Nephrogenic epistaxis.

Metastatic renal cell carcinoma (RCC) in the nose and paranasal sinuses is very rare. We report an unusual case of metastatic RCC that presented as recurrent epistaxis ten years after curative nephrectomy. The purpose of this report is to draw the attention of clinicians to the possibility of metastatic RCC in patients with recurrent epistaxis and nasal mass. We also discuss treatment options and review the relevant literature.
