Nevus comedonicus of glans with unusual morphology due to manipulation.

Abstract

Nevus comedonicus, an uncommon skin condition, was originally termed "comedo nevus" by Kofmann in 1895. It is characterized by the clusters of pits-containing black keratinous plugs resembling blackheads. Conventionally, nevus comedonicus manifests at birth (in 50% of cases) or during the first decade of life. The commonly affected areas include the head, neck, chest, upper, and lower limbs, with patterns ranging from unilateral, bilateral, linear, interrupted, segmental, to blaschkoid. While genital nevus comedonicus is rare, some cases have been reported. In this report, we present a case of nevus comedonicus on the glans, underscoring the importance of considering nonsexually transmitted disease-related causes for genital lesions.
