Becker's Nevus Syndrome

Definition

Definition of Becker's Nevus Syndrome
A Becker naevus (Becker nevus) is a late-onset epidermal naevus or birthmark occurring mostly in males. It is also known as Becker melanosis. It is due to an overgrowth of the epidermis (upper layers of the skin), pigment cells (melanocytes) and hair follicles. It develops during childhood or adolescence on the shoulders or upper trunk, occasionally elsewhere.

Treatment

Treatment of Becker's Nevus Syndrome

1. There is no effective treatment for the majority of Becker naevi. However, the dark brown colour is less obvious if the affected area is kept out of the sun so that it doesn't tan.
2. The excessive hairs can be reduced by repeated treatments with a hair removal laser or by electrolysis. The pigmentation can be reduced by a pigment laser, but this is not always effective and it may also be made worse by laser treatment.

Prognosis

Prognosis of Becker's Nevus Syndrome
The naevus remains indefinitely.
