점막하종양으로 오인된 호산구성 위염 1예

Abstract

Eosinophilic gastroenteritis is an uncommon disorder characterized by eosinophilic infiltration of the bowel wall, usually associated with peripheral blood eosionphilia. It usually involves the stomach and small intestine simultaneously. If the stomach alone is involved, the lesion can sornetimes be misdiagnosed as a primary gastric neoplasm. We experienced a case of eosionphilic gastritis mistaken for gastric submucosal tumor. A 37-year-old man presented to our hospital with acute epigastric pain. Endoscopy showed gastric submucosal tumor in the antrum of the stomach. Endoscopic ultrasonography(EUS) revealed diffuse thickening of the 3rd and 4th layer of the stomach. The patient underwent gastric surgery under the impression that he had a gastic neoplasm.
