Nevus sebaceous on the scalp

Nevus sebaceus or sebaceous nevus (the first term is its Latin name, the second term is its name in English; also known as an "Organoid nevus"[1]:661 and "Nevus sebaceus of Jadassohn"[2]:773) is a congenital, hairless plaque that typically occurs on the face or scalp.[3] Such nevi are present at birth, or early childhood, affecting males and females of all races equally.[4] The condition is named for an overgrowth of sebaceous glands in the area of the nevus.

Skin growths such as benign tumors and basal cell carcinoma can arise in sebaceous nevi, usually in adulthood. Rarely, sebaceous nevi can give rise to sebaceous carcinoma.[5] However, the rate of such malignancies is now known to be less than had been estimated. For this reason, excision is no longer automatically recommended.[6]
