Bilateral dermoid cysts of the upper lip.

Dermoid cysts are benign tumors found throughout the body. They are either congenital or acquired. Derived from both ectoderm and mesoderm, they are often diagnosed in childhood. Dermoid cysts of the head and neck region account for less than 10% of all dermoid cysts. The most common locations of the cysts are the periorbital region and the neck. We expose the case of a 47-year-old man who presented with bilateral dermoid cysts of the upper lip. Only 1 case of unilateral dermoid cyst of the upper lip is referenced in the literature. Authors report the first case of bilateral dermoid cysts and discuss its possible origins.
