Heterotopic gastric mucosa of the oral cavity: a rare entity

Abstract

Objective: Heterotopic gastric mucosa found within the oral cavity has been reported as a rare occurrence with less than 30 cases in the English literature. We propose that this entity may not be as rare as originally described. Method: Five cases of heterotopic gastric mucosa in the oral cavity were collected from three institutions. Results: Five new cases of heterotopic gastric mucosa in the oral cavity were confirmed. Conclusions: Heterotopic gastric mucosa of the oral cavity may not be as rare as originally thought.
