Becker’s nevus (also known as Becker’s melanosis Becker’s pigmentary hamartoma Nevoid melanosis and Pigmented hairy epidermal nevus) is a skin disorder predominantly affecting males. The nevus generally first appears as an irregular pigmentation (melanosis or hyperpigmentation) on the torso or upper arm (though other areas of the body can be affected) and gradually enlarges irregularly becoming thickened and often hairy (hypertrichosis).
