A Case of Large Lipoma of the Transverse Colon

Abstract

A 56-year-old woman was admitted to our hospital with a history of right hypochond-ralgia. Physical examination was unremarkable. Barium enema and colonoscopy revealed a hen's egg sized polypoid lesion with a soft and smooth surface in the right transverse colon. The tumor moved freely and showed fatty tissue density at abdominal computed tomography. It was diagnosed as a pedunculated lipoma. Endoscopic polypectomy was unsuccessful because the tumor was too large for safe snaring. A segmental resection was done. The pathologic diagnosis was submucosal lipoma of the transverse colon.
