Metastasis of renal cell carcinoma to the bladder

Abstract

Renal cell carcinoma is an uncommon source of bladder metastases. Here we report a case of renal cell carcinoma that metastasized to the bladder. A 73-year-old woman complained of gross hematuria. Abdominopelvic computerized tomography showed a bladder mass and a heterogenous enhancing mass in the lower pole of the left kidney with left vein thrombosis. The pathological analysis of the resected bladder specimen revealed metastatic renal cell carcinoma of the clear cell type. © The Korean Urological Association, 2013.
