Clear cell carcinoma of the bladder in a patient with a earlier clear cell renal cell carcinoma: a case report with morphologic, immunohistochemical, and cytogenetical analysis.
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.
