Abstract
Dennoid cysts arc a type of teratoma occurred as a result of the sequestration of the skin along the lines of embryonic closure. They occur most commonly on the face, scalp or neck. Approximately 7% occur in the head and neck area. Post-auricular dermoid cysts are extremely rare, reported in few case reports.
Congenital inclusion dermoid cysts form along embryonic fusion lines and contain both dermal and epidermal derivatives. Dermoid cysts of the head and neck arc believed to be congenital inclusion cysts which may present elsewhere in the head. Depending on the location of the lesion, dermoid cysts may contain substances such as nails and dental, cartilage-like, and bone-like structures. If limited to the skin or subcutaneous tissue, dermoid cysts are thin-walled tumors that contain different amounts of fatty masses; occasionally, they contain horny masses and hairs. Dermoid cysts in the skin and subcutis occur mostly on the face, neck, or scalp. Dennoid cysts of the ovary are sex restricted, that is, they occur only in the female population. In other dermoid cysts. no sex predilection has been found. Dennoid cysts have been described in persons of all ages.
