RESUMO

BACKGROUND: Documentation of lingual tumors is scarce in nonhuman primates. METHODS: Through a multi-institutional retrospective study we compile cases of primary and metastatic neoplasia in non-human primates. RESULTS: We describe five cases of lingual neoplasia. Three cases are primary lingual tumors: chondro-osteoblastic lipoma in a howler monkey, squamous cell carcinoma, and fibroma in two baboons. We describe two cases of metastatic lymphoma in the tongue in rhesus macaques. A literature review of published lingual neoplasia in nonhuman primates is included in this manuscript. CONCLUSION: Lingual neoplasia is seldom reported in non-human primates.

RESUMO

Osteolipoma is a rare benign variant of lipoma and constitutes less than 1% of all lipomas, presenting as a well-circumscribed painless mass. It is a tumor known to occur in several regions, usually intraosseous or adjacent to bone tissue, whose pathogenesis is still unclear. Imaging exams are useful in their evaluation and, mainly, in surgical planning, which consists of tumor excision. However, the definitive diagnosis of osteolipoma is made by histopathological examination. Although benign, osteolipomas can compress surrounding structures, leading to important symptomatology, as in this case reported in which it is in contact with the brachial plexus.

RESUMO

A doença de Madelung é caracterizada pelo acúmulo simétrico e difuso de tecido adiposo com crescimento tumoral lento e progressivo. Neste relato de caso, um paciente portador dessa síndrome foi atendido no Hospital das Clínicas, em Recife, PE, com o objetivo de realizar uma redução do conteúdo lipomatoso através de lipectomia. O paciente apresentava volumosas massas de tecido adiposo elástico ao redor do pescoço e região supraclavicular e a proposta terapêutica consistiu em uma cirurgia em dois tempos, com lipoaspiração e lipectomia cervical anterior, seguida de lipoaspiração e lipectomia cervical posterior. Antes da cirurgia, foi solicitado um parecer cardiológico, que indicou um risco intermediário, mas não contraindicou o procedimento. Após 4 dias da cirurgia, o paciente apresentou equimoses e edema periférico na ferida operatória cervical, porém estava assintomático. As técnicas de lipectomia e lipoaspiração são consideradas os métodos de tratamento mais eficazes para a doença de Madelung. No entanto, a escolha da cirurgia deve ser baseada em uma avaliação abrangente da gravidade da doença, localização da massa e expectativas do paciente, uma vez que ambas as técnicas possuem vantagens e desvantagens.

Madelung's disease is characterized by the symmetric and diffuse accumulation of adipose tissue with slow and progressive tumor growth. In this case report, a patient with this syndrome was treated at Hospital das Clínicas, in Recife, PE, to reduce the lipomatous content through a lipectomy. The patient presented large masses of elastic adipose tissue around the neck and supraclavicular region and the therapeutic proposal consisted of a two-stage surgery, with liposuction and anterior cervical lipectomy, followed by liposuction and posterior cervical lipectomy. Before surgery, a cardiological opinion was requested, which indicated an intermediate risk but did not contraindicate the procedure. Four days after surgery, the patient presented bruises and peripheral edema in the cervical surgical wound but was asymptomatic. Lipectomy and liposuction techniques are considered the most effective treatment methods for Madelung disease. However, the choice of surgery should be based on a comprehensive assessment of the severity of the disease, location of the mass, and patient expectations, as both techniques have advantages and disadvantages.

RESUMO

Cord lipomas are frequent findings in laparoscopic inguinal hernia surgeries in male patients. The symptoms of lipoma and the potential benefits of removing them are often overlooked because the focus is on the primary pathology of the hernia itself. Current recommendations are to reduce this fatty content, when present. When inguinal cord lipomas are left untreated in inguinal hernia surgery they can potentially cause symptoms and be detected in follow-up imaging exams. The objective of this study was to study incidence of cord lipomas in a cohort operated on by a single group specializing in abdominal wall surgery, as well as to analyze the possible relationship of this finding with the patient's symptoms, the characteristics of the operated hernia and postoperative outcome. This is a prospective study of male patients operated on for inguinal hernia laparoscopically or robotically in a single reference center. Of the total of 141 hernias, the distribution according to European Hernia Society classification showed that 45.4% were lateral, 19.1% medial and 35.5% mixed, highlighting a variety in the presentation of hernias. Analysis of the size of the hernias revealed that the majority (35.5%) were ≤ 1.5 cm. Inguinal cord lipoma was present in 64.5% of the samples, with no statistically significant association between the presence of the lipoma and an indirect hernia sac or obesity. The incidence of surgical site occurrences (SSO) was 9,2%, with seroma and hematoma. No recurrences were observed during follow-up, indicating a successful approach. There were no statistically significant relationships between SSO, the presence of lipoma and indirect hernial sac.

RESUMO

Introdução: os lipomas são as neoplasias benignas de origem mesenquimal mais comum, podendo acometer diversas partes do corpo, sendo a região maxilofacial, de fato, uma das menos frequentes. Clinicamente, manifestam-se como aumentos de volume de crescimento lento e circunscrito, de base séssil ou pediculada, superfície lisa e consistência macia e coloração amarelada. Os sítios intra-orais mais acometidos são a mucosa jugal e o vestíbulo bucal.Dentre suas variantes microscópicas mais comuns, estão o fibrolipoma, composto de um componente fibroso. No entanto, tais variações não afetam o prognóstico do seu tratamento, que deve ser realizado através da excisão conservadora da lesão. OBJETIVO: O presente trabalho tem como objetivo relatar um caso atípico de lipoma intra-oral. DESCRIÇÃO DO CASO: Paciente do sexo feminino, 67 anos, apresentou-se com aumento de volume em região de fundo de vestíbulo mandibular com evolução de, aproximadamente, 10 meses, indolor, com queixas de dificuldade no posicionamento da prótese dentária inferior. O diagnóstico inicial foi de lipoma, confirmado por análise anatomopatológica através de biópsia excisional da peça. Considerações finais: O tratamento de lipomas intra-orais preconizado pela literatura é a excisão local, obtida por meio da biópsia excisional, sendo uma solução eficaz e de baixa morbidade ao paciente(AU)

Introduction: lipomas are the most common benign neoplasms of mesenchymal origin, which can affect different parts of the body, with the maxillofacial region, in fact, one of the least frequent. Clinically, they manifest as slow-growing, circumscribed swellings, with a sessile or pedunculated base, smooth surface, soft consistency and yellowish color. The most affected intraoral sites are the buccal mucosa and the buccal vestibule. Among its most common microscopic variants are the fibrolipoma, composed of a fibrous component. However, such variations do not affect the prognosis of its treatment, which must be carried out through conservative excision of the lesion. OBJECTIVE: This study aims to report an atypical case of intraoral lipoma. CASE DESCRIPTION: A 67-yearold female patient presented with swelling in the bottom region of the mandibular vestibule with an evolution of approximately 10 months, painless, with complaints of difficulty in positioning the lower dental prosthesis. The initial diagnosis was lipoma, confirmed by anatomopathological analysis through excisional biopsy of the specimen. Final considerations: The treatment of intraoral lipomas recommended by the literature is local excision, obtained through excisional biopsy, being an effective solution with low morbidity for the patient(AU)

RESUMO

The finding of a lipoma in the middle ear is much rarer than its occurrence in the external auditory canal or even the inner ear, with fewer than seven cases described in the literature and none of them in Spain or South America. Despite its benign nature, the location of the lipoma may compromise structures that play a significant role in auditory preservation or balance control, necessitating surgical removal as a curative treatment. The main objective of this article is to describe the presentation of lipomas in the middle ear as a possible, although rare, etiology to consider in patients presenting with hearing loss, instability, or both symptoms concurrently, seeking otorhinolaryngological evaluation.

El hallazgo de un lipoma en el oído medio es mucho más raro que su ocurrencia en el canal auditivo externo o incluso en el oído interno, con menos de siete casos descritos en la literatura y ninguno de ellos en España o Sudamérica. A pesar de su naturaleza benigna, la ubicación del lipoma puede comprometer estructuras que desempeñan un papel significativo en la preservación auditiva o en el control del equilibrio, lo que hace necesaria la extirpación quirúrgica como tratamiento curativo. El objetivo principal de este artículo es describir la presentación de los lipomas en el oído medio como una posible, aunque rara, etiología a considerar en pacientes que presentan pérdida de audición, inestabilidad o ambos síntomas simultáneamente, buscando evaluación otorrinolaringológica.

Resumo O osteolipoma é uma rara variante benigna do lipoma e constitui menos de 1% de todos os lipomas, se apresentando como uma massa indolor bem circunscrita. É um tumor conhecido por ocorrer em várias regiões, comumente intraósseas ou adjacente ao tecido ósseo, cuja patogênese ainda não está clara. Os exames de imagem são úteis em sua avaliação e, principalmente, no planejamento cirúrgico, que consiste na exérese tumoral. Contudo, o diagnóstico definitivo do osteolipoma é realizado pelo exame histopatológico. Apesar de benigno, o osteolipoma pode comprimir estruturas ao seu redor, levando a importante sintomatologia como neste caso relatado em que está em contato com o plexo braquial.

RESUMO

Resumen Los tumores de estirpe lipomatosa son lesiones frecuentes en los tejidos blandos, principalmente en el tejido celular subcutáneo y ocasionalmente en zonas más profundas. Los lipomas, tumores de estirpe benigna, son los más frecuentes y representan el 50% de todos los tumores de partes blandas. Se componen de tejido adiposo maduro y presentan características de imagen típicas en resonancia magnética (RM). Sin embargo, cuando estos tumores mesenquimales presentan elementos desdiferenciados y la apariencia de estos no presenta hallazgos típicos de un lipoma ni tampoco de un liposarcoma, se consideran dentro del grupo de tumores lipomatosos "atípicos", neoplasias que suelen presentar un curso relativamente benigno cuando se presentan en las extremidades en comparación con sus homólogos retroperitoneales. Estos tipos de tumores no suelen metastatizar, sin embargo, tienen altas tasas de recurrencia local y un potencial de desdiferenciación tardía en sarcomas de mayor grado con potencial de metástasis. Por otro lado, los liposarcomas, menos frecuentes, se distinguen por su localización en planos más profundos y presentan una apariencia diferente en la RM, con masas que muestran intensidad grasa, septos irregulares y áreas no adiposas. Destacaremos, mediante revisión de la bibliografía, la utilidad de la RM en la identificación y diferenciación de las lesiones de estirpe lipomatosa.

Abstract Lipomatous lineage tumors are common lesions in soft tissues, primarily in subcutaneous tissue and occasionally in deeper areas. Lipomas, benign tumors, are the most common and represent 50% of all soft tissue tumors. They consist of mature adipose tissue and exhibit typical imaging characteristics on magnetic resonance imaging (MRI). However, when these mesenchymal tumors present dedifferentiated elements and their appearance does not show typical findings of either a lipoma or a liposarcoma, they are considered within the group of "atypical" lipomatous tumors, neoplasms that often have a relatively benign course when occurring in the extremities compared to their retroperitoneal counterparts. These types of tumors do not usually metastasize; however, they have high rates of local recurrence and a potential for late dedifferentiation into higher-grade sarcomas with metastatic potential. On the other hand, liposarcomas, less common, are distinguished by their location in deeper planes and have a different appearance on MRI, with masses showing fatty intensity, irregular septa, and non-adipose areas. We will highlight, through literature review, the utility of MRI in the identification and differentiation of lipomatous lineage lesions.

RESUMO

RESUMEN Se presenta un caso de bronquitis aguda confundido como neumonía de la comunidad en Emergencias Médicas con un lipoma pre existente de pericardio. Se realizan consideraciones sobre los lipomas en tomografías, incidencia y diagnósticos diferenciales, así como su confusión por profesionales no avezados en imágenes.

ABSTRACT We present a case of acute bronchitis misdiagnosed as community-acquired pneumonia in Medical Emergencies with a pre-existing pericardial lipoma. Considerations are made regarding lipomas in tomography, their incidence, and diffe rential diagnoses, as well as the confusion that can arise among professionals who are not well-versed in imaging.

RESUMO

We report the case of a giant lipoma of the quadrigeminal cistern in a 30-year-old female patient with headache, nausea, vomiting, and phono and photophobia. Despite the large size of the tumor, conservative treatment was chosen. Intracranial lipomas are rare benign tumors commonly associated with congenital anomalies, and their origin is related to an incorrect embryonic development. The diagnosis is made mainly by cranial computed tomographyand magnetic resonance imaging. The treatment of lipoma can be surgical or conservative, and there is no single treatment for the different patients' cases.

Relatamos o caso de um lipoma gigante de cisterna quadrigeminal em uma paciente de 30 anos, do sexo feminino, com cefaleia, náusea, fono e fotofobia, no qual se optou pelo tratamento conservador. Os lipomas intracranianos são tumores benignos raros comumente associados a anomalias congênitas, e sua origem relaciona-se ao mau desenvolvimento embrionário. A investigação diagnóstica é feita predominantemente através da tomografia computadorizada e ressonância nuclear magnética do crânio, e não existe um tratamento único para os diferentes quadros dos pacientes.

RESUMO

Abstract Lipomas are the most common soft-tissue tumors in the human body, but their location in the hand is rare. Symptomatic hand lipomas, due to nerve compression, are even rarer. We present a case of median nerve neuropathy as a result of a giant palm lipoma, located on the thenar and hypothenar areas of the hand. The patient had typical symptoms of carpal tunnel syndrome, along with compromised thumb motion. Intraoperatively, the recurrent motor branch of the median nerve was sitting on the lipoma under a great tension. This particular location of the motor branch of the median nerve in relation to the lipoma makes this case unique. The tumor was excised protecting the neurovascular structures, and a few weeks later the patient regained full thumb motion, grip strength, and resolution of dysesthesia.

Resumo Os lipomas são os tumores de partes moles mais comuns no corpo humano, mas sua localização na mão é rara. Os lipomas de mão que causam sintomas por compressão do nervo são ainda mais raros. Apresentamos um caso de neuropatia do nervo mediano decorrente de um lipoma palmar gigante, localizado nas regiões tenar e hipotenar da mão. A paciente apresentava sintomas típicos de síndrome do túnel do carpo, além de comprometimento dos movimentos do polegar. Durante a cirurgia, o ramo motor recorrente do nervo mediano repousava sobre o lipoma sob grande tensão. Esta localização particular do ramo motor do nervo mediano em relação ao lipoma torna este caso único. O tumor foi extirpado, protegendo as estruturas neurovasculares e, poucas semanas depois, a paciente havia recuperado totalmente os movimentos do polegar e força de preensão, além de apresentar resolução da disestesia.

RESUMO

Objetivo: Descrever um caso de paciente com lipoma oral intramuscular e compilar os principais aspectos dessa rara lesão. Relato do caso: Mulher caucasiana de 78 anos queixou-se de inchaço na língua. O aumento de volume apresentava cerca de 5 anos de evolução. O exame físico revelou uma lesão nodular na borda lateral direita da língua com diâmetro de aproximadamente 2,5 cm, macia ao toque, superfície lisa sem indícios de trauma, coloração semelhante à da mucosa lingual e com limites nítidos. Realizou-se biópsia excisional e o exame histopatológico revelou tecido adiposo maduro, com fibras musculares aprisionadas no interior e ao redor da lesão, ausência de atipias citológicas e mitoses, estabelecendo o diagnóstico definitivo de lipoma intramuscular. Não houve recorrência durante um período de 4 anos. Discussão: Lipoma é uma neoplasia benigna composta por adipócitos maduros, incomum na cavidade oral. Seu padrão intramuscular é uma forma rara de lipoma com comportamento infiltrativo e taxa de recorrência maior que o lipoma comum. Sua etiopatogenia não é totalmente compreendida e seu tratamento padrão é a excisão cirúrgica. Essa lesão faz diagnóstico diferencial com outras patologias importantes, inclusive o lipossarcoma. Existem poucos casos documentados de lipomas intramusculares em língua. Conclusão: O lipoma oral intramuscular é raro e o cirurgião-dentista precisa atentar ao seu diagnóstico diferencial com lipossarcoma e ao seu maior potencial de recidiva em relação ao lipoma comum.

Aim:To describe a case of a patient with intramuscular oral lipoma and to compile the main aspects of this rare lesion. Case report:A 78-year-old caucasian woman complained of a swelling on her tongue. The increase in volume showed an evolution of about 5 years. Physical examination revealed a nodular lesion on the right lateral border of the tongue with a diameter of approximately 2.5 cm, soft to the touch, smoothsurface with no evidence of trauma, color similar to that of the lingual mucosa and with clear limits.An excisional biopsy was performed and the histopathological examination revealed mature adipose tissue, with muscle fibers trapped inside and around the lesion, absence of cytological atypia and mitosis, establishing the definitive diagnosis of intramuscular lipoma. There was no recurrence over a period of 4 years. Discussion:Lipoma is a benign neoplasm composed of mature adipocytes, uncommon in the oral cavity. Its intramuscular pattern is a rare form of lipoma with infiltrative behavior and a higher recurrence rate than the common lipoma. Its etiopathogenesis is not fully understood and its standard treatment is surgical excision. This lesion makes a differential diagnosis with other important pathologies, including liposarcoma. There are few documented cases of intramuscular lipomas on the tongue. Conclusion:Intramuscular oral lipoma is rare and dentists need to pay attention to its differential diagnosis with liposarcoma and its greater potential for recurrence in relation to common lipoma.

RESUMO

Colonic lipomas are benign tumors originating in mesenchymal tissue and are considered the second most common benign tumor in the colon after adenomatous polyps. They tend to affect women more; their most frequent location is the right colon. Generally, these lipomas do not exhibit symptoms, but when they reach a considerable size, they can cause manifestations. They can also result in complications such as obstruction, intussusception, and perforation. Since their radiological characteristics are similar to fat, they can be visualized using computed tomography. Still, the final diagnosis is made through colonoscopy, where a fatty mass with an oval shape and elastic capacity is observed. Lesions can be removed endoscopically or surgically. Spontaneous expulsion of a lipoma rectally is rare, and its mechanism is not yet fully understood. Although the literature establishes a cut-off point of 2 cm to decide between endoscopic or laparoscopic resection, the former is increasing and can extend this limit. Surgical resection is recommended in cases such as the one in this article. This case is the biggest reported colonic lipoma (13 cm) expelled spontaneously.

Los lipomas colónicos son tumores benignos que se originan en el tejido mesenquimal y se consideran el segundo tumor benigno más común en el colon, después de los pólipos adenomatosos. Tienden a afectar más a mujeres y su localización más frecuente es el colon derecho. Por lo general, estos lipomas no presentan síntomas, pero cuando alcanzan un tamaño considerable pueden causar manifestaciones. También pueden dar lugar a complicaciones como obstrucción, intususcepción y perforación. Dado que sus características radiológicas son similares a la grasa, pueden ser visualizados mediante tomografía computarizada, aunque el diagnóstico definitivo se realiza mediante colonoscopia, donde se observa una masa grasa con forma ovalada y capacidad elástica. Las lesiones pueden ser extirpadas endoscópicamente o quirúrgicamente. La expulsión espontánea de un lipoma por vía rectal es rara y su mecanismo aún no está completamente comprendido. Aunque la literatura establece un punto de corte de 2 cm para decidir entre resección endoscópica o laparoscópica, la primera está en aumento y puede ampliar este límite. En casos grandes, como el reportado en este artículo, se recomienda una resección quirúrgica. Este caso particular se destaca por ser el lipoma de colon más grande reportado hasta ahora (13 cm) expulsado espontáneamente.

RESUMO

El lipoma retroperitoneal puro es un tumor benigno del tejido mesenquimatoso. Su aparición en la región retroperitoneal es rara, frecuente en adultos. Se han propuesto varias teorías, como la alteración del metabolismo de la glucosa, la terapia hormonal y la siembra después de la resección de un fibroma. Se presenta un caso de una mujer de 45 años con presencia de dolor abdominal en región de hipogastrio, fosa iliaca derecha y flanco derecho. La TC abdomino pélvica, revela una gran masa que contenía componente graso en retroperitoneo. Paciente fue sometido a laparotomía y mediante la técnica de apertura tras peritoneal de Cattell-Brasch se accede a retroperitoneo y se visualiza tumor lipoma toso de 20 x 20 cm. aproximadamente se realiza exéresis de la misma de manera exitosa, cursa con evolución favorable hasta su alta hospitalaria. Se confirma el diagnostico de masa lipoma tosa.

RESUMO

Resumen La intususcepción en el adulto es una entidad clínica quirúrgica extremadamente rara, su etiología principal en esta población se atribuye generalmente a origen maligno, la patología benigna es de menor frecuencia y presenta un reto para el diagnóstico prequirúrgico, puesto que su presentación es inespecífica y variable. A continuación, se presenta un caso clínico que debuta con un cuadro clínico de dolor en hipocondrio derecho intermitente, manifestando agudización y resultados de estudios de laboratorio inespecíficos, por lo que inicialmente se pensó que la razón del dolor era una patología de origen biliar y, por ende, se realizó una ecografía de hígado y vías biliares, con lo que observaron signos sugestivos de intususcepción secundaria a un lipoma, por lo que se realizó una tomografía de abdomen simple que corroboró el diagnóstico.

Abstract Intussusception in adults is an extremely rare surgical clinical entity, its main etiology in this population is generally attributed to malignant origin, benign pathology is less frequent and presents a challenge for pre-surgical diagnosis, since its presentation is non-specific and variable. Below is a clinical case that debuted with a clinical picture of intermittent pain in the right upper quadrant, manifesting exacerbation and non-specific laboratory tests, for which initially pathology of biliary origin was thought to be the reason for the pain, and therefore, an ultrasound of the liver and bile ducts was performed, observing signs suggestive of intussusception secondary to a lipoma, for which a simple abdominal tomography was performed to corroborate the diagnosis.

RESUMO

Hibernomas are uncommon and benign tumors made up of brown fat cells. These tumors are typically found in the thigh, axillae, shoulder, back, neck, thorax, arm, and retroperitoneum. There are 4 histological variants of hibernomas, including the typical pattern, myxoid, lipoma-like, and spindle cell variant. The lipoma-like variant is characterized by numerous univacuolated adipocytic cells with intermingled multivacuolated granular cells. It is worth noting that lipoma-like hibernoma in the breast is infrequent. In this case, we present a 72-year-old woman with a history of moderately differentiated cholangiocarcinoma, obesity, and no family history of breast cancer. She consulted for a mass sensation in her right breast that had been present for a year. The mass was not painful and showed no inflammation or nipple discharge. Upon physical examination, a palpable 14 cm mass was identified, occupying the 2 internal quadrants and causing deformation of the surface of the right breast. Imaging studies indicated a solid mass in the lower-inner quadrant of the right breast, which was oval-shaped, well-defined, and displayed internal vascularization. Initially, a diagnosis of low-grade liposarcoma was considered, leading to a core needle biopsy guided by ultrasound. However, the histopathology study revealed a lipoma-like hibernoma, an exceedingly rare benign lesion. Lipoma-like hibernoma can present as a palpable mass or may be incidentally discovered. It should be considered in the differential diagnosis of any lesion containing fatty content. Imaging methods may suggest its presence, but histopathology confirms the diagnosis and its accuracy prevents needless overtreatment.

RESUMO

Although lipomas are the most common mesenchymal tumors, the intramuscular type is rare. We report the case of a patient with rotator cuff arthropathy with a lipoma in the teres minor. Wide surgical excision and total shoulder arthroplasty with reverse prosthesis was performed and 18 months of follow up showed excellent results with any recurrence. The teres minor is extremely important for the proper function of a reverse prosthesis, and lipoma growth in the muscular belly can compromise the functionality of the prosthesis. To the best of our knowledge, this is the first case report of a rotator cuff arthropathy with a lipoma in the teres minor.

RESUMO

We present the case of a 56-year-old male patient with a history of atrial flutter for six months; he was admitted to the hospital for presenting a mass of 8 cm in maximum diameter in the right atrium, which prolapsed through the tricuspid valve into the right ventricle. Emergency surgery was scheduled, performing exeresis of the tumor and tricuspid annuloplasty. The Pathological anatomy determined that the removed mass corresponded to a cardiac lipoma.

RESUMO

Lipomas can occur anywhere in the body where fat cells are present; however, intraosseous lipomas are rare. Although solitary lesions have already been reported in the gnathic bones, to the best of our knowledge, this is the first case of bilateral intraosseous lipoma. A 62-year-old woman was referred for evaluation of a swelling on both maxillary tuberosities. The radiographic examination showed a mixed radiolucent-radiopaque image with ill-defined borders on the right side of the maxilla, and an ill-defined radiolucency on the left side. Histologically, both sides revealed numerous mature adipocytes surrounded by immature bone and dystrophic calcification. The patient remains under follow-up and free of disease for 8 months. Due to the rarity of the intraosseous lipomas in the jaws, a literature review of the published cases was performed jointly with this unique case report.
