Colonic Lipomas and Liposarcomas

Gastro-intestinal lipomas are benign rare adipose tissue tumors, most frequently seen in the submucosal layer of the colon. They are often small and asymptomatic although larger tumors may become symptomatic and pose a diagnostic challenge. Colonoscopy is reliable for the diagnosis of a typical lipoma, but the endoscopic appearances may be worrisome especially when the lesion is atypical, ulcerated or bleeding. CT and MRI Imaging may reveal the signal and uptake of adipose tissue but a confident diagnosis may not be possible.
