Abstract

Background
/Alms: There have been only a few endoscopic s0dies of lower intestinal lesions of malignsnt lymphoma. The aims of this study were to classify the ileocolonic 1ymphomas according to the colonoscopic fhgdings and to reveal the dinicopathological relationship according to the classes. Methods: Subjects were 24 cases of ileocolonic lymphomas. We evaluated the clinicopathological features according to their endoscopic fmdings. Results: The chief complaints were abdominal pain, bleeding, and abdomina1 mess, Twenty-six lesions from 22 patients, excluding 2 multiple lymphomatous polyposis, were endoscopically classfled as follows. Fungating (10 lemons), ulcerofungating (7 lesions), inflltrative (5 lesions), ulceroinfiltrative (3 lesions), and ulcerative (1 lesion). The 1ocafim of the lesions was the terminal ileum in 11 lesions, the colon in 10 lesions, and both regions in 5 lesions. Within the 1arge bowel, the cecum was involved most frequently, followed by the ascending colon and the remainder. Most of pathological types were the diffuse large cell and the large cell immunoblastic. There was no relationship between the endoscopic findings and the histologic types. Eight eases were manifested as intussusceptlon. Conclasions: Ileocolonic lymphomas can be classified endoscopically into five types. Among the types, fungating and ulcerofungating types axe the most frequent. (Korean J Gastrointest Eadosc 2001;23:21-27)
