Concomitant Kissing Nevus of Penis and Giant Becker's Melanosis of Lower Limb

Abstract

ABS TRACT Kissing nevi or split nevi are congenital melanocytic nevi on adjoining areas of the body formed as a result of separation during embryogenesis. Most kissing nevi are seen over the eyelids and only a handful of them have been reported over the penis. Becker's melanosis is a common androgen dependent hamartoma with epidermal, melanocytic or smooth muscle origin. Herein, we describe the case of a 20-year-old male who presented with kissing nevi over the glans penis and prepuce. The patient also had a large Becker's melanosis over the left side extending from the lower back to left lumbar area, the lateral aspect of left buttock and thigh till the knee. Our case is the first instance where a kissing melanocytic nevus is associated with Becker's melanosis.
