구강저에 발생한 유피낭종 2예

Abstract

Dermoid cysts in floor of mouth are relatively rare. The term dermoid cyst is used to describe 3 cysts that are closely related histologically: dermoid cyst, epidermoid cyst, and teratoma. These are frequently mistaken as other pathology because of their location and rarity. Complete surgical excision is the treatment of choice and the recurrence is extremely rare. We report each case of epidermoid cyst and dermoid cyst of the floor of the mouth with a brief review of literatures.
