Renal cell carcinoma with metastasis to the parotid gland: case reports and review of the literature.

Two cases of renal cell carcinoma metastatic to the parotid gland are presented. The parotid mass was the initial manifestation of the first patient's renal cell malignancy and the pathologic evaluation was the first clue to the diagnosis. The second case demonstrates discovery of metastasis to the parotid gland 8 years after resection of a hypernephroma. A review of the literature on this subject is presented and the pathologic characteristics as well as recommendations for diagnosis and treatment of this entity are reviewed.
