title: A case of metastatic malignant melanoma presenting with hematuria.
abstract: We report a case of metastatic malignant melanoma that presented with macroscopic hematuria and lower urinary tract symptoms. Effective palliation of urinary tract symptoms was achieved with transurethral resection of metastatic lesions in the bladder. However, the patient was lost due to widespread disease despite systemic therapy. Solitary or multiple dark blue-black nodular or vegetating lesions encountered during cystoscopy should raise the suspicion of metastasis of malignant melanoma and be investigated accordingly.
