[Pigmented lesions of the genital mucosa]

Pigmented lesions of the genital mucosa are more frequent in women than in men. They represent a spectrum of different benign entities. A biopsy is always recommended when the diagnosis cannot be made with certainty on clinical examination and dermatoscopy. Differential diagnostic considerations include melanocytic nevi, blue nevi and syndromes featuring lentigines. Malignant melanomas of the penis and vulva are uncommon tumors which usually appear in elderly patients. They frequently present as painless palpable nodules at routine examination. The treatment consists of excision with histological control of the margins. An aggressive surgical approach has not been shown to prolong the poor 5-year survival. Cooperation with gynecologists and urologists is essential for the optimal management of such patients.
