As the name suggests this is a type of mole or nevus which is produced by the outer most layer of the skin called epidermis. They are benign fleshy or warty lesions which are typically seen at birth but occasionally they develop after the child is born and the size of these nevi vary in individual cases. They are rare to occur and there are two common types which are recognised as Epidermal Nevus. There are a few varieties of this has been described and has named differently depending upon its cell type.
Types of Epidermal Nevus
The first one is called Keratenocytic Epidermal Nevi which are typically present on the limbs or the torso. These can be flat or raised brown patches and may have a velvety feel to it. As the age goes by these nevi can get darker.The other type of epidermal nevus which involves the epidermal cells that make certain sweat glands or, the sebaceous glands (oil producing glands in the skin, and these nevi originating from these structures of the skin called organoid epidermal nevi and a common type of these nevi is called Nevus Sebaceous. The nevus of this group appears as yellowish orange, a waxy surface which is usually present on the face or the scalp. Does epidermal nevi lead to cancer?
Epidermal nevus syndrome
These patches if they are present on the scalp may have associated alopecia (hair loss) and with time they may become darker and thicker and appear as verruca like growth but they are not verruca. They generally do not ever change to cancer but rarely cancer development in these growths has been reported. Most people who have epidermal nevus generally have no other abnormalities. Rarely, some epidermal nevus also has associated problem of brain, bones or even eyes. In these situations, they are called epidermal nevus syndrome, and, in such situations, one would generally need input from hospital specialist. How to treat Epidermal Nevus?As these lesions are generally harmless therefore it can be left untreated but if you have cosmetic concerns then we advise you to seek the help of local doctors including local dermatologists. If you are keen on getting it removed, then it is best to be removed by Carbon dioxide laser vaporisation which generally gives you lot better results than simple shave excision. A biopsy is generally recommended to confirm the diagnosis.
