Gastric heterotopia, also known as gastric choristoma or enterocystoma, refers to histologically normal gastric mucosa that is located in an aberrant anatomical location. The majority of these lesions are found within the gastrointestinal system. Potential locations include the small intestine, thoracic esophagus, stomach wall, Meckel diverticulum, biliary tract, gallbladder, pancreas, umbilicus, appendix, rectum, and vitelline duct.1 On rare occasions, gastric heterotopia is found in the region of the head and neck.
