Abstract

Heterotopia refers to the finding of normal tissue in foreign sites, entirely separate from the main organ. Heterotopic gastric mucosa has been observed throughout the alimentary tract, everywhere from the oral cavity to the rectum. However, occurrences in the umbilicus are an extremely rare and peculiar phenomena. We report the case of heterotopic gastric mucosa in the umbilicus.
