Lipoma of the Colorectum : Report of Three Cases
نویسندگان
چکیده
mon benign tumors of the colon. However, colonic lipomas are infrequently encountered in clinical practice. Though some lipomas cause abdominal pain, obstruction, or bleeding, most are asymptomatic. Diagnosis can be made by radiologic or endoscopic examinations. Radiographically, the tumor presents as a smooth radiolucent, intra-luminal, extra-mucosal, sessile or pedunculated mass. Endoscopically, the cushion and tenting signs help to assure the diagnosis. Even with advanced examinations, colonic lipomas remain underemphasized and sometimes misdiagnosed. Three cases with unusual symptoms are reported here to illustrate endoscopic and gross features of colonic lipomas in the rectum, transverse colon and ascending colon.
