We report 10 carcinomas in 8 patients with regional enteritis. Five of the cancers were in the ileum, 4 in the right colon, and 1 in the rectum. The visualized small bowel cancers appeared as benign strictures in small bowel involved by regional enteritis. Most were poorly differentiated. The colon cancers had a more typical radiographic appearance of malignancy. In some patients with small bowel cancer the malignancy was discovered only on histologic evaluation; the malignant nature of the lesion was not appreciated by radiography or gross examination at surgery.
