Abstract: We report the first documented case of malignant melanoma obstructing ureters of both moieties of a duplex kidney and contralateral single moiety ureter in a 51-year-old male. The patient presented with fever, coryzal symptoms, and liver function test derangement several years after 2 superficial spreading melanomas were excised with clear margins. Ultrasonography demonstrated hydronephroureter in both moieties of a complete right-sided duplex kidney. Retrograde pyelograms showed bilateral hydronephroureter and filling defects in all 3 ureters. Biopsied tumor cells were positive for S100, Melan A, and HMB45. Cutaneous melanoma metastasizing to ureters is a rare phenomenon and can present a diagnostic challenge to clinicians if clinically silent.
