Recurrent primary malignant melanoma of the urinary bladder; a case report.

Primary malignant melanoma (PMM) of the urinary bladder is a rare disease. Symptoms include gross hematuria and irritative LUTS. The diagnosis is made with cystoscopy and TURBT. Treatment options include TURBT and adjuvant therapies. We present a 61-year-old female who was referred with persistent irritative LUTS without gross or microscopic hematuria. After undergoing cystoscopy, TURBT, and extensive workup, she was diagnosed with PMM of the urinary bladder. Due to her past medical history, recurrent PMM of the urinary bladder was the final diagnosis. She refused to receive further treatment or refer for follow-up.
