Lipomatosis intestinal múltiple: informe de un caso / Multiple intestinal lipomatosis: case report

Introducción: La lipomatosis intestinal es una rara enfermedad con una incidencia en autopsias de 0.04 a 4.5 %. Pocos casos se han informado en la literatura médica. La condición es por lo general asintomática. Los casos sintomáticos se presentan con obstrucción o, con menor frecuencia, hemorragia. Los estudios con bario, ultrasonografía y tomografía computarizada son los procedimientos diagnósticos más comunes. Caso clínico: Hombre de 51 años de edad evaluado por dolor abdominal progresivo, taquicardia, cefalea y náusea. Fue estudiado un año antes por hemorragia gastrointestinal sin diagnóstico definitivo. La tomografía computarizada de abdomen con contraste demostró múltiples masas submucosas en estómago e intestino delgado. Las características del estudio con bario y tomografía computarizada fueron típicas de lipomatosis, por lo que no se realizaron procedimientos invasivos o quirúrgicos. El paciente se ha mantenido asintomático por un año. Conclusiones: Los tumores benignos del intestino delgado son relativamente raros, siendo el lipoma el tipo más común. El caso informado es inusual debido a la afección de estómago, duodeno, yeyuno e íleon. Los lipomas por lo general se presentan con superficie lisa y defectos de llenado no ulcerados. Con los hallazgos radiológicos típicos es posible hacer el diagnóstico preoperatorio si se considera esta rara enfermedad.

BACKGROUND: Intestinal lipomatosis is a rare disease with an incidence at autopsy ranging from 0.04 to 4.5%. Few cases have been reported in the medical literature. The condition is usually asymptomatic. Symptomatic cases usually present as obstruction or, less frequently, as bleeding. Intestinal barium studies, ultrasonography and computed tomography (CT) are useful diagnostic techniques. CLINICAL CASE: A 51-year-old male was evaluated for progressive abdominal pain, tachycardia, headache and nausea. One year before this examination, he was evaluated for gastrointestinal bleeding. Abdominal CT with contrast enhancement demonstrated multiple submucosal masses in stomach and small bowel. CT and barium examination features were typical of lipomas. No specific treatment, invasive procedures or surgery were performed for the asymptomatic intestinal lipomas. The patient has remained symptom-free for 1 year. CONCLUSIONS: Benign tumors of the small bowel are relatively rare, with lipoma being the most common type. The case reported here is considered to be unusual because stomach, duodenum, jejunum and ileum were affected. Lipomas are usually seen as smooth, nonulcerated filling defects. With these typical radiographic findings, preoperative diagnosis is possible keeping in mind this rare disease.

A Case of Lipohyperplasia of the Stomach / 대한소화기내시경학회지

Lipohyperplasia is a lesion characterized by diffuse infiltration of lipocyte in the submucosal layer, which was formally known as 'lipomatosis' or 'lipomatous hyperplasia'. Lipohyperplasia is distinguished from lipoma, the former is not encapsulated and has normal mucosa. Most of lipohyperplasia developed at the ileocecal valve, showed clinical manifestation of abdominal pain, rectal bleeding, intestinal intussuception and intestinal obstruction. We experienced a case of a 45-year-old woman who had polypoid lipohyperplasia of the stomach. Her chief complaint was recurrent epigastric discomfort. Endoscopic finding was a 10 9 mm sized polypoid lesion in the anterior wall of lower body of the stomach. Endoscopic polypectomy was performed and the histological examination revealed infiltration of lipocyte in the submucosal layer.

A case of lipohyperplasia of the appendix / 대한내과학회지

Large intestinal Lipohyperplasia (LPH) is a poorly recognized lesion characterized by adipose tissue infiltration in the submucosal layer of the colon. Most of all, LPH developed at Ileoceal valve, especially upper lip which was called by ileocecal valve syndrome. For endoscopists and radiologists, it has often remained difficult to make a distinction from malignant neoplasia. We report here the case of a mild obese, 51-year-old man who had polypoid lipohyperplasia of the colon associated with extreme hyperplasia of the appendix. His chief complaint was recurrent intermittent abdominal pain. The colonoscopic finding was a submucosal tumor-like polypoid mass originating from appendix with smooth surface, But ileocecal valve was intact. Abdominal CT finding was 2.5 cm sized round heterogeneous low density mass like lesion with intratumoral fatty density of cecal tip area with enhancement of peripheral portion. In barium enema study, after retrograde filling of contrast, smooth extrinsic indentation of cecal tip with partial filling of appendix was seen. Histological exemination revealed infiltration of mature adipose tissue in the submucosal layer. Because of recurrent abdominal pain, ileocecal resection was performed at operation. We discuss the case and review the literatures on this subject.
