Two of five patients, in the First Department of Surgery, Nagasaki University Hospital, who had colonic lipomas had associated colonic carcinomas. We report a rare case of a 73-year-old man who had two submucosal lipomas, three early carcinomas, multiple adenomas in the right-sided colon and limy bile with gallstones. In the Japanese literature, the characteristic features in the 21 reported cases of colonic lipoma associated with colorectal carcinoma were as follows: (1) These lipomas most frequently occurred in elderly women and appeared as small tumors in the right-sided colon. Intussusception occurred as a complication at a low incidence. (2) Colorectal carcinomas that are close to lipomas are simultaneously diagnosed in the right-sided colon. These data suggest that colorectal carcinoma seems unlikely to be causally related to colonic lipoma.
