Metastatic Renal Cell Carcinoma to the Orbit and the Ethmoid Sinus

Abstract

The orbit is an unusual site for metastatic renal cell carcinoma (RCC), and concurrent metastases of RCC to the ethmoid sinus and the orbit occur very rarely. The treatment goal of orbital and paranasal metastatic RCC is total exenteration. We report a rare case of metastatic RCC to the orbit and the ethmoid sinus. The patient underwent total exenteration, craniotomy, and total maxillectomy. Six years after surgery, the patient showed no sign of metastasis and had successful cosmetic result by using orbital prosthesis.
