Few cases of histologically proven pancreatists in gastric aberrant pancreatic tissue have been reported, A 43-year-old man admitted for epigastric pain was found in blood tests to have slight inflammatory change without elevated serum amylase. Endoscopic examination showed a submucosal tumor with central umbilication on the greater curvature of the middle gastric body. Abdominal computed tomography (CT) showed a mass, 10 cm in diameter, with scattered calcification and a cystic lesion accompanied by swollen perigastric lymph nodes. After failing to determine a pathological diagnosis after two attempts at EUS-guided fine needle aspiration, we conducted segmental gastrectomy to severe resective margins, because tumor sized did not rule out malignant gastrointestinal stromal tumor or advanced gastric cancer. Histologically, the tumor was diagnosed as aberrant pancreas with acute pancreatitis located between the submucosa and muscularis propria.
