Abstract

The clear cell carcinoma is a relatively rare tumor, represented approximately 85% by renal cell carcinoma (RCC), but has a characteristic of early metastatic, which sometimes spread to unusual places. Metastatic tumors in the paranasal sinuses are very rare. This case report a 65 years-old patient who presented sinusitis and epitaxis as a first sign of renal cell carcinoma with metastasis to the right maxillary sinus, which was opereted at Lagoa Hospital—RJ and strengthen the inclusion of this disease in the differential diagnosis of sinus disease. The renal cell carcinoma is a relatively rare tumor, representing approximately 3% of malignant tumors. About a third of patients with renal cell carcinoma have metastasis at diagnosis. The sinuses are a rare location of metastasis. The maxillary sinuses and the paranasal sinuses are most commonly affected by metastatic tumors to the sinuses region. The most frequent primary tumor to metastasis to paranasal sinuses is the renal cell carcinoma. This report highlights the rarity of the case and the importance in the differential diagnosis of sinus disease.
