Clear cell transitional carcinoma of the bladder is a subtype of transitional carcinoma that morphologically resembles a clear cell renal cell carcinoma. Although kidney tumors do not frequently metastasize to the bladder, the recurrence after a clear cell renal cell carcinoma has been reported even several years after nephrectomy. We report the case of a male patient to whom radical nephrectomy for a clear cell renal cell carcinoma has been done, with a bladder tumor featuring polygonal cells with abundant clear cytoplasm deeply infiltrating the vesical wall. We discuss the morphologic features, the immunohistochemical staining with a new marker and the UroVysion FISH analysis to achieve a definitive diagnosis.
