[Primary carcinoma of the jejunum combined with colon polyp--report of a case].

A 47-year-old female patient with a primary carcinoma of the jejunum combined with colon polyp is presented. Having had an attack of vomiting, she visited our hospital. Oral small intestine radiography revealed a localized stricture with ulceration in the jejunum. Small intestinal endoscopy showed a tumor with an irregular surface and hemorrhagic ulceration. Selective superior mesenteric arteriography revealed a stenosis and deviation of arteries. These findings strongly indicated cancer of the jejunum, and a barium enema study and a colonoscopic examination revealed a polyp in the ascending colon. The resected tumor was histologically diagnosed as a well differentiated adenocarcinoma. CEA-positive cells also were observed. Further, a polypoid lesion in the colon was histologically diagnosed as an adenoma.
