title: Heterotopic gastrointestinal cyst of the tongue.
abstract: A 6.5-month-old white male presented with a cyst involving the left posterior half of his tongue which partially compromised his airway. A computed tomography scan revealed that the mass also involved the left floor of the mouth. Surgical excision of the mass was performed, and the mass was demonstrated to be a gastrointestinal heterotopic cyst. The clinical and pathological features of this rare lesion are presented and the pathogenesis is discussed.
