A case of metastatic renal cell carcinoma to the maxillary sinus

Abstract

We report a rare case of a 44-year-old man with metastasis from renal cell carcinoma to the right maxillary sinus. The patient had undergone a tumor nephrectomy approximately six years previously. Intermittent epistaxis was the first symptom. The solitary metastatic tumor was resected by a maxillectomy with closure of the large cavity using a microvascular latissimus dorsi flap. Additionally, conservative treatment with alpha-interferon was administered. We describe the clinical course with a review of literature.
