title: A Case Report of Primary Recurrent Malignant Melanoma of the Urinary Bladder.
abstract: Primary malignant melanoma of the urinary bladder is a rare neoplasm, with only 19 cases reported to date. We present a case report of an 84-year-old woman who underwent transurethral resection of a mucosal melanoma of bladder origin. She had no previous or concurrent diagnosis of cutaneous melanoma. The patient underwent transurethral resection of the tumor 5 months before presentation at our center with a recurrent, muscle-invasive tumor located in the bladder trigone, with evidence of bone metastasis. Malignant melanoma of the urinary bladder carries a poor prognosis and poses a therapeutic challenge to urologists who manage patients with this rare disease.
