A 50-year-old man with persistent epigastralgia showed severe submucosal stenosis in the pyloric area by endoscopic examination. A 5-cm extramural cystic mass with subtle capsular thickening was visualized on CT at the greater curvature of the gastric antrum, whereas nearly complete obstruction was seen on fluoroscopic contrast radiographs. Either ectopic pancreatitis or cancer was considered as a preoperative diagnosis. Postoperative histopathological study verified adenocarcinoma arising from ectopic pancreas tissue in the gastric antrum.
