Heterotopic gastrointestinal cyst in the mandible of a young adult: A rare case-report from Syria.

Heterotopic gastrointestinal cyst (HGC) is a rare entity in the head and neck region. The dorsal surface of tongue and the floor of the mouth is the most commonly affected sites and rarely affects bone. Histologic examination reveals a lesion resembling any part in the gastric tract; colonic, intestinal or gastric mucosa. We report a HGC presenting in a twenty-one-year-old Syrian female patient.
