Congenital dermoid cyst of the oral cavity with gastric choristoma.

Abstract

A case of congenital dermoid cyst of the buccal floor occurring simultaneously with a gastric choristoma is reported. Only one other similar case could be found in our review of the literature. A tracheostomy was done to relieve airway obstruction. Complete excision was achieved through an intraoral approach. A quick review of the embryology of the floor of the mouth is presented as well as the classification and differential diagnosis of these lesions.
