Oral metastasis as initial presentation of renal cell carcinoma: a case report with review of literature.

Abstract

Metastasis of renal cell carcinoma (RCC) to the head and neck region is rare. The metastases of RCC are radioresistant with surgery as the primary treatment modality. Here, we present a case of a 73-year-old male who presented with left facial swelling which on biopsy and immunohistochemistry showed metastatic RCC. The patient was re-evaluated again and the left renal primary was found out.
