A 7l-year-old man was admitted to our hospital because of cerebral infarction. After admission, occult blood in the stool, anemia, and hypoproteinemia were found. X-ray examination revealed a duodenal tumor. However endoscopic examination revealed a cauliflower-like tumor in the upper part of the stomach prolapsing into the duodenum. A cauliflower-like tumor was seen in the resected stomach. It has two heads, one of which was 3.5×2.5×2 cm in diameter. Histologically, the tumor was diagnosed as a tubular adenoma. Ten cases of gastric tumor, including this one, which developed in the upper part of the stomach and prolapsed into the duodenum have been reported in Japan. Clinical aspects of these cases are discussed in this paper.
