PULMONARY METASTASIS FROM HYPERNEPHROMA DIAGNOSED BY BRONCHOSCOPY

Abstract

Pulmonary metastasis from hypernephroma usually consists of annular masses scattered throughout both lungs. These masses rarely give rise to pulmonary symptoms, and unless there is extension to the Fig. 1.—Primary hypernephroma. pleura, with development of pleural effusion, they seldom produce signs that can be detected by general examination. Extension of a tumor of this type into the lumen of a bronchus, with production of bronchostenosis and other signs and symptoms simulating primary bronchial carcinoma, is sufficiently rare to warrant the following report: REPORT OF CASE A man, aged 58, was first examined at the Mayo Clinic on May 24, 1928.
