Abstract
This is a case report of a colonic lipoma. A 51-year old man was admitted to our hospital complaining of right upper quadrant abdominal pain. Barium enema examination revealed an oval, sharply marginated and smoothly contoured polypoid lesion (24×34 mm) in the descending colon. The contour and conf igulation of the tumor was often altered during examination. The colonoscopy revealed a sessile, ball-like tumor covered by smooth mucosa with normal color, vascular pattern and bridging folds. The tumor showed a “cushion sign” phenomenon, and, was therefore, considered to be a submucosal tumor containing liquid. Radiologically and endoscopically, the tumor was thought to be a cystic lymphangioma of the descending colon and was resected by colonoscopic polypectomy. The removed tumor was measured 29×20 ×18 mm in greatest diameter and consisted of submucosal yellow fat tissues.
