Sublingual dermoid cyst: Case series

Dermoid cysts in the floor of the mouth may be congenital or acquired. The congenital form originates from embryonic cells of the 1st and 2nd branchial arch. The acquired form may be due to traumatic or iatrogenic causes. Its occurrence is estimated to be from 1.6% to 6.9% of the dermoid cysts of the body in adults. They may be classified anatomically and histologically. Anatomically, based on the location while histologically, they are divided into epidermoid, dermoid cysts, and teratomas. Enucleation through intraoral and/or extraoral approach is the method of treatment. A case series of dermoid cysts in the floor of the mouth are presented in this article; and an evaluation with regard to pathology, clinical findings, and treatment is discussed.
