[Bronchial biopsy and fiberscopy].

The authors report the results of bronchial biopsies carried out during fiber endoscopy in 165 patients, including 100 bronchial carcinomas, 17 cases of tuberculosis, 7 cases of sarcoidosis, and 41 patients with various forms of respiratory disease, out of a total of nearly 900 fiber endoscopies carried out directly under local anesthesia. It appears that the tissue samples obtained by biopsy with forceps are interpretable in almost all cases, that the result of biopsy is nil in sarcoidosis, low or limited, in cases of granuloma budding into the bronchial lumen as in tuberculosis. In bronchial carcinoma, the proof of malignancy was made in 65% of cases and the histological type determined in 52% of cases.
