title: [Practice relevant aspects of immunohistochemistry in pulmonology].
abstract: Own experiences in practical application of immunohistochemistry are demonstrated in cases of lung fibrosis, sarcoidosis, tuberculosis and allergic vasculitis. Methods for demonstration of immunoglobulins (IgG, IgE) are useful in diagnosis of allergic vasculitis (IgG) and allergic alveolitis (IgE). Lysozyme is an important morphological parameter for the estimation of the activity of sarcoidosis. First results of application of antisera against mycobacteria and Kveim antigen are discussed in respect to more precise differential diagnosis of granulomatous lung diseases (sarcoidosis, tuberculosis).
