DERMOID CYSTS THE ORAL CAVITY

Dermoid cysts are lesions that occur in every parts of human body. The term dermoid cyst has been rather loosely applied to a number of presumably dysodontogenetic cystic lesions wherever they occur in the body. Defined loosely dermoid cyst of the head and neck account for nearly 7% of all dermoid cyst. These cysts are not related to the so-called dermoid cysts of the mediastinum, the ovary, the testes of the pineal or hypophyseal regions, which are the neoplasms and cystic teratoma. These lesions are thought to develop from either an ectodermal enclavement at the time of closure, or from traumatic implantation of epithelial tissues. 12 cases of dermoid, epidermoid cysts are presented here. The current concepts of dermoid, epidermoid cysts are discussed and the literature concerning the histogenesis, sex, age, location, size and histopathology of the unusual lesion reviewed.
