Abstract
Metastases from renal cell carcinoma to the sinonasal tract are rare. Only 1% of patients with renal cell carcinoma have metastases solely in the head and neck region. We report a case of a 61-year-old man who was suffering from recurrent epistaxis. A dark red and hemorrhagic tumor was observed in the left meddle meatus. Histopathological examination from a biopsy of the tumor revealed clear cell carcinoma. A paranasal CT scan showed a 15-mm-sized soft-tissue mass in the left meddle meatus. A contrast-enhanced viewing showed this mass slightly enhanced. An abdominal CT scan showed a 35-mm-sized mass in the right kidney. We diagnosed this case as metastatic renal cell carcinoma in the nasal cavity. Endoscopic resection of the nasal tumor was performed for an improvement of epistaxis, and then nephrectomy was added by an urologist. At present no recurrent or metastatic lesions have been observed.
