A Case of Metastatic Renal Cell Carcinoma to the Maxillary Sinus Treated with Tyrosine Kinase Inhibitor / 대한이비인후과학회지

ABSTRACT

Renal cell carcinoma is a rare metastatic malignant neoplasm of the paranasal sinus. The clinical picture and radiologic findings might sometimes be insufficient to suspect metastatic renal cell carcinoma. Therefore, the definite diagnosis should be made according to the result of intraoperative biopsy. Recently, tyrosine kinase inhibitor, sunitinib, is considered as an effective agent in the treatment of metastatic renal cell carcinoma. We report a case of 69-year-old patient with metastatic renal cell carcinoma of the right maxillary sinus with accompanying fungal sinusitis. After 6 times of chemotherapy with sunitinib malate, there was no sign of recurrence or local advancement of the tumor during the 1-year follow-up period.
