Endoscopy and radiography lead to the correct diagnosis in most patients with ectopic pancreas. Gastric lesions are found at the antrum in 85% to 95% of patients, either on the posterior or anterior wall, most commonly along the greater curvature. The most common characteristic gross feature is a central depression, which corresponds to a ductal orifice.Histopathologic diagnosis is straightforward when pancreatic acini, ducts, islets of Langerhans, and intervening connective tissue are present. Here we report a case of a large, ectopic, pancreatic mass, about 7 cm in size, which was incidentally found in an unusual location during screening gastroscopy. To our knowledge, this is the first description of such a large, ectopic, pancreatic lesion in an unusual location.
