Metastatic renal cell carcinoma to the mandible: report of case.

A rare instance of a primary clear cell renal carcinoma metastasizing to the left mandible has been presented. Metastatic tumors to the jaws are relatively uncommon and involve the mandible more frequently than the maxilla. When they occur, the primary tumor is most likely to be an adenocarcinoma from the breast, lung, or kidney. A pulsatile mandibular lesion, found not to be an arteriovenous fistula, suggests a metastatic renal carcinoma until it is disproved.
