[Some particularities in diagnostic, clinical picture, and therapy of pulmonary sarcoidosis (author's transl)].

Serological reactions (indirect hemagglutination and complement-fixing reaction) are used for differentiation of pulmonary sarcoidosis from tuberculosis. Antituberculous antibodies were found in tuberculosis in 83%, in sarcoidosis only in 22%. Pulmonary sarcoidosis is found more often in females than males (60:40). It is most frequent between 20 to 40 years (82%). Stadium I was present in 76.5%. Stadium II in 14.7% and Stadium III in 8.8% of all cases. Extrapulmonary lesions were observed in 8% of all cases of pulmonary sarcoidosis. Tuberculin reaction was negative in 93%. Mediastinoscopy proved to be the best method for bioptic examination (100%). The clinical signs are discussed.
