A CASE OF DEPRESSED TYPE EARLY DUODENAL CANCER

Abstract

A 48-year-old man had been followed up in our hospital because of duodenal ulcer. Follow-up endoscopy and hypotonic duodenography showed depressed type tumor with redness and marginal elevation, measuring 7X7mm in size, at the third portion of the duodenum. The histological examination of the biopsy specimens highly suggested well differentiated adenocarcinoma, and endoscopic mucosal resection was performed. But perforation was encountered and a pancreatico-duodenectomy was performed. The resected specimen showed type IIc+IIa early duodenal cancer. Histological examination showed well differentiated adenocarcinoma with low-grade atypia restricted to the mucosa. The authors reviewed 16 cases of depressed type early duodenal cancer in Japanese literature.
