Malignant melanoma of the penis.

A case of malignant melanoma of the penis is herein reported. Malignant melanoma of the penis is rare and accounts for a small percentage of malignant melanomas and of malignant penile lesions. The diagnosis is often delayed by the patient's reluctance to consult a physician and by the intrinsic difficulty in clinical diagnosis of such a rare neoplasm. The surgical treatment is not standardized and is shortly discussed. In general, prognosis is poor and most patients die within a few years due to distant metastasis.
