Late tonsil metastases from renal cell cancer: a case report.

The occurrence of renal carcinoma metastasis to the head and neck region is extremely rare. Some authors have reported metastasis of renal cell carcinoma to the parotid glands, nose and paranasal sinus, tongue, larynx, thyroid and palatine tonsil. In this report we describe a rare case of renal cell cancer metastasized to the right tonsil in a 76-year-old man with previously diagnosed bone and lung metastases. To the best of our knowledge this is the first documented example of radiotherapy treatment in this type of presentation. Radiotherapy was effective in treating the lesion with satisfactory functional results.
