Metastases to the sinonasal tract are infrequent occurrences from primaries below the clavicles. The total number of reported cases to date is less than 100. There is, however, complete unanimity concerning the histologic type of metastatic neoplasm most often encountered. An interesting phenomenon, generally attributable only to breast and renal cell carcinoma, is the late recurrence of the malignant tumor, even 10 or more years after operation. A 61 year-old-male was admitted to ENT due to frequent epistaxis and right facial swelling. CT scan revealed a huge soft tissue density mass I right maxillary sinus with extension into nasopharynx and deviation of nasal septum. The histologic diagnosis was metastatic renal cell carcinoma. He had left nephrectomy because of renal cell carcinoma, 14 years ago. We report a case of metastatic renal cell carcinoma of maxillary sinus in view of rarity, and a brief review of the literature related to this type of tumor is presented.
