We present the case of a patient with malignant melanoma of the glans penis and urethral meatus, which was found in a 60-year-old man with non-healing ulcerative penile lesion and bilateral clinically palpable inguinal lymphadenopathies at diagnosis. A diagnostic biopsy showed the characteristics of a malignant melanoma. Incisional biopsies from the cutaneous lesions on his glans penis and urethra were performed. Histopathological examination of both specimens showed generally ulceronecrotic surface and numerous atypical melanocytic cells. The diagnosis of giant cell melanoma was made. Two months later, bilateral inguinal lymph nodes dissection was performed. Histopathological examination of both specimens demonstrated malignant melanoma metastasis. Three months after the diagnosis, the patient underwent partial penectomy. High-dose interferon-alpha-2b treatment was started. Early diagnosis is of paramount importance, as the prognosis becomes very poor with an advanced tumor stage.
