Ectopic pancreas is often asymptomatic and, in most children, is an incidental finding during EGD or upper GI series. True prevalence of ectopic pancreas in children is unknown. In the stomach, ectopic pancreas is located on the greater curvature of the antrum and appears as a small, less than 1cm, dome-shaped lesion with the central depression (Figure 5.59). It is usually covered by normal gastric mucosa. Sometimes, the lesions may be less protruded toward the gastric lumen and may appear as “bagel” or “doughnut” structure. A biopsy is not indicated as an ectopic tissue arises from the submucosal or subserosal layers
