Dermoid cysts are malformations that are rarely observed in the oral cavity. Histologically, they can be further classified as epidermoid, dermoid or teratoid. We report a case in which a 25-year-old man developed an epidermoid cyst presenting as a large sublingual swelling causing speech and swallowing difficulties. ⋯ Microscopic examination revealed a dermoid cyst of the epidermoid type. After 12 months of follow up, the cyst had not recurred. This case shows that dermoid cysts may be successfully diagnosed and managed using a series of simple yet effective clinical manoeuvres.
