Epidermal nevus: surgical treatment by partial-thickness skin excision.

A child with epidermal nevus, systematized, is reported in which diffuse areas of pruritic and bleeding tissue were treated by partial-thickness skin excision, a technique reported to have been successful in other forms of benign dyskeratosis, such as psoriasis. At age 5 years, a test region of the anterior thigh was treated and remained disease free with an acceptable scar. At age 8 years, this technique was applied to the back, buttock, calf, and thigh. While the areas remain disease free, they have, unfortunately, healed with hypertrophic and keloid scars.
