Is Becker’s nevus bad?

Becker’s nevus (also known as “Becker’s melanosis”, “Becker’s pigmentary hamartoma”, “nevoid melanosis”, and “pigmented hairy epidermal nevus”) is a benign skin disorder predominantly affecting males.

What is the cause of nevus?

These marks are thought to be caused by a localized increase in melanocytes as a baby grows in the womb. Melanocytes are the skin cells that produce melanin, which gives skin its color. A nevus has an increased amount of melanocytes. The condition is thought to be caused by a gene defect.

How do you treat Becker nevus?

Treatment is primarily for cosmetic reasons (hyperpigmentation or hair growth) and may include Ruby laser treatment or laser-assisted hair removal. In very rare cases, Becker’s nevus is associated with other skin features; muscular or skeletal features; or underdevelopment (hypoplasia) of the breast.

Are nevus hereditary?

Congenital nevi are thought to be caused by a genetic mutation, called a sporadic mutation, which develops randomly as a baby grows in the womb. The condition is not inherited.
