Nevus sebaceous is a hairless area that is present at birth. It most often occurs on the scalp and less often on the face, neck or trunk. The surface may be smooth or pebbly. The color is often yellow to yellow-orange.
Nevus sebaceous is a small area with too many sebaceous (or oil-producing) glands. This type of birthmark is not inherited. It may occur in both males and females of all races. Nevus sebaceous grows at the same rate as the child. Sometimes, it is seen at birth. The hormones from the mother may cause the sebaceous glands to be active. As the baby ages and hormone levels decrease, it isn’t seen as much. Also, as the child enters puberty, the lesion may become thick, raised, and nodular.
Very rarely a cancerous growth may develop in it later in life
