A 71-year-old woman underwent left radical nephrectomy for renal cell carcinoma (clear cell carcinoma, pT1bN0M0) ten years previously. She noticed a tumor on the tip of her tongue and was admitted for dental and oral surgery. The tumor was about 10 mm in size, and tumor resection was done. It was pathologically diagnosed as clear cell carcinoma, which was metastasis of renal cell carcinoma. Computer tomography scan during the same period revealed left hilar lymph node and bilateral lung metastases. We chose to use sunitinib as the treatment for the metastases. Computer tomography revealed a complete response (CR) after sunitinib treatment was given for 10 months, and we are still continuing the treatment to maintain the CR status.
