We present a case of a 64-year-old man with a bilateral nasal obstruction. An endoscopic biopsy taken from the mass revealed a vascular clear cell tumor underneath an intact Schneiderian membrane compatible with a renal cell carcinoma. Following inquiry, it was revealed that the patient had gone through right radical nephrectomy for renal cell carcinomas 17 years prior to admission, a fact that was not known when the biopsy was taken. A following workup showed areas suspicious for metastases in lungs and maxillary sinuses. The patient started treatment with Sunitinib. On five months follow- up, the lung lesions had regressed.
