Divided Nevus of the Penis: An Unusual Location

Arch Dermatol. 1998;134(7):879-880. doi:

Divided nevus or kissing nevus is usually defined as a congenital melanocytic nevus that occurs on adjacent parts of the upper and lower eyelids and may appear to be a single lesion when the lids are closed. Other types of divided nevus have been reported less frequently: nevus spilus on the eyelids, mast cell nevus, and epidermal nevus on the fingers.

We report the first case of a patient with divided nevus located on his penis.

A 7-year-old boy had a melanocytic nevus on his penis. When he was 4 years old, the nevus was first noticed on the occasion of the release of preputial adhesions. Results of the physical examination revealed that the nevus was located on each side of the coronal sulcus: the inner face of the prepuce and the adjacent glans (Figure 1). Only the coronal sulcus was exempt from melanocytic pigmentation.
