Abstract: Objective: To report one case of renal clear cell carcinoma transferred to the nasal cavity and sinuses treated by low temperature coblation assisted nasal malignant tumor resection under nasal endoscopye, and to review the associated literatures.Methods: Under nasal endoscope, the tumor was removed along the lateral wall of the nasal cavity with bipolar electrocautery and coblation. The vaseline gauze was used to stop bleeding, and the tumor was completely removed.Results: The intraoperative frozen section showed a capillary hemangioma. The patient was diagnosed as metastatic renal cell carcinoma to the nasal cavity and sinuses by the results of pathology and immunohistochemical staining. The postoperative recovery was uneventful and the nasal packing was removed 3 d after operation.Conclusion: Renal clear cell carcinoma transferred to the nasal cavity and sinuses is rare; under nasal endoscope, surgical resection is a good procedure to control metastasis.
