title: Oral congenital cystic choristomas: a case report.
abstract: Solitary choristomas containing gastrointestinal mucosa occur rarely in the tongue and the oral mucosa and usually present as an asymptomatic mass. This report documents the occurrence of two congenital intraoral cystic choristomas in a 5-month-old male infant. The cysts were located on the dorsum of the base of the tongue and left floor of mouth anterior to the lingual cyst. Both cysts were lined by nonkeratinizing squamous epithelium and gastric, intestinal, and respiratory epithelium. The cysts were excised by an oral approach.
