Metastatic carcinoma of the nose and paranasal sinuses is generally not considered because the primary lesion is much more likely to be diagnosed. Although it is rare, the renal cell carcinoma occasionally metastasizes to the nose and paranasal sinuses. These metastases are usually vascular and may either clinically precede the diagnosis of the renal primary tumor or may occur many years after apparently successful surgery of the primary tumor.

Recently we experienced a case of metastatic renal cell carcinoma to the ethmoid sinus in a 52 years old patient that occured 9 years after nephrectomy. Surprisingly, the patient also had metastatic lesion to the lung and had had metastatic lesions to the chest wall, right cheek area, paraumbilical area and right thyroid gland after nephrectomy. We performed medial maxillectomy for the removal of the metastatic lesion and there was no evidence of recurrence through the 21 months follow-up. Early recognition of this rare condition and surgical removal of metastatic tumor are recommended to prolong the patient’s life.

We report this case with a review of literatures.
