Malignant melanoma metastatic to the bladder is a relatively common autopsy finding, but rarely manifests clinically as it is usually a late finding in the course of the disease. Herein is the report of a case of muscle invasive malignant melanoma at the dome of the urinary bladder treated by radical transurethral resection with no evidence of bladder recurrence four years later.
