A 82 year-old man visited the Tsuruoka Kyoritu Hospital, with the chief complaint of anorexia and epigastric discomfort. Gastrointestinal endoscopy revealed an irregular depressed lesion at the posterior wall of the second portion of the duodenum. Histological examination of the biopsied specimen revealed adenocarcinoma. Pancreaticoduo-denectomy was performed. The resected specimen showed an irregular depressed lesion, measuring 1.4×1.2cm in diameter, located at the posterior wall of the second portion of the duodenum close to the papilla Vater. Histological examination revealed well-differenciated tubular adenocarcinoma confined to the mucosa, with no metastasis to lymph nodes and no vascular invasion. This case was the 45th case of the early duodenal carcinoma, and the 4th case of the depressed type reported ever in Japan.
