Skull Base Surgery of Metastatic Renal Cell Carcinoma to the Ethmoid Sinus

We present a patient with metastastic renal cell carcinoma to the ethmoid sinus. A 68-year-old male consulted with complaints of left epistaxis and nasal cavity tumor. His status was post left total nephrectomy for renal cell carcinoma. The histological diagnosis was renal cell carcinoma (clear cell type). We performed skull base surgery for total ethmoid sinus resection. We report on this case and discuss metastasis of renal cell carcinoma to the head and neck region.
