Abstract
It is pointed out that reports of hypernephroma metastases in the nose and paranasal sinuses are rare. On the basis of four personal cases, it is suggested that such metastases are, however, presumably far more common in this region than can be inferred from the literature.
An account is given of certain characteristic properties of both hyper-nephroma and its metastases that hamper an early diagnosis. It is stressed that treatment of these metastases in the nose and paranasal sinuses presents special problems, in view of the great tendency to haemorrhage.
