A 56-year-old man undergoing hemodialysis had been regularly examined with endoscopy in another hospital because of gastric adenoma after endoscopic polypectomy. Hypotonic duodenography and endoscopy detected a depressed type tumor with redness and marginal elevation, mesuring 6×4 mm in size, in the second portion of the duodenum. The histological examination of the biopsy specimens disclosed well-differentiated adenocarcinoma. Because of a failed endoscopic mucosal resection, a wedge resection of the duodenum was performed. The resected specimen proved to be a IIc+IIa type early duodenal cancer. Histological examination revealed a well differentiated adenocarcinoma restricted to the mucosal layer, and the resected margins were tumor-free. This case was the 25th case of depressed early duodenal cancer, and the first case in a hemodialysed patient.
