Abstract

It is universally known and accepted that the development of a certain type of tissue outside its usual location, like in the gastrointestinal tract, can occur. This is a relatively common situation in the upper region of the gastrointestinal tract. However, the development of gastric mucosa in the gallbladder is a rare find. The following is the case of a 22-year-old male with an 18 mm gallbladder polyp, who electively underwent a laparoscopic cholecystectomy, having been diagnosed at a histopathological level with heterotopic gastric mucosa in the gallbladder. This brief article also aims to provide a reflection on the possible evolution of neoplasms from this histological change, based on the doubts raised in literature.
