Article Abstract

Becker melanosis, also known as Becker nevus, is a relatively common cutaneous hamartoma. The condition is classically characterized by a unilateral, hyperpigmented patch with varying degrees of hypertrichosis on a peripubertal individual. As Becker nevi are generally singular in a given individual, there are very few reported cases of multiple or bilateral lesions. We herein report a rare case of bilateral, symmetrical, non-syndromic Becker melanosis and we discuss possible pathogenesis and current treatment options.
