Primary malignant melanoma of prostate: a case report.

ABSTRACT

While primary genitourinary melanomas account for less than 1% of all melanoma cases, prostatic melanoma is extremely uncommon. These patients are challenging to identify, with a dismal prognosis. We reported a 52-year-old male patient who presented with lower urinary tract symptoms in the last one and a half months. The patient underwent Holmium laser enucleation of the prostate, and the histopathology result of the resected specimen showed prostatic melanoma. Investigations for systemic melanoma evaluation were negative, and the patient underwent radical cystoprostatectomy, urethrectomy, and bilateral lymph node dissection. The patient refused chemotherapy, developed lung metastasis shortly after surgery at three months, and succumbed to the metastatic disease with overall survival of 6 months. In conclusion, primary malignant melanoma of the prostate is a very rare disease. The most logical therapeutic strategy is aggressive surgical resection, followed immediately by adjuvant therapy.
