[Possibilities of instrumental biopsy methods in the diagnosis of rarely occurring disseminated processes of the lungs].

Fifty eight patients with disseminated lung lesions were investigated, including 19 with histiocytosis X, 5 with alveolar microlithiasis, 8 with pulmonary phospholipoproteinosis, 16 with idiopathic hemosiderosis, 1 with primary pulmonary amyloidosis and 9 with primary diffusive tumors of the lungs. In all the above cases, a complex bronchological examination was undertaken with the use of different biopsy transbronchial procedures as well as an open biopsy of a lung. Diagnostic value and efficiency of bronchobiopsies were considered. Recommendations concerning the use of different instrumental techniques were formulated.
