Lipoma de recto prolapsado e incarcerado: caso clínico y análisis de la literatura / Prolapsed and incarcerated rectal lipoma: case report and literature review / Prolapso e encarceramento de lipoma do reto: caso clínico e análise da literatura

Los lipomas colónicos son tumores benignos poco frecuentes, extremadamente raros a nivel rectal. A pesar de ello, ocupan el segundo lugar en frecuencia detrás de los pólipos adenomatosos. Aunque la mayoría de los lipomas colorrectales son asintomáticos y se descubren incidentalmente, en ocasiones pueden ser sintomáticos y determinar complicaciones agudas que requieren tratamiento quirúrgico de urgencia. Estas formas de presentación pueden confundirse con las del cáncer colorrectal, constituyendo un desafío diagnóstico y terapéutico. Presentamos el caso de una paciente que consultó en emergencia por una gran masa dolorosa de aparición aguda a nivel del ano, resultando ser un lipoma rectal prolapsado a través del canal anal.

Colonic lipomas are infrequent benign tumors, extremely rare at the rectum. Nevertheless, they follow in frequency polyp adenomas. Even though most colorectal lipomas are asymptomatic and incidental, they can occasionally be symptomatic and develop acute complications that require urgent surgical treatment. This form of presentation can be confounded with colorectal cancer, therefore impairing diagnosis and treatment. We present the case of a female patient who came to the emergency room with an acute painful mass through the anus, that resulted in a prolapsed rectal lipoma.

Omental lipoma in pediatric age group: clinical presentation, image findings and management

ABSTRACT A 2-year-old female patient, admitted in the emergency room, presented diarrhea for 5 days and bloody stools in the last 24 hours. Physical examination revealed no significant findings. Ultrasound was initially performed, showing an elongated, well delimited and solid mass occupying since right hypocondrium until left iliac fossa, displacing adjacent structures. In sequence, magnetic resonance imaging was performed for confirmation of findings suggestive of omentum lipoma. After 1 week, the surgical resection was performed by videolaparoscopic acess. During 2-year follow-up, there was no sign of recurrence.

Hibernoma intramuscular en el muslo izquierdo de una fémina / Intramuscular lipoma in the left thigh of a woman

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.

Lipoma de bola adiposa de Bichat: un caso atípico / Bichat's fat pad lipoma: an atypical case

Los lipomas son tumores benignos compuestos por adipocitos maduros. Si bien representan la neoplasia más común en el cuerpo humano, su aparición en la región de la cabeza y el cuello es relativamente rara. No muestra predilección por sexo y afecta a individuos en la cuarta década de vida. Clínicamente, puede observarse un aumento de volumen nodular, de consistencia blanda y superficie lisa. Su etiopatogenia aún es desconocida, aunque algunos autores han sugerido factores endócrinos, inflamatorios, hereditarios y traumáticos. El diagnóstico se realiza a través de la evaluación clínica, con la ayuda de pruebas de imagen como la tomografía computarizada y la resonancia magnética. Sin embargo, solo puede ser confirmado mediante análisis histopatológico de la lesión, considerado el examen por excelencia. El tratamiento de los lipomas y todas sus variantes consiste en la extirpación quirúrgica total, con lo cual se disminuye la posibilidad de recidivas, que es rara de por sí. El objetivo de esta publicación es informar un caso clínico de lipoma localizado en la región de la mucosa yugal, con extirpación quirúrgica completa de la lesión de manera ambulatoria (AU)

Lipomas are benign tumors composed of mature adipo- cytes. Although they represent the most common neoplasia in the human body, their occurrence in the head and neck region is relatively rare. Regardless of gender, they affect individu- als from the fourth decade of life on. Clinically, an increase of the nodular volume with softened consistency and smooth surface can be observed. Although its etiopathogenesis is still uncertain, some authors have suggested endocrinal, inflam- matory, hereditary and traumatic factors. The diagnosis is made through clinical evaluation, with the aid of imaging ex- aminations, such as computerized tomography and magnetic resonance. However, it can only be confirmed through the histopathological analysis of the lesion, which is considered the gold standard examination. The treatment of the lipomas and all their variations consists of complete surgical exci- sion, thus diminishing the possibility of recurrence, which in turn is rare. The aim of this publication is to report a clin- ical case of lipoma, located in the jugal mucosa region and treated through complete surgical removal of the lesion on an outpatient basis (AU)

Compressive Neuropathy of the Ulnar Nerve in the Hypothenar Region by Lipoma: Case Report

Lipomas are well-defined tumors of the adipose tissue that often occur in the torso or the extremities of adult patients. These tumors usually develop painlessly and insidiously, but theymay compress adjacent structures. The objective of the present study is to describe the case of a 68-year-old female patient with a giant lipoma located at the hypothenar region, with manifestation of compression of the common palmar digital nerves, the ulnar nerve, andthe abductormuscle of theVfinger. Regarding the symptoms, the patient feltmoderate pain in the hypothenar region, with no Tinel sign, and no changes in the motor function or sensibility of the digits innervated by the ulnar nerve. Lipomasmay present a varied range of histological characteristics, and malignant tumors may be a differential diagnosis. An imaging exammay aid in the diagnosis, which is confirmed by a histopathological study. For the present case, as recommended in the literature, a surgical procedure was performed for the resection of the tumor, which resulted in the control of the symptoms.

Invaginación de colon causado por lipoma / Colon invagination caused by lipoma

Los lipomas del colon ocupan el tercer lugar en frecuencia de aparición de tumores benignos. Estos tumores están formados por tejido adiposo bien diferenciado con un estroma fibroso. La gran mayoría de estos lipomas es asintomática, algunos en raras ocasiones presentan complicaciones de urgencia. El fin de esta publicación es presentar un caso de obstrucción de colon por lipoma. (AU)

Benign colonic lesions are infrequent and account for a low percentage of all colonic tumors. Among the benign tumors, lipomas are third in frequency. They are composed of mature adipose tissue with fibrous stroma. Most of them are asymptomatic but in rare instances, they may present as surgical emergencies. We present one case of colonic obstruction caused by lipomas. (AU)

Lipoma: relato de caso / Lipoma: case report

O lipoma é uma neoplasia benigna mesenquimal de rara ocorrência em cavidade bucal, com maior predileção, principalmente pela mucosa bucal, em indivíduos acima da quarta década de vida. Clinicamente o lipoma se caracteriza por um aumento de volume flácido à palpação, de coloração amarelada ou normal de mucosa, com crescimento lento e geralmente assintomático. Histologicamente o lipoma apresenta presença de tecido adiposo maduro com células adiposas de aparência semelhante à gordura normal adjacente, bem circunscrito e podendo apresentar uma fina cápsula fibrosa. O tratamento do lipoma é cirúrgico e consiste na excisão da lesão. Assim, o objetivo do presente trabalho é relatar dois casos de lipoma em cavidade oral localizados em região de mucosa bucal tratado cirurgicamente. Paciente de 50 anos, sexo feminino, melanoderma, cursando com aumento de volume em região de mucosa bucal esquerda com 05 meses de evolução. Ao exame clínico foi possível avaliar lesão em região de mucosa bucal esquerda de aproximadamente 02 cm de diâmetro, flácido à palpação e coloração normal de mucosa. Foi realizada biopsia excisional sob anestesia local e posterior enucleação da lesão. A paciente evolui com 06 meses de pós-operatório sem evidências clínicas de recidiva da lesão ou complicações associadas. O lipoma é de difícil ocorrência em região intra-oral e mesmo quando tratada de maneira conservadora através da enucleação lesão possui baixas taxas de recidiva(AU)

Lipoma is a benign mesenchymal neoplasm of rare occurrence in the oral cavity, with a higher predilection, mainly by the buccal mucosa, in individuals above the fourth decade of life. Clinically lipoma is characterized by an increase in flaccid volume at palpation, yellowing or normal mucosa, with slow and usually asymptomatic growth. Histologically, lipoma has the presence of mature adipose tissue with adipose cells similar in appearance to adjacent normal fat, well circumscribed and may have a thin fibrous capsule. The treatment of lipoma is surgical and involves the excision of the lesion. Thus, the objective of the present study is to report two cases of lipoma in the oral cavity located in a region of buccal mucosa treated surgically. A 50-year-old female patient, melanoderma, with an increase in volume in the region of the left buccal mucosa with 05 months of evolution. At the clinical examination it was possible to evaluate lesion in the region of the left buccal mucosa of approximately 02 cm in diameter, flaccid to palpation and normal mucosa staining. An excisional biopsy was performed under local anesthesia and subsequent enucleation of the lesion. The patient ev olves at 06 months postoperatively without clinical evidence of recurrence of the lesion or associated complications. Lipoma is difficult to perform in the intra-oral region and even when treated conservatively through the enucleation lesion has low rates of relapse(AU)

Giant frontal lipoma mimicking frontal mucocele / Lipoma frontal gigante mimetizando mucocele frontal

ABSTRACT Lipoma is a usually painless benign adipose tumor. Nevertheless, it can cause compression of adjacent structures, depending on its location. Mucoceles are benign cystic lesions in the frontal-ethmoidal region, caused by chronic obstruction of the paranasal sinus and consequent inflammatory processes. The increase of mucocele diameter caused by inflammation often results in bony degradation and reabsorption, increasing pressure on adjacent structures, including the orbit and the base of the skull, leading to possibly serious consequences. Here we report a case of lipoma mimicking a frontal mucocele, managed surgically at the Ophthalmological Hospital of Anapolis.

RESUMO O lipoma é um tumor do tecido adiposo de caráter benigno, usualmente indolor, porém que pode gerar compressão de estruturas adjacentes, dependendo da sua localização. A mucocele consiste em uma lesão cística de caráter benigno, na região fronto-etmoidal, devido à obstrução crônica dos óstios dos seios paranasais e consequente processo inflamatório. O aumento do diâmetro da mucocele por inflamação muitas vezes causa degradação e reabsorção ósseas, o que pode elevar a pressão em estruturas adjacentes como órbita e base de crânio, causando intercorrências possivelmente graves. Neste estudo relatamos um caso de lipoma simulando mucocele frontal, com propedêutica cirúrgica.

Lipoma obstructivo de laringe / Obstructive laryngeal lipoma

Los lipomas de laringe son tumores benignos de crecimiento lento, pero pueden producir síntomas graves como disnea inspiratoria, apneas del sueño y disfagia. Se describe el caso clínico de un paciente con un lipoma extenso de laringe e hipofaringe que consultó por disfagia y disnea inspiratoria intermitente, y que fue tratado con éxito mediante un abordaje transoral con microscopio asistido con cauterio y láser de CO2. (AU)

Laryngeal lipomas are benign, slow-growing tumors, but they can produce severe symptoms such as inspiratory dyspnea, sleep apnea, and dysphagia. We describe the clinical case of a patient with an extensive lipoma of the larynx and hypopharynx who consulted for dysphagia and intermittent inspiratory dyspnea, and who was successfully treated by a transoral approach with microscope and assisted with cautery and CO2 laser.

Lipoma gástrico: lesión submucosa infrecuente: reporte de dos casos tratados / Unusual gastric submucosal lipoma lesion: report of two cases

El lipoma gástrico (LG), es un tumor benigno raro que representa el 5 % de los lipomas gastrointestinales y menos del 1 % de todos los tumores gástricos. Se localizan habitualmente a nivel de la submucosa y generalmente en la región antral. La endoscopia y la tomografía computarizada son las herramientas diagnósticas más utilizadas en el proceso diagnóstico. Dada su relativa rareza, quedan a menudo fuera del diagnóstico diferencial de las masas submucosas gastrointestinales superiores. El objetivo de este manuscrito, es reportar dos casos tratados de forma consecutiva y revisar la literatura existente en esta materia. Se trata de dos pacientes de sexo masculino, de 49 y 69 años de edad, a quienes se diagnosticó una lesión submucosa gástrica por endoscopia y fueron tratados quirúrgicamente y cuyos especímenes fueron estudiados histológicamente, concluyéndose en ambos casos la existencia de un LG. Ambos pacientes evolucionaron de forma correcta y permanecen en controles clínicos y endoscópicos hasta la actualidad, sin inconvenientes. El LG es una entidad poco común, que puede simular una enfermedad maligna. Presentamos dos casos tratados quirúrgicamente con resultados satisfactorios.

Gastric lipoma (GL), is a rare benign tumor that represents 5 % of gastrointestinal lipomas and less than 1 % of all gastric tumors. They are usually located at the level of the submucosa and usually in the antral region. Endoscopy and computed tomography are the diagnostic tools most used in the diagnostic process. Given their relative rarity, they are often left out of the differential diagnosis of the upper gastrointestinal submucosal masses. The aim of this manuscript was to report two cases treated consecutively and review the existing literature on this subject. Two male patients, 49 and 69 years of age, were diagnosed with a gastric submucosal lesion by endoscopy and were treated surgically. The specimens were studied histologically; concluding the existence of a GL in both cases. The two patients evolved adequately and have remained in clinical and endoscopic controls until now, without problems. GL is a rare entity, which can simulate a malignant disease. We present two cases treated surgically with satisfactory results.

Vulvar lipoma: A case report

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.

Mammary hibernoma: A case report of a rare disease / Hibernomamamário: relato de caso de uma doença rara

Abstract Mammary hibernomas are extremely rare benign tumors composed of brown fat cells, with only five cases previously reported in the literature. We report the case of a 42- year-old female patient with a painless growing mass in her right breast. A partial mastectomy was performed, and the diagnosis of hibernoma was confirmed by the histological features and the immunohistochemical profile. Although hibernoma is a benign tumor, its main differential diagnoses include aggressive lesions, making the accurate diagnosis essential to provide adequate care to the patient.

Resumo Hibernomas mamários são tumores benignos extremamente raros compostos por gordura marrom, com apenas cinco casos previamente relatados na literatura. Relatamos o caso de uma paciente do sexo feminino, de 42 anos de idade, apresentando- se com uma massa indolor em sua mama direita. Realizou-se uma mastectomia parcial e o diagnóstico de hibernomamamário foi confirmado pelo padrãomorfológico e pelo perfil imuno-histoquímico. Embora hibernomas constituamneoplasias benignas, seus principais diagnósticos diferenciais incluem lesões agressivas, sendo o diagnóstico acurado extremamente importante para o correto manejo clínico do paciente.

Exérese de lipoma gigante na Clínica da Família: um relato de caso / Giant lipoma excision in the Family Clinic: a case report / Escisión de lipoma gigante en la Clínica Familiar: reporte de un caso

A realização de procedimentos cirúrgicos na Unidade Básica de Saúde é preconizada e descrita na literatura. No entanto, tal prática vem sendo cada vez menos aplicada na atenção primária. Em um contexto de superlotações de hospitais terciários e consequente inoperação de cirurgias eletivas, é de extrema importância a realização desses procedimentos na Clínica da Família. Nesse trabalho, apresenta-se um caso de um paciente submetido à exérese de lipoma gigante incapacitante, na fossa poplítea esquerda, com 12 anos de evolução e com tentativa frustrada de resolução cirúrgica em um hospital terciário.

The implementation of surgical procedures in the Basic Health Unit is recommended and described in the literature. However, such practice has been less and less applied in primary care. In a context of overcrowding of tertiary hospitals and consequent inoperability of elective surgical procedures it is of utmost importance and resolutivity carrying out these procedures in the Family Clinic/Basic Health Unit. In this article, we present a case of a patient who underwent excision of a crippling giant lipoma in the left popliteal fossa, with 12 years of evolution and unsuccessful attempts of surgical resolution in a tertiary hospital.

Los procedimientos quirúrgicos en la Unidad Básica de Salud se recomiendan y se describen en la literatura. Sin embargo, esta práctica se está convirtiendo en una menor aplicación en atención primaria. En un contexto de hacinamiento en hospitales de tercer nivel de atención y dando como resultado la inoperabilidad de las quirugías menores electivas, es extremadamente importante realizar estos procedimientos en la Clínica de la Familia/Unidad Basica de Salud. En este trabajo, se presenta un caso de un paciente que se submetió a la extirpación de incapacitante lipoma gigante en la fosa poplítea izquierda con 12 años de evolución y frustra resolución quirúrgica en un hospital de tercer nivel.
