 We report a case of differentiated adenocarcinoma of the stomach (advanced type Ⅰ and Ⅱa) mimicking a submucosal tumor. A 71-year-old man underwent upper gastrointestinal radiologic examination three years before, which detected an about 2 cm sized protruding tumor at the posterior wall of the upper body. Subsequent endoscopic biopsy examination showed group Ⅰ. During the follow-up period of three years, three endoscopic biopsies were performed and first two biopsy specimen were diagnosed as group Ⅰ, but the lesion grew rapidly about 8 cm in size and the third biopsy specimen revealed group Ⅴ (tub1). He underwent surgical resection. Pathologic diagnosis was macroscopically type Ⅰ + Ⅱa, 75 mm × 85 mm in size on the fundic gland area, and microscopically tub1 (differentiated adenocarcinoma of the stomach type), se, ly (+), v (-), INFβ, Stage Ⅱ. This case is, we believe, informative to the radiologic, endoscopic and biopsy diagnosis.
