ABSTRACT
Dermoid cyst in the oral cavity is uncommon. It represents an abnormal cystic development in the midline as a result of displaced or enclaved embryonic epithelium during the midline closure of the bilateral first and second branchial arches.
Although epidermoid and teratoid cyst is more common in infant, dermoid cyst is more common in adult in the second or third decades. There is no sexual predilection.
The treatment of choice is complete surgical excision and the prognosis is excellent.
Recently the authors experienced a large epidermoid cyst on the floor of the mouth above the mylohyoid muscle which is excised by intraoral approach.
