COLORECTAL NON-EPITHELIAL TUMORS : AN EXPERIENCE

Abstract

During the period 1976-1985, 16 patients with histologically proven colorectal non-epithelial tumor were experienced at the Third Department of Internal Medicine, Tohoku University Hospital. Eight patients had a colorectal lipoma. A diagnosis of lipoma was made easily by endoscopy in most of the cases of lipoma because they appeared yellowish and soft, while it was difficult to make the diagnosis of lipoma in two cases with a large and hard tumor. It was easy to make the diagnosis in all of 3 patients with colonic lymphagioma because the tumor was soft, wavy and watery, and it was also difficult in all of 3 cases of colorectal leiomyoma, one of them revealed leiomyoma coexisted with tubular adenoma in the same tumor. There were two cases of colorectal lymphoma, diagnosed by endoscopic observation as advanced cancer and amebic colitis, respectively.
