A case of dermoid cyst of the tongue forming a fistula

Dermoid cysts of the tongue are rare. We present a case of dermoid cyst in the tongue muscle. An 18-year-old woman was referred to our department because of bleeding of the tongue. A small mass had been present since birth, but was never diagnosed. The mass was present in the tongue muscle and had formed a fistula on the dorsal surface of the tongue. Previous reports indicated that dermoid cysts of the tongue were smaller and occurred in patients at younger ages as compared with those found at other sites. The patient showed no evidence of recurrence 2 years postoperatively.
