title: 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.
  
  
  METHODS
  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.
