Abstract
A 33-year-old man had been suffering from eplgastric discomfort and slight distension since the age of 17. No abnormality had been detected by repeated upper Glx-ray examinations by balium. He was admitted to another hospital because of hematemesis and anal bleeding in August,1996. With a diagnosis of the gastric submucosal tumor, he was referred to the hospital for further examination in October. Gastrointestinal endoscopy revealed a pedunculated submucosal soft tumor on the lesser curvature of the antrum, prolapsing into the duodenum. It was moved back through the pylorus easily. There were no redness or ulcer in the stomach. But the notable flare on the surface of the tumor had been shown when the bleeding occurred two months before admission. Abdominal CT scan demonstrated a fat density mass in the descending part of the duodenum. From these findings the tuomr was suspected to be a gastric lipoma, which was subsequently resected. Histological examination confirmed the diagnosis. Retrospectively, the tumor had been already disclosed in the upper GI series four years before, but it had been overlooked. The gastric lipoma plolapsing into the duodenum might cause gastrointestinal bleeding.
