[Metastasis of clear cell renal cancer to the nose and nasal sinuses].

Metastases of malignant tumours of remote location to the nose and nasal sinuses are rare. The possibility of their occurrence should be, however, taken into account, since rhinological manifestations may precede the diagnosis of primary tumour. This is true especially in the case of clear-cell renal cancer whose metastases are the most frequently found secondary malignant tumours of the nose and nasal sinuses. A case is described of clear-cell renal cancer metastasis to the frontal sinus.
