Prostate metastasis of malignant melanoma

Metastatic malignant melanoma of the prostate is extremely rare in clinical practice, and only one case has been reported in the English literature in the past 30 years. We report a case of malignant melanoma that metastasized to the prostate and review the current literature. A 50-year-old man with a history of malignant melanoma metastasis to the left axilla, which was excised 3 years ago, presented with lower urinary tract symptoms and gross hematuria. He underwent cystoscopy and transurethral resection of the prostate. The pathological examination showed metastatic malignant melanoma of the prostate gland. The patient died 6 months after the transurethral resection.
