Solitary metastasis of renal cell carcinoma to the parotid gland 10 years after radical nephrectomy.

Renal cell carcinoma metastasis to the parotid gland after tumor nephrectomy is extremely rare. We report a case of solitary parotid metastasis from clear cell renal cell carcinoma in a 59-year-old woman, who presented 10 years after primary treatment. To our knowledge this is the first case in the published literature presenting with solitary parotid metastasis after such a long time. Superficial parotidectomy with preservation of the facial nerve was performed. One year after, the patient developed contralateral multiple kidney tumors and underwent left radical nephrectomy. She is currently on a dialysis program and no additional metastasis has been observed for 18 months.
