  • Look Inside

 Eleven cases of malignant lymphoma involving the rectum and colon seen at the Juntendo University Hospital between 1977 and 1987 are reported. These cases are consisted of nine ileocecal and four rectal cases. Radiographic findings of colo-rectal lymphoma were divided into protrusive and/or concave types. A small lesion of protrusive type is demonstrated as a polypoid lesion, a middle-sized one submucosal tumor, and a large one as coarse nodular lesion. Concave type has a smooth margin and moderate distensibility of colonic wall. Based on these radiographic findings it is possible to make a differential diagnosis of lymphoma or cancer of the large bowel. Chemotherapy for the lymphoma was effective in reducing tumor or ulceration caused by lymphomatous involvement in three cases.
