[Endobronchial and laryngeal metastasis. An unusual form of dissemination of the hypernephroma].
OBJECTIVE
To describe uncommon forms of dissemination of hypernephroma.


METHODS
A case of hypernephroma that metastasized to the laryngeal vallecula and bronchi is presented. Our findings were compared with those reported in the literature. The diagnostic, radiological, clinical aspects and route of dissemination of some atypical sites of metastasis are discussed.


CONCLUSIONS
It is important to be familiar with these atypical sites of metastasis since these lesions may appear at the same time or before the primary tumor is detected. A high index of suspicion will make a major impact on treatment and prognosis. The radiological findings are undoubtedly of enormous value, although histological confirmation is necessary in order to make the correct diagnosis.
