title: [Pulmonary biopsy in interstitial pneumopathies].
abstract: 1119 pulmonary biopsies (two thirds open) have been performed in 108 patients with signs of diffuse interstitial disease of the lung. The results showed 29 cases of fibrosing alveolitis, 4 of granulomatous alveolitis, 8 of diffuse interstitial fibrosis, 12 of eosinophilic granuloma, 12 of pneumoconiosis, 16 of sarcoidosis, and 38 with other pulmonary lesions. Biopsy via thoracotomy is the best diagnostic technique, with a 97.4% yield; with transparietal biopsies the yield is 81% and with transbronchial biopsies 60%. Histology permits exact diagnosis in all pneumopathies except fibrosing alveolitis. In this case the pathologist guides the clinician's investigations towards a search for an allergic etiology.
