Large Colonic Lipoma with Mucosal Ulceration Mimicking Carcinoma

Lipoma gigante de colon como causa de rectorragia intermitente

“…En la colonoscopia nos solemos encontrar esta lesión como una masa que aparece cubierta por mucosa de características normales, pudiendo ser sésiles o pediculados. La principal prueba diagnósti-ca es la colonoscopia, que puede ser incluso terapéutica si se trata de lipomas de pequeño tamaño (3,4). En el resto de pruebas de imagen se visualiza como una masa redondeada, intraluminal, homogénea.…”

Giant Intraperitoneal Lipoma of the Cecum

“…5 Colonic lipomas arise in the submucosa but occasionally extend into the muscularis propria or subserosa. 6 Usually, the lipomas are solitary, but can be multiple. 7 The median age at the time of diagnosis ranges from 50 to 69 years and there are no differences in sex prevalence.…”

An Unusual Diagnosis in a Patient with Suspected Colorectal Cancer

“…Large lipomas can become symptomatic and may mimic clinical features and endoscopic appearance of colonic carcinoma [1][2][3][4] . When lipomas are >2 cm, they may present with abdominal pain, bleeding and/or bowel obstruction, either intermittent or complete, secondary to intussusception or to direct luminal obstruction by the enlarging mass [1,2] . CT may demonstrate a well-circumscribed intraluminal mass with low attenuation consistent with soft (fatty) tissue, and it is particularly useful for identifying large colonic lipomas [2] .…”

“…Most of these tumors are asymptomatic and usually detected incidentally during imaging studies or colonoscopy [2] . Large lipomas can become symptomatic and may mimic clinical features and endoscopic appearance of colonic carcinoma [1][2][3][4] .…”
