Context It is rare for ectopic pancreatic tissue to cause symptoms or require treatment, however diseases of normal pancreas may also occur in ectopic pancreas tissue. Case report This report describes the clinical, endoscopic, radiologic and histologic features of a pseudocyst occurring in gastric ectopic pancreas in a 19-year-old man. The difficulty and implications of making an accurate preoperative diagnosis are highlighted. Conclusion Ectopic pancreatic tissue, although rare, should be considered in the differential diagnosis of a submucosal gastric mass.
