Abstract
An autopsy case was presented in which the supra-am-pullary duodenal carcinoma coexisted with the sigmoid carcinoma and polyp of the descending colon. A 79-year-old male was admitted to the hospital on march 8, 1974 because of coliky pains in the right upper quadrant abdomen. The upper G-I series showed a filling defect in the second portion of the duodenum. Duodenofiberscopic examination demonstrated an irregular ulcer with the stenotic lumen, and biopsy specimen showed adenocarcinoma. But the patient had already been in so serious condition to undergo surgery and was treated conservatively. He died on Nov. 24, 1974. At the postmortem examination, the supra-ampullary adenocarcinoma of the duodenum was of an ulcerated type and encircled the lumen with the length of 3 cm. In addition, there were found both sigmoid adenocarcinoma which was of a polypoid type with a size of 3.3.1.5cm and the pea-sized pedunculated adenomatous polyp about 10cm oral to the part of the sigmoid cancer. In this case, a combination of duodenof iberscopic examination and a selective biopsy proved the most helpful for diagnosis of the duodenal carcinoma. We also reviewed the literature of coexistence of the duodenal ca with the sigmoid ca.
