Excerpt

Becker’s nevus, also known as Becker’s melanosis, Becker’s pigmentary hamartoma, or nevoid melanosis, can occur in both males and females either at birth or during adulthood [1]. Its pathogenesis is not clear although pathogenic roles of genetic background and activation of androgen receptor have been postulated [2, 3]. Becker’s nevus commonly manifests as ipsilateral lesions, but subjects with bilateral lesions have also been reported [4, 5]. Pigmented skin patch with or without hypertrichosis is the main clinical manifestation [1, 6]. Becker’s nevus can be complicated with other cutaneous disorders, such as eczema and basal cell carcinoma [7, 8]. Although Becker’s nevus alone is asymptomatic, cosmetic concerns may be bothersome. …
