A new neurocutaneous syndrome: nevus sebaceus syndrome.

We describe a case of nevus sebaceus syndrome characterized by a linear sebaceous nevus, extending on the left half of the face from forehead to lower neck, including the auricle; alopecia on the temporoparietal region; generalized hypotonia; insufficiency of eyes in following moving objects and insufficiency in controlling the head; lipodermoid cysts in the left and right eyes; bilateral conjunctival masses; corneal vascularization in the right eye; coloboma of the left eyelid and right optic disc. This is a rare case of a sebaceous nevus occurring concomitantly with optical and central nervous system abnormalities.
