Becker’s Nevus

Abstract

Becker's nevus is characterized by the presence of a light or dark brown patch or plaque with a sharply outlined but irregular border that resolves into smaller pigmented spots, arranged in a checkerboard pattern. In male patients, the lesion may show increased hairiness after puberty. Becker's nevus is a fairly common condition, but often overlooked or misdiagnosed."Becker's nevus syndrome" represents one of the epidermal nevus syndromes and denotes the simultaneous occurrence of Becker's nevus and unilateral breast hypoplasia or other cutaneous, muscular, or skeletal defects. All of these anomalies tend to show a regional correspondence to the nevus and are mostly ipsilateral.
