A 39-year-old woman underwent a routine upper gastrointestinal series revealing apolyp on the anterior wall of the gastric fornix. Endoscopic examination revealed a pedunculated poiypoid lesion with a smaath surface like submueosal tumor. When enda-scopic ultrasonography was performed, multiple large and small aechoic areas were detected in the polypoid lesion. Endoscopic resection was performed. Histology of the resected specimen revealed that the tumor (18× 17mm in size) was a spongy tissue withmultiple cystic dilatation composed of proliferation of non-atypical ectopic gland cells inthe suhmucosal layer. Thus the lesion was diagnosed as a gastic hamartomatous polyp. Itwas expected that aechoic areas on endoscopic ultrasonography corresponded to the cysticdilatations. This finding was useful in the diagnosis of gastie hamartomatous polyp.
