Tarry stool indicates bleeding from diseases in the upper gastrointestinal tract such as peptic ulcers or rupture of varices. A 64-year old man complaining of tarry stool visited a hospital for check-up. Upper and lower gastrointestinal endoscopic examination revealed a submucosal tumor-like protruding lesion at the duodenal bulbus. Obvious bleeding was never seen around this lesion. Because there was a erosion on the polypoid lesion, we considered that the lesion was the source of bleeding. The resected specimen revealed that tumor size was 30×25mm and histological diagnosis was Brunner’s gland hyperplasia. We report a case of duodenal tumor found by tarry stool.
