Overview


Becker's nevus is a late-onset, large, brown birthmark occurring mostly in males. It typically develops during childhood or adolescence on the shoulders or upper trunk, but occasionally it develops on other areas of the body. After puberty, it often becomes darker and more hairy (hypertrichosis), and acne may develop within the nevus in some individuals. Becker's nevus is due to an overgrowth of the epidermis (upper layers of the skin), pigment cells (melanocytes) and hair follicles. Treatment is often primarily for cosmetic reasons and may include laser treatment or electrolysis for excessive hair growth; pigment laser treatment to reduce pigmentation; and standard acne therapy.[1]
