The case of a 66-year-old male with a right renal cell carcinoma and a left
testicular mass is reported. Radical nephrectomy and contralateral orchide
ctomy were performed. Histology revealed a metastasis of the renal cell car
cinoma of clear cell type into the left testis. The patient died seven mont
hs post-operatively of disseminated lung metastases. The case demonstrates
the multi-ocular metastatic potential of renal cell carcinoma.
