Heterotopia is defined as the presence of a tissue outside of its natural location. Ectopic or heterotopic pancreatic tissue is a form of choristoma and is considered an embryological abnormality. Stomach, duodenum, jejunum and spleen are common localizations. The gallbladder is a very rare localization.
