The accumulated experience and the literature data allow for the separation of a group of granulomatous pulmonary diseases among pulmonary diseases of different etiology. Etiologically heterogeneous granulomatous diseases are united by the general signs: granuloma development, immunologic disturbances mainly within the cellular system and mediators as well as systemic vascular affection in the form of vasculitis. In our opinion, granulomatous diseases include disseminated tuberculosis, sarcoidosis of respiratory organs, exogenic and idiopathic fibrous alveolitis, Wegener's granulomatosis, histiocytosis X, primary hemosiderosis, Goodpasture's syndrome and some other rare diseases. Granulomatous diseases are diagnosed on the basis of the ++clinico-roentgenologic findings with an obligatory cytological and histological study of the bioptic specimen; immunologic diseases are diagnosed proceeding from the study of the immunologic status and detection of specific antibodies; of great significance for the diagnosis of pulmonary granuloma caused by infectious pathogens are microbiologic studies which provide for the detection of microorganisms and fungi. Study of the clinicoroentgenologic and laboratory data made it possible to distinguish a number of features typical for each disease and to unite them into diagnostic symptom complexes. Despite the different course of granulomatous pulmonary diseases they may end in recovery and granuloma resolution, development of lung fibrosis in a chronic course and in certain diseases in lung tissue destruction with cavity formation (tuberculosis, Wegener's granulomatosis). A fatal outcome may also ensue due to an acute or chronic course of the diseases.
