It is clinically rare to experience secondary renal tumors, though it is not uncommon in autopsy cases. A 60-year-old man, who had undergone right pneumectomy six months ago, was admitted with gross hematuria and dull ache in the right flank. IVP showed a space-occupying lesion in the upper half of the right kidney. Angiograms revealed relatively hypovascular mass with typical encasement vessels at the same site and trans catheter arterial embolization was immediately followed. Transperitoneal right nephrectomy was performed and pathological studies verified secondary squamous cell carcinoma. Preoperative transcatheter embolization of the renal artery for secondary renal tumors is as significant as for primary renal tumors. In case of poor risk patients, it will be indicated for relieving symptoms. In the Japanese literature, 4 clinical cases of the metastasizing renal tumor from the lung cancer were reported in these 20 years.
