Primary malignant melanoma of prostate.

Area of Science:

• Urologic Oncology
• Dermatology
• Pathology

Background:

• Primary genitourinary melanoma is exceedingly rare, comprising <1% of all melanoma cases.
• Most reported prostatic melanomas actually arise from the prostatic urethra.

Observation:

• This report details a case of primary malignant melanoma of the prostate.
• The diagnosis was incidentally made during a transurethral resection of the prostate (TURP).

Findings:

• Confirms the rarity of primary prostatic melanoma.
• Highlights the importance of considering urethral origin for suspected prostatic melanoma.

Implications:

• Underscores the diagnostic and management difficulties posed by rare genitourinary malignancies.
• Suggests vigilance for melanoma in prostatic tissues, especially during TURP procedures.
