Gastric heterotopia in the gallbladder: a case report.

ABSTRACT

A case of incidentally identified ectopic gastric mucosa in the gallbladder of a 26-year-old man with a three year history of recurrent abdominal pain is presented. The aberrant gastric tissue consisted of gastric pyloric glands and fundic glands. Focal intestinal metaplasia characterized by goblet cells containing sialomucin was seen in the surrounding gallbladder mucosa but no metaplastic change was seen in the heterotopic tissue.
