CO₂ laser treatment of a kissing nevus of the penis: an alternative solution for a rare condition

Abstract

Divided or kissing nevi are a rare clinical variant of congenital melanocytic nevi developing in adjacent areas of the skin that undergo cleavage during embryogenesis. Penile lesions are even rarer, with only few cases described in the literature. Typically, they present as two opposing dark colored macular or papular lesions on the glans and prepuce, exhibiting a mirror-image symmetry relative to the coronal sulcus. The proposed management ranges from clinical follow-up to surgical excision. However, in this particularly sensitive location the risk of functional and esthetical complications is high, so an alternative treatment option was proposed. We report a case of a penile kissing nevus with its dermoscopic and histopathological characteristics as well as its successful treatment with the carbon dioxide (CO₂) laser.
