RESUMO
Angioleiomioma (AL) é um tumor benigno de origem perivascular que raramente é observado na cavidade oral, principalmente em localizações como a gengiva. Devido sua apresentação clínica inespecífica, os ALs podem mimetizar outras lesões orais, como tumores benignos de glândulas salivares e lesões reacionais, como o granuloma piogênico. O presente artigo objetiva relatar um caso raro de AL localizado em gengiva, em uma paciente de 19 anos. Clinicamente, a lesão apresentava-se como um tumor assintomático, oval, pedunculado, bem definido, com superfície lisa, consistência fibrosa e cor eritematosa, semelhante a um granuloma piogênico, Uma biópsia excisional foi realizada e o fragmento foi encaminhado para análise histopatológica, que revelou uma proliferação vascular de diversos calibres, contendo paredes musculares espessas e proliferação muscular adjacente, além de infiltrado inflamatório, predominantemente crônico, hemácias extravasadas e área de ulceração, consistente com o diagnóstico de AL inflamado. A histopatologia desempenha um papel importante no diagnóstico final de lesões raras e com características clínicas inespecíficas. A excisão cirúrgica da lesão é o tratamento de escolha mais eficaz para os ALs orais. (AU)
Angioleiomyoma (AL) is a benign tumor of smooth muscle of perivascular origin that is rarely seen in the oral cavity, mainly in locations like the gingiva. Due to their nonspecific clinical presentation, ALs can mimic other oral lesions, such as benign salivary gland tumors and reactional lesions, as a pyogenic granuloma. We reported a case of an AL located in the gingiva in a 19-year-old female patient. In clinical terms, the lesion was presented as an asymptomatic, oval, pedunculated, well-defined nodule with a smooth surface, fibrous consistency and erythematous color, similar to a pyogenic granuloma. An excisional biopsy was performed and the fragment was sent for histopathological analysis that revealed a vascular proliferation of different calibers, containing thick muscle walls and adjacent muscle proliferation, in addition to an inflammatory infiltrate, predominantly chronic, extravasated red blood cells and an area of ulceration, consistent with the diagnosis of inflamed AL. The histopathology plays an important role in the final diagnosis of rare lesions and with nonspecific clinical characteristics. The surgical excision of the lesion is the most effective treatment of choice for oral ALs. (AU)

Objective: To report a case of pleomorphic adenoma that was surgically removed and to describe the surgical technique available to remove this lesion. Case Report: A male patient, caucasian, 46 years old, with a 4-year history of pleomorphic adenoma. He mentioned that he went to other services for treatment, but without success. He came at our service for treatment with tumoral excision. Local anesthesia was performed with mepivacaine with a vasoconstrictor and tumoral excision was performed with the overlying mucosa and the periosteal region to avoid recurrence. The patient has been under postoperative follow-up for two years without recurrence. Conclusion: Pleomorphic adenoma is a benign tumor and presents as a submucosal mass of slow growth. The ideal treatment for the Pleomorphic Adenoma tumor is the total excision of the lesion with the removal of the mucosa covering the region to avoid recurrence. (AU)

Resumen Los hamartomas quísticos retrorrectales (tailgut cyst) son tumores congénitos multiloculados, poco frecuentes y derivados de remanentes embrionarios posanales que a menudo no se diagnostican debido a su rara incidencia, localización anatómica y su presentación clínica inespecífica. Presentamos el caso de un paciente de 21 años con historia de fístula perianal que fue intervenida, pero presentó recidiva y en la resonancia se encontró el hamartoma quístico. El tratamiento definitivo fue la resección completa de la lesión por vía posterior (Kraske-Mason).
Abstract Retrorectal Cystic Hamartoma (tailgut cyst [TGC]) are uncommon, multiloculated congenital tumors derived from embryonic post-anal or tail gut remnants often undiagnosed due to their rare incidence, anatomical location, and non-specific clinical presentation. We presented a 21-year-old patient with a perianal fistula history who underwent surgery. Nonetheless, she showed recurrence, and the cystic hamartoma was found in the resonance imaging. Therefore, the definitive treatment was complete resection of the lesion by posterior approach (Kraske-Mason).

Se describe el caso clínico de una paciente de 32 años de edad, con antecedentes de esquizofrenia paranoide, atendida en la consulta de Ortopedia y Traumatología del Hospital General Docente Dr. Juan Bruno Zayas Alfonso de Santiago de Cuba, por presentar aumento de volumen en la cara interna del muslo izquierdo que le dificultaba la marcha. Al examen físico se observó un tumor de aproximadamente 20 cm, no doloroso a la palpación, así como blando y pastoso, con límites imprecisos y adherido a planos profundos. Según los estudios imagenológicos efectuados se trataba de tejido graso, por lo que no existía correlación con los elementos aportados al examen físico. Teniendo en cuenta lo anterior se discutió el caso con los imagenólogos y se decidió realizar la exéresis del tumor. Se tomó muestra para biopsia cuyo resultado informó la presencia de un hibernoma. La fémina evolucionó satisfactoriamente y se reincorporó a sus actividades habituales a los 2 meses.
The case report of a 32 years patient with history of paranoid schizophrenia is described. She was assisted in the Orthopedics and Traumatology Service of Dr. Juan Bruno Zayas Alfonso Teaching General Hospital in Santiago de Cuba, due to an increase of volume in the internal face of the left thigh that difficulted her from walking. A tumor of approximately 20 cm was observed with the physical exam, that was not painful to the palpation, but soft and doughy, with imprecise limits and adhered to deep planes. According to the imaging studies it was an adipose tissue, reason why there was no correlation with the elements obtained with the physical exam. Taking into account the above-mentioned the case was discussed with the imaging specialists and the decision was removing the tumor. A sample for biopsy was taken whose result informed the presence of a lipoma. The woman had a favorable clinical course and she returned to her usual activities 2 months later.

RESUMO
Introducción: El linfangioma quístico es un tumor benigno infrecuente del sistema linfático que afecta habitualmente a los infantes. La opción terapéutica ideal es la extirpación quirúrgica. Objetivo: Sistematizar contenidos esenciales relacionados con el diagnóstico y tratamiento del linfangioma quístico. Métodos: Se realizó la búsqueda y el análisis de la información en un período de 10 años (2010-2020). Se emplearon las palabras clave: "linfangioma quístico" y "malformación linfática congénita quística", en español e inglés. Se hizo la revisión bibliográfica en un total de 62 artículos publicados en las bases de datos y bibliotecas electrónicas científicas de la salud: PubMed, Google Académico, Pubmed, Medline, Biblioteca Virtual en Salud, LILACS y SciELO, mediante el gestor de búsqueda y administrador de referencias EndNote; de ellos se seleccionaron 50 relevantes para el objetivo de la revisión. Resultados: La información se estructuró en los siguientes aspectos: sinonimia y antecedentes históricos, epidemiología, clasificación, patogenia, bases esenciales para el diagnóstico, tratamiento, complicaciones y pronóstico. Se identificaron controversias en cuanto a la terapéutica, y se mostraron las imágenes de los infantes diagnosticados y tratados por la autora en su colaboración médica en Angola en 2018. Conclusiones: Se sistematizan las bases esenciales para el diagnóstico y tratamiento del linfangioma quístico para que el cirujano general que, en su desempeño profesional, brinda asistencia médico quirúrgica a infantes fuera de Cuba, se empodere de las especificidades de este tumor linfático. También se revela como factible su resección quirúrgica íntegra para evitar recidivas, discapacidad y mejorar la calidad de vida del afectado(AU)
Introduction: Cystic lymphangioma is a rare benign tumor of the lymphatic system that usually affects infants. The ideal therapeutic option is surgical removal. Objective: Systematize essential contents related to the diagnosis and treatment of cystic lymphangioma. Methods: The search and analysis of information was carried out over a period of 10 years (2010-2020). The keywords "cystic lymphangioma" and "cystic congenital lymphatic malformation" were used in Spanish and English. The bibliographical review was carried out in a total of 62 articles published in the databases and electronic scientific health libraries: PubMed, Google Scholar, Pubmed, Medline, Virtual Library in Health, LILACS and SciELO, through the search and reference manager called EndNote; of these, 50 that were important to the objective of the review were selected. Results: The information was structured in the following aspects: synonym and historical backgrounds, epidemiology, classification, pathogenesis, essential bases for diagnosis, treatment, complications and prognosis. Therapeutic disputes were identified, and images of infants diagnosed and treated by the author in her medical collaboration in Angola in 2018 were shown. Conclusions: The essential bases for the diagnosis and treatment of cystic lymphangioma are systematized, so that the general surgeon who, in his-her professional performance, provides surgical medical assistance to infants outside Cuba is informed on the specificities of this lymphatic tumor. Its full surgical resection is also revealed as feasible to prevent recurrence, disability and to improve the quality of life of the affected person(AU)

ABSTRACT BACKGROUND: Tumor protein p63 (p63) has been reported to be highly expressed in giant cell tumor of bone (GCTB). Whether p63 can be treated as a diagnostic marker for GCTB remains unclear. OBJECTIVE: We conducted a meta-analysis to evaluate the applicability of p63 in diagnosing GCTB. DESIGN AND SETTING: Systematic review and meta-analysis carried out in a public hospital, Hong Kong, China. METHODS: We searched PubMed, EMBASE and the Cochrane Library from inception to April 30, 2019. Literature in English or Chinese about the differential diagnosis of GCTB using p63 were included. Animal experiments, reviews, correspondence, case reports, expert opinions and editorials were excluded. Studies were also excluded if they did not provide sufficient information to construct a 2 × 2 contingency table. We calculated individual and pooled sensitivities and specificities. We used I² as an indicator of heterogeneity. RESULTS: Out of 88 records identified, 8 articles on 788 GCTB patients fulfilled the inclusion criteria and were included in the present analysis. Bivariate analyses yielded a pooled mean sensitivity of 0.87 (95% confidence interval, CI, 0.72-0.95) and specificity of 0.71 (95% CI, 0.56-0.82) for using p63 as a biomarker in diagnosing GCTB. The area under the receiver operating characteristic curve was 0.86 (95% CI, 0.82-0.88). CONCLUSION: p63 is a helpful indicator in diagnosing GCTB due to its high sensitivity and specificity. Nonetheless, the results need to be carefully interpreted based on other diagnostic methods such as imaging. SYSTEMATIC REVIEW REGISTRATION: 164115 (PROSPERO registration number)

Resumo O hemangioma de coroide é um tumor benigno relativamente raro, que se apresenta de forma circunscrita ou difusa, sendo esta última normalmente associada à Síndrome de Sturge-Weber. Os tumores circunscritos manifestam-se de forma insidiosa, com o diagnóstico realizado comumente após o aparecimento de sintomas secundários. Apresentam como diagnóstico diferencial lesões graves e potencialmente letais, como melanoma de coroide e doença metastática. Neste relato descrevemos o caso de um hemangioma intraocular nodular avançado associado a descolamento hemorrágico da retina, evidenciando o desafio do diagnóstico diferencial devido às semelhanças clínicas e radiológicas compartilhadas pelos tumores.
Abstract Choroidal hemangioma is a fairly rare benign vascular tumor that can manifest in either circumscribed or diffuse type; the latter one is usually related to Sturge-Weber Syndrome. The circumscribed tumors have an insidious presentation and diagnosis is commonly made after the onset of secondary symptoms. Serious and potentially lethal lesions, such as choroidal melanoma and metastatic disease, may represent a differential diagnosis. In this report, we describe an advanced case of nodular hemangioma associated with hemorrhagic retinal detachment. This case highlights the challenge of differential diagnosis in intraocular tumors, due to their similar clinical and radiologic features.

RESUMEN El poromaecrino es un tumor benigno de la glándula sudorípara, compuesto por células que se diferencian de la porción intraepidérmica del conducto excretor. Representa el 10% de los tumores de glándulas sudoríparas. Estos tumores no tienen una morfología característica, lo que puede dificultar al diagnóstico clínico. La localización más frecuente es en palmas, plantas y generalmente es de aparición solitaria.
SUMMARY Eccrineporoma is a benign tumor of the sweat gland composed of cells, that differ from the intraepidermal portion of the excretory duct. It represents 10% of the sweat gland tumors. These tumors do not have a characteristic morphology, which can make clinical diagnosis difficult. The most frequent localization is in palms and plants and is usually of solitary appearance.
RESUMO
Resumen Introducción: los leiomiomas esofágicos son tumores benignos, que son resecados por enucleación esofágica cuando son mayores de 5 cm o en lesiones de cualquier tamaño que sean sintomáticos o sospechosos de malignidad. Tradicionalmente, se ha realizado la resección por técnica de enucleación abierta; sin embargo, la cirugía mínimamente invasiva ha surgido como una técnica con grandes ventajas y, en especial, la tecnología robótica parece ofrecer ventajas. Caso clínico: se reporta un caso de leiomioma esofágico del esófago medio con enucleación mediante el uso de una técnica toracoscópica asistida por robot. La esofagoscopia intraoperatoria y la transiluminación fueron complementos útiles para identificar el esófago y desarrollar un plano de disección extramucosa seguro, que junto con la asistencia robótica parecen minimizar los riesgos intraoperatorios, entre ellos, potencialmente la probabilidad de lesión mucosa, y mejoran el tiempo de recuperación postoperatoria.
Abstract Introduction: Esophageal leiomyomas are benign tumors which are resected by esophageal enucleation when they are symptomatic, suspected of malignancy, or larger than 5 cm. Traditional resection uses the open enucleation technique, but minimally invasive surgery has emerged as a technique that has great advantages, especially when combined with robotic technology. Case report: We report a case of leiomyoma of the middle esophagus with treated with enucleation using a robotic-assisted thoracoscopic technique. Intraoperative esophagoscopy and transillumination were useful for identifying the esophagus and developing a plan of safe extra mucosal dissection. Together with robotic assistance this seems to minimize intraoperative risks including that of mucosal injury while also improving postoperative recovery time.

INTRODUCTION: The nasopharyngeal angiofibroma (NA) is a benign tumor that originates from the pterygopalatine fossa and extends to the adjacent anatomical structures and affects frequently young individuals. The basic treatment for NA is surgical resection, but in some cases the tumor is surgically inaccessible. CASE PRESENTATION: We describe the case of a 45-year-old male with respiratory difficulty after the appearance of a soft palate lesion. The clinical appearance of NA was not specific. DISCUSSION: There are still discussions about the best therapeutic strategy and controversies about performing incisional biopsy. To our knowledge, this is the first report of a NA in an adult patient in which the general health conditions prevented the therapeutic approach, besides the extension of the lesion and its complications. CONCLUSION: Our case shows that NA may reach high proportions and its involvement in older patients should be considered. In this report, we showed the limitation of the therapeutic strategy for advanced cases of NA.
RESUMO
Abstract The present study is a case report of vulvar lipoma. The vulva is a rare site for the development of lipomas, and the aim of the study is to determine if the current imaging modalities can diagnose lipomas correctly. A 43-year-old patient presented with a painless, slowly progressive, oval, mobile and non-tender right vulvar mass compressing the vagina and totally covering the introitus. Both the ultrasonography and magnetic resonance imaging (MRI) exams suggested the diagnosis of lipoma. Surgical excision was performed, and the histopathological examination of the mass confirmed a lipoma.

An odontoma is a mixed benign odontogenic tumor, being a hamartomatous neoplastic lesion of odontogenic epithelial and mesenchymal cells that form enamel, dentine and cement, which occurs in the second to third decade of life, and is commonly a radiographic finding. The aim of this paper is to describe the management of a compound odontoma with guided bone regeneration. A 20-year-old asymptomatic male patient with no relevant surgical medical history underwent surgery for the enucleation of a compound odontoma followed by guided bone regeneration of the defect, and histopathological study of the specimen. The evolution was favorable, without any sign of recurrence. It is important to carry out a previous surgical plan, taking into account the size of the defect resulting from its enucleation, assess the need for guided bone regeneration and use complementary diagnostic resources for a satisfactory recovery.
