A 65-year-old man presented with a tumor measuring 22×24×14mm at the border of the tongue. He had a history of renal cell carcinoma and had undergone a right radical nephrectomy. He also had multiple metastatic lesions to the lungs. A biopsy of the tongue was done. The biopsy specimen showed a renal cell carcinoma that had metastasized from the kidney.
Metastasized tumors generally have a very poor prognosis. Therefore, it is very important to consider the patient's quality of life when choosing the procedure for metastatic tumors.
The patient was admitted to the hospital. The tumor of the tongue was resected with a KTP laser under local anesthesia. The resected specimen showed that renal cell carcinoma had invaded the muscle layer of the tongue.
Forty-eight days after the operation, re-epithelialization of the wound was completed with no evidence of infection. There was no postoperative dysfunction.
We conclude that tumors metastasizing to the oral cavity should be aggreassively treated.
