title: Kissing melanoma or kissing nevus of the penis?
abstract: Divided, or so-called kissing nevi of the penis, which are separated during embryogenesis, are very rare, with only seven studies reported to date. We present a case of a 30-year-old patient with a divided nevus located at the penis that rapidly changed in size and color within 4 months. These clinical features and the histopathologic appearance of both parts led to the diagnosis of malignant melanoma. Melanoma of the penis is very rare, and the prognosis is poor. This could be the first case of a "kissing melanoma" of the penis reported in published studies.
