuello del útero, además de un mioma subseroso en la cara posterior, de 27 x 27 cm. El útero, los anexos y las salpinges se advirtieron con datos francos de daño vascular, con áreas de isquemia. Por lo anterior se decidieron la histerectomía total abdominal y la salpingooforectomia bilateral. El informe histopatológico reportó: útero con cambio isquémico extenso panmural, sin evidencia de neoplasia maligna. CONCLUSIONES: El dolor abdominal es el síntoma más común de la torsión uterina que puede variar de leve a agudo. El diagnóstico preoperatorio rápido y preciso de torsión uterina es decisivo y se justifica la intervención quirúrgica de urgencia.
Abstract BACKGROUND: Uterine torsion is a rare entity that is defined as a rotation of the uterus on its major axis of more than 45°, generally occurring at the level of the uterine isthmus. Leiomyomas are the most frequent predisposing factor in non-gravid uterus. OBJECTIVE: Report of a case of a gynecological patient with uterine torsion at the cervical level in a uterus with uterine myomatosis of large elements. CLINICAL CASE: A 42-year-old patient, nulliparous, with a history of uterine myomatosis with large elements of 27 x 27 cm. The symptoms began with intense abdominal pain syndrome, colic type, located in the hypogastrium and the iliac fossa. On physical examination, the abdomen was perceived as painful on superficial and deep palpation, with a mobile and painful tumor close to the umbilical scar (25 cm). In the exploratory laparotomy, hemorrhagic peritoneal fluid was found and a uterine torsion (one turn) was observed near the cervix, as well as a subserous myoma on the posterior face, measuring 27 x 27 cm. The uterus, the annexes and the salpinges were noted with frank data of vascular damage, with areas of ischemia. Therefore, total abdominal hysterectomy and bilateral salpingo-oophorectomy were decided. The histopathological report reported: uterus with extensive panmural ischemic change, without evidence of malignancy. CONCLUSIONS: In uterine torsion, abdominal pain is the most common symptom and can range from mild to severe abdominal symptoms. Therefore, a prompt and accurate preoperative diagnosis of uterine torsion is crucial and urgent surgical intervention is warranted.
RESUMEN
Se ha postulado que más del 70 % de las mujeres antes de la menopausia son diagnosticadas de leiomiomas; de estas un 25 % presentan sintomatología grave. La ecografía es la modalidad de imagen de primera elección para su estudio. Se tiene registros de progresión de leiomiomas a leiomiosarcomas, que conllevan a un mal pronóstico y son responsables de una cuarta parte de las muertes por neoplasias uterinas, con una sobrevida a 5 años que van desde 46-53 %, lo cual incentiva el diagnóstico precoz y eficaz de masas uterinas. El caso reportado es una presentación inusual de un leiomioma de gran tamaño, que por los hallazgos de imagen se reportó como una neoplasia maligna, su aspecto macroscópico totalmente atípico reforzaba la sospecha imagenológica. Solo se pudo determinar el diagnóstico definitivo mediante estudio histopatológico posterior a histerectomía. Las evaluaciones ginecológicas de rutina deben incluir exámenes especializados de imagen pélvica, la ausencia de presentación típica o síntomas característicos de una patología no debe ser motivo para obviar exámenes complementarios que permitan un diagnóstico oportuno y tratamiento eficiente de leiomiomas, incluso en casos de presentaciones inusuales y desafiantes para el diagnóstico, como el que se ha reportado en esta obra.
It has been postulated that more than 70% of premenopausal women are diagnosed with leiomyomas; Of these, 25% have severe symptoms. Ultrasound is the imaging modality of choice for its study. There are reports of progression from leiomyomas to leiomyosarcomas, which leads to a poor prognosis, and is responsible for a quarter of deaths from uterine neoplasms, with a 5-year survival ranging from 46-53%; this should encourage early and effective diagnosis of uterine masses. The reported case is an unusual presentation of a large leiomyoma, which due to its imaging characteristics, was reported as a malignant neoplasm. Its completely atypical macroscopic appearance reinforced the imaging diagnosis suspicion. The definitive diagnosis could only be determined by histopathological study after hysterectomy. Routine gynecological evaluations should include specialized pelvic imaging exams, the absence of a typical presentation or characteristic symptoms of a pathology should not be a reason to obviate ancillary testing that would allow a timely diagnosis and effective treatment of leiomyomas, even in unusual and challenging presentations, such as with the patient in this case report.

Abstract Objective: To evaluate the safety and efficacy of using highly compressible calibrated microspheres in uterine artery embolization (UAE) for the treatment of uterine fibroids. Materials and Methods: This was a prospective multicenter study. Thirty-two women with symptomatic uterine fibroids were selected for UAE between January 2019 and March 2020. The participants completed the Uterine Fibroid Symptom and Quality of Life (UFS-QOL) questionnaire, underwent contrast-enhanced pelvic magnetic resonance imaging (MRI), and were submitted to anti-Müllerian hormone measurement, subsequently undergoing UAE with Embosoft microspheres. After six months, the patients again completed the UFS-QOL questionnaire and underwent pelvic MRI. Results: The most common symptoms were abnormal uterine bleeding (in 81.3% of the cases), pelvic pain (in 81.3%), and compression (in 46.9%). Of the 32 patients evaluated, 12 (37.5%) had anemia due to abnormal uterine bleeding. Thirty patients completed the study. Among those patients, we observed median reductions of 21.4% in uterine volume and 15.9% in dominant fibroid volume. We identified no adverse events that could be attributed to the material itself, although there were events attributed to the UAE procedure in general. Conclusion: For the treatment of uterine fibroids, UAE using Embosoft microspheres shows satisfactory results, providing reductions in uterine and dominant fibroid volumes, with a low rate of adverse events, and improving patient quality of life, as well as demonstrating safety and efficacy.
Resumo Objetivo: Avaliar a eficácia e segurança da embolização da artéria uterina (EAU) com microesferas calibradas de alta compressibilidade no tratamento de miomas uterinos. Materiais e Métodos: Este foi um estudo prospectivo e multicêntrico. Foram selecionadas 32 mulheres com miomas uterinos sintomáticos para EAU de janeiro de 2019 a março de 2020. As participantes preencheram o questionário Uterine Fibroid Symptom and Quality of Life (UFS-QOL), realizaram ressonância magnética (RM) pélvica com contraste e teste para medição dos hormônios antimüllerianos, seguido de embolização de miomas com microesferas Embosoft. Após seis meses, as pacientes novamente preencheram o UFS-QOL e realizaram RM pélvica. Resultados: Os sintomas mais relatados foram sangramento uterino anormal (81,3%), dor pélvica (81,3%) e compressão (46,9%). Doze pacientes (37,5%) apresentaram anemia consequente a sangramento uterino anormal. Nas 30 pacientes que completaram o estudo, observou-se redução mediana de 21,4% no volume uterino e 15,9% no volume do mioma dominante. Não foram identificados eventos adversos possivelmente relacionados ao material utilizado, apenas em relação ao procedimento de EAU. Conclusão: EAU com microesferas Embrosoft mostrou resultados satisfatórios no tratamento de miomas uterinos, com redução dos volumes uterino e do mioma dominante, baixa taxa de eventos adversos e melhora na qualidade de vida, demonstrando segurança e eficácia.
RESUMEN
Abstract Introduction: leiomyomas are benign mesenchymal tumors of smooth muscle origin that can develop in various locations. Urethral leiomyomas are rare, with approximately only 120 cases reported in the literature. These tumors often occur in the third and fourth decades of life but are rare in menopausal patients. In general, treatment involves surgery, only three recurrence reports in the literature. Description: a case report on a 56-year-old woman; the patient had type II diabetes mellitus and chronic high blood pressure, was overweight (body mass index, 27.1 kg/m2), and a smoker. Besides this, the patient presented symptoms of urinary obstruction and had a large urethral leiomyoma. The tumor was completely removed with no associated urethral lesions using a complex, combined abdominalvaginal surgical approach. Discussion: the management and treatment on urethral leiomyomas is challenging and have not been established yet due to the rarity of these tumors.
Resumo Introdução: os leiomiomas são tumores mesenquimais benignos de origem muscular lisa, podendo manifestar-se em diversas localizações. Os leiomiomas uretrais são raros, tendo apenas aproximadamente 120 casos relatados na literatura. São mais comuns na terceira e quarta décadas de vida, sendo raros em pacientes menopausadas. Em geral, são tratados cirurgicamente, com apenas três relatos de recidivas na literatura. Descrição: relato de caso de uma paciente do sexo feminino, 56 anos, portadora de diabetes mellitus do tipo II, hipertensão arterial crônica, sobrepeso (IMC 27,1Kg/m2) e tabagismo. Além disso, com quadro de sintomas obstrutivos urinários e portadora de um grande leiomioma uretral, este que foi completamente removido, através de uma desafiadora abordagem cirúrgica combinada (abdominal e vaginal), sem lesões uretrais associadas. Discussão: os leiomiomas uretrais são tumores raros e seu manejo é desafiador e ainda não foi estabelecido.

El angioleiomioma (AL) es una neoplasia benigna, bien circunscrita y de crecimiento lento, que representa 5% de las neoplasias de tejidos blandos y cuya etiología es desconocida. Se origina del músculo liso, mayormente de las paredes de los vasos sanguíneos; su localización es más frecuente en extremidades, siendo raros en la región de cabeza y cuello, y más aún en cavidad bucal. Histológicamente la lesión se caracteriza por ser un nódulo bien encapsulado con proliferación de fascículos de músculo liso maduro alrededor de la luz de los vasos sanguíneos, cuyas células suelen ser positivas a marcadores de inmunohistoquímica como alfa actina de músculo liso, desmina, HHF35, miosina, calponina y H-caldesmon. El tratamiento actual es la escisión quirúrgica completa con una tasa de recurrencia prácticamente nula. El objetivo es resaltar la importancia del diagnóstico y el manejo correcto de las lesiones intraorales a través de la presentación de un caso clínico de un leiomioma vascular localizado en región nasolabial, además de hacer la revisión de la literatura correspondiente (AU)
The angioleiomyoma (AL) is a benign neoplasm, well circumscribed and slow growing, that represents 5% of the soft tissue neoplasms, whose etiology is unknown. It originates from smooth muscle, mostly from the walls of blood vessels; regarding its location, it more frequently appears in the extremities, being rare in the head and neck region, and even more so in the oral cavity. Histologically, the lesion is characterized by being a well encapsulated nodule with proliferation of mature smooth muscle bundles around the lumen of the blood vessels, whose cells are usually positive for immunohistochemical markers such as alpha smooth muscle actin, desmin, HHF35, myosin, calponin and H-caldesmon. The current treatment is complete surgical excision having zero recurrence rate. The objective of the following article is to educate on the importance of correct diagnosis and management of intraoral lesions through the presentation of a clinical case of a vascular leiomyoma located in the nasolabial region, in addition to reviewing the corresponding literature (AU)

RESUMEN Los tumores benignos de músculo liso son los tumores más frecuentes en el aparato genital femenino. El leiomioma disecante cotiledóneo del útero es una variante rara de leiomioma benigno, que presenta patrones de crecimiento inusuales y comparte algunas características con otras variantes de leiomioma disecante. Tiene un patrón de crecimiento inusual caracterizado por disección intramural dentro del miometrio y con apariencia similar de sus componentes extrauterinos a los cotiledones placentarios. Su aspecto sarcomatoide y carácter inusual dan la impresión de malignidad. El diagnóstico se realiza por los hallazgos histopatológicos característicos de la lesión. Se presenta un caso de leiomioma disecante cotiledóneo del útero.
ABSTRACT Benign smooth muscle tumors are the most common tumors in the female genital tract. Cotyledonoid dissecting leiomyoma of the uterus is a rare variant of benign leiomyoma, which presents unusual growth patterns and shares some features with other variants of dissecting leiomyoma. It has an unusual growth pattern characterized by intramural dissection within the myometrium and with similar appearance of its extrauterine components to placental cotyledons. Its sarcomatoid appearance and unusual character give the impression of malignancy. The diagnosis is made by the characteristic histopathologic findings of the lesion. A case of cotyledonoid dissecting leiomyoma of the uterus is presented.
RESUMEN
Resumen ANTECEDENTES: Los leiomiomas parasitarios son una variante poco común de la miomatosis uterina. Se han identificado en la pared abdominal, intestino delgado, muñón cervical o vaginal, vasos iliacos, ovarios, colon sigmoides y en el omento mayor. OBJETIVO: Reportar un caso clínico de leiomioma parasitario retroperitoneal y revisar la bibliografía al respecto. CASO CLÍNICO: Paciente de 57 años, con diagnóstico de NIC-III y hemorragia uterina anormal. Acudió a consulta debido a una sensación de masa y dolor abdominal, pérdida de peso subjetiva, hiporexia, disfagia y plenitud gástrica de cuatro meses de evolución. En los estudios de extensión se documentó una masa retroperitoneal grande y elevación de los marcadores tumorales Ca 125 y Ca 19-9. La resección de la masa se efectuó mediante laparotomía, con hallazgo histopatológico de mioma parasitario. CONCLUSIÓN: Los leiomiomas parasitarios deben considerarse en el diagnóstico diferencial de pacientes con antecedente de histerectomía o miomectomía, sobre todo en el contexto de la morcelación. El tratamiento consiste en cirugía o inhibidores de la aromatasa y análogos de la hormona liberadora de gonadotropina (leiomiomatosis peritoneal diseminada).
Abstract BACKGORUND: Parasitic leiomyomas are a rare entity, defined as an unusual variant of uterine myomatosis. Have been documented in the abdominal wall, small intestine, cervical or vaginal stump, iliac vessels, ovaries, sigmoid colon, and greater omentum. OBJECTIVE: To report a clinical case of retroperitoneal parasitic leiomyoma and review the literature. CLINICAL CASE: A 57-year-old patient with a diagnosis of CIN-III and secondary abnormal uterine bleeding, who consulted for a sensation of abdominal mass and pain, subjective weight loss, hyporexia, dysphagia and gastric fullness, of four months of evolution. Extension studies document a large retroperitoneal mass and elevation of tumor markers Ca 125 and Ca 19-9. We practice surgical management of her gynecological pathology and resection of the mass by laparotomy, with histopathological finding of myoma. CONCLUSION: Parasitic leiomyomas should be suspected in patients with a detected mass and a history of hysterectomy or myomectomy, especially in the context of morcellation. The treatment of this condition is surgical and, in cases of disseminated peritoneal leiomyomatosis, pharmacological treatments have been used with aromatase inhibitors and gonadotropin-release hormone analogues.

Resumen INTRODUCCIÓN: Un leiomioma con cambios degenerativos poco frecuentes es un desafío diagnóstico difícil de diferenciar de sus homólogos malignos, si se pretende fundamentarlo solo en lo advertido en las imágenes. CASO CLÍNICO: Paciente de 40 años de edad, enviada al servicio de Cirugía de mínima invasión en marzo del 2021 debido al aumento del perímetro abdominal, disminución del apetito y disnea de medianos esfuerzos. El ultrasonido abdomino-pélvico reportó que el útero estaba aumentado de tamaño, con miomas intramurales de medianos elementos. El endometrio heterogéneo. El ovario derecho tenía un quiste complejo, gigante, de 276 mm x 250 mm x 276 mm, con volumen de 10 000 cc. Además, esplenomegalia, hidronefrosis derecha y litiasis renal izquierda. Los marcadores tumorales se reportaron normales. En la cirugía por laparoscopia se observó un tumor que ocupaba toda la cavidad abdominal de 40 x 30 cm, adherido a la pared posterior del útero, con ambos ovarios sin alteraciones, sin líquido libre; se procedió a la histerectomía total. CONCLUSIONES: Los cambios degenerativos en los leiomiomas uterinos pueden distorsionar la estructura habitual del tumor y reflejarla en imágenes típicas de una tumoración quística de ovario; en el estudio inicial esto representa un desafío para el cirujano y debe considerarse parte del diagnóstico diferencial de las masas anexiales. En la paciente del caso, con cirugía de mínima invasión, se consiguió la resección completa de la pieza, a pesar del tamaño aumentado, con menores riesgos de complicaciones en la herida y menos dolor posoperatorio; las incisiones son pequeñas y con desenlaces estéticos favorables y menos días de estancia intrahospitalaria.
Abstract INTRODUCTION: A leiomyoma with rare degenerative changes is a diagnostic challenge difficult to differentiate from its malignant counterparts, if it is intended to be based only on imaging findings. CLINICAL CASE: 40-year-old female patient referred to the Minimally Invasive Surgery service in March 2021 due to increased abdominal perimeter, decreased appetite and dyspnea on medium exertion. Abdomino-pelvic ultrasound reported that the uterus was enlarged, with medium-element intramural fibroids. The endometrium was heterogeneous. The right ovary had a complex, giant cyst, 276 mm x 250 mm x 276 mm, with a volume of 10,000 cc. In addition, splenomegaly, right hydronephrosis and left renal lithiasis. Tumor markers were reported normal. Laparoscopic surgery showed a tumor occupying the entire abdominal cavity measuring 40 x 30 cm and attached to the posterior wall of the uterus, with both ovaries unaltered, with no free fluid; total hysterectomy was performed. CONCLUSIONS: Degenerative changes in uterine leiomyomas can distort the usual tumor structure and reflect it in images typical of an ovarian cystic tumor; in the initial study this represents a challenge for the surgeon and should be considered part of the differential diagnosis of adnexal masses. In the case patient, with minimally invasive surgery, complete resection of the specimen was achieved, despite the increased size, with less risk of wound complications and less postoperative pain; the incisions are small and with favorable esthetic outcomes and fewer days of in-hospital stay.

RESUMEN Introducción: Los tumores pancreáticos en el embarazo son muy raros, el diagnóstico y tratamiento en este grupo de pacientes es complejo. Objetivo: Presentar el primer caso de un leiomioma primario del páncreas en una gestante. Caso clínico: Embarazada de 26 años de edad, sin antecedentes relevantes. Primigesta, que se encontraba cursando la semana 13 de gestación. Durante una evaluación ecográfica de rutina, se le detecta una tumoración en la glándula pancreática. Se remitió a la consulta multidisciplinaria de atención a la materna y en conjunto deciden realizar la interrupción voluntaria del embarazo. Luego la paciente fue remitida a la consulta de la especialidadde Cirugía General. Al recibir a la misma, se quejaba de dolor en epigastrio e hipocondrio izquierdo, además de hipo ocasional. Al examen físico se encontró una tumoración palpable en epigastrio. Se realizaron exámenes analíticos básicos sin encontrarse alteraciones, en los estudios de imagen realizados, ecografía abdominal y tomografía contrastada de abdomen se demostró una tumoración en el cuerpo y cola del páncreas. Se planificó tratamiento quirúrgico electivo, se realizó pancreatectomía distal con esplenectomía, por invasión del estómago, se complementó con gastrectomía subtotal. La paciente evoluciona sin complicaciones. La biopsia informó un tumor mesenquimal benigno primario de páncreas, tipo leiomioma, bien encapsulado. Conclusiones: Se presenta el primer caso de un leiomioma primario del páncreas en una gestante. Los tumores pancreáticos en embarazadas son enfemedades raras, el manejo por un equipo multidisciplinario es la mejor forma de obtener resultados satisfactorios para la paciente.
ABSTRACT Introduction: Pancreatic tumors during pregnancy are very rare, diagnosis and treatment are always difficult. Objective: To present the first case of a primary pancreatic leiomyoma in a pregnant woman. Case report: A 26 years old primiparous pregnant is reported, with no relevant backgrounds. She was in her first trimesters of pregnancy. Diagnosed with a pancreatic tumor during a routine evaluation. She was referred to a multidisciplinary consult, deciding the voluntary interruption of pregnancy, then she is evaluated by the General Surgery specialty clinic for complaining of epigastric pain and hiccup. On physical examination an epigastric tumor was found. Auxiliary exams were normal. Imagenologic studies confirm a tumor in the pancreatic body and tail. Surgical treatment was scheduled, distal pancreatectomy with splenectomy, due to invasion of gastric wall subtotal distal gastrectomy was performed. Patient evolution without complications. Biopsy reported a well capsulated, leiomyoma type, primary mesenchymal pancreatic tumor. Conclusions: The first case of a primary pancreatic leiomyoma in a pregnant woman is presented. Pancreatic tumors during pregnancy are rare. Multidisciplinary approach is the best way to improve results.
RESUMEN
Introducción: Los leiomiomas uterinos son los tumores pélvicos benignos más comunes entre las mujeres. Se estima que 60% de las mujeres llegan a tener miomatosis a lo largo de la vida (1). La necesidad de tratamiento médico y/o quirúrgico es muy importante de evaluar, ya que los fibromas son una fuente importante de morbilidad ginecológica. Objetivos: Describir el caso de un gran mioma uterino con manejo prequirúrgico de análogos de GnRH, analizando los hallazgos obtenidos en el caso según la evidencia actual. Discusión: Se reporta el caso de una mujer de 29 años sin antecedentes mórbidos conocidos, con presencia de una gran masa abdominal, motivo por el cual se realizó una ecotomografía abdominal que evidenció una masa sugerente de un gran mioma uterino subseroso. Se realizó miomectomía vía laparotomía previo tratamiento médico con análogos de GnRH. Actualmente la frecuencia de miomas de gran tamaño es poco frecuente, por lo que se busca discutir el impacto del tratamiento médico previo a la cirugía en mujeres jóvenes. Conclusiones: La experiencia con el uso prequirúrgico de agonistas de GnRH indica una ventaja en el trabajo bien definida y su uso como tratamiento coadyuvante a la cirugía está bien establecido. Sin embargo, se debe tener en cuenta la posibilidad de recurrencia de los miomas
Introduction: Uterine leiomyomas are the most common benign pelvic tumors in women. It is estimated that 60% of women develop myomatosis throughout life (1). The need for medical and / or surgical treatment is very important to assess, since fibroids are an important source of gynecological morbidity. Objectives: To describe the case of a large uterine myoma with presurgical management of GnRH analogues and to summarize updated evidence on their use. Discussion: The case of a 29-year-old woman with no known morbid history is reported, with the presence of a large abdominal mass, which is why an abdominal ultrasound scan was performed, which revealed a mass suggestive of a large subserous uterine myoma. Myomectomy was performed via laparotomy after medical treatment with GnRH analogues. Currently, the frequency of large fibroids is rare, so we seek to discuss the impact of medical treatment prior to surgery in young women. Conclusions: Experience with the presurgical use of GnRH agonists indicates a well-defined treatment advantage and its use as adjunctive treatment to surgery is well established. However, the possibility of recurrence of fibroids should be taken into account

Resumen Introducción: la patología gástrica es excepcionalmente benigna, se registra a nivel mundial un porcentaje de aparición de las mismas del 0,005 %-4 %. Además de lo anterior, suele plantearse como primer diagnóstico diferencial un carcinoma gástrico, por lo que la mayoría de los pacientes termina en un procedimiento quirúrgico mayor. El objetivo de este estudio fue describir una serie de casos registrados en una institución de alta complejidad, así como la revisión de la literatura al respecto del tema. Pacientes y métodos: se realizó la revisión de las bases de datos del servicio de cirugía general de la Clínica Universitaria Colombia y se encontraron 4 tumores gástricos de presentación inusual, de los cuales se hizo revisión de la historia clínica y las imágenes disponibles (diagnósticas y de las piezas de cirugía). Resultados: en la revisión de la base de datos, se encontraron 4 casos, 2 de sexo femenino y 2 de sexo masculino, con una media de edad de 51 años (26-75 años). El 100 % de los pacientes tenía una lesión en la región antral y solo uno de ellos tenía una segunda lesión a nivel prepilórico. La totalidad de los pacientes fue llevada a gastrectomía subtotal con reconstrucción en Y de Roux por abordaje laparoscópico y la media de estancia hospitalaria fue de 3,5 días (2-6 días). Conclusión: para determinar la mejor opción de tratamiento en general en pacientes con lesiones gástricas siempre hay que considerar tanto las características endoscópicas y endosonográficas como las histológicas.
Abstract Introduction: Gastric pathology is exceptionally benign with a percentage of appearance between 0.005% - 4% worldwide. Moreover, gastric carcinoma is often suggested as the first differential diagnosis and for that reason, the outcome for a vast majority of admitted patients is a major surgical procedure. This study aims to describe a series of cases recorded in a high complexity medical institution and to carry out a literature review related to that subject. Patients and Methods: Databases from the general surgery service of the Clínica Universitaria Colombia were reviewed, and four unusual gastric tumors were found. A review of the related medical records and available images (diagnostic images and surgical elements) was performed. Results: After the database review, four cases were found: two female cases and two male cases, with a mean age of 51 years (26-75 years). All the patients had lesions in the antrum area and only one of them has an additional lesion in the prepyloric region. All patients were treated with a laparoscopic subtotal gastrectomy with Roux-en-Y reconstruction and the mean length of hospital stay was 3.5 days (2-6 days). Conclusion: It is required to consider the endoscopic, endosonographic, and histological examinations and their features to determine the best treatment for patients with gastric lesions.

Resumen El angioleiomioma es un tumor benigno perivascular que raramente se localiza en el útero. Se expone el caso de un angioleiomioma de gran tamaño en una mujer de 30 años con sangrado menstrual abundante y masa abdominal palpable. La paciente fue sometida a miomectomía y diagnosticada de angioleiomioma por el estudio histológico. Ante síntomas persistentes, la angiomiomectomía o la histerectomía simple son eficaces.
Abstract Angioleiomyoma is a benign perivascular tumor that is rarely located in the uterus. This paper presents a case of a large angioleiomyoma in a 30-year-old woman with heavy menstrual bleeding and a palpable abdominal mass. The patient underwent myomectomy and was diagnosed with angioleiomyoma by histological examination. For persistent symptoms, angiomyomectomy or simple hysterectomy are effective.
