Becker's nevus.
Becker's nevus is a benign lesion that may be congenital or acquired, macular or papular, hairless or hypertrichotic. It is most commonly located on the upper trunk of young men. Histologic examination shows characteristic changes, but dermal nevus cells are never present. Bony and soft tissue structural anomalies occur with increased frequency in patients with Becker's nevus.
