Nevus Sebaceus is a benign, congenital hamartoma of the folliculo-sebaceous apocrine unit and epidermis that often presents at birth, appears to regress in childhood, and grows during puberty, suggesting possible hormonal control. In childhood, the lesion consists of circumscribed hairless yellow-orange colored, waxy, pebble-like, papule or plaque often linear or round or irregular. In puberty the lesion becomes verrucous and nodular. These are generally located on the scalp, face or neck as a solitary lesion and usually present since birth.
