title: Metastasis of renal cell cancer to the ethmoid sinus.
abstract: The origin of metastatic tumors in the nasal or paranasal sinuses is often renal cancer, and metastasis to the nasal or paranasal sinuses sometimes takes a long time after nephrectomy. The present paper deals with one patient with metastasis of renal cancer to the ethmoid sinus 2 years after nephrectomy. Even though many metastatic tumors originating from renal cancer develop in multiples, most metastatic tumors in the nasal or paranasal sinuses are single and treated surgically. However, even if multiple tumors are found in the nasal and paranasal region and other organs, surgery will be effective in preventing epistaxis and subsequent anemia. Also, when removing a tumor it will be effective to identify the feeding arteries of the tumor, perform embolization therapy, and clip the necessary arteries.
