[The tobacco grower's lung: x-ray variants].

In 143 persons professionally involved with the growing and processing of tobacco roentgenologic lung examinations were carried out. The detected diseases of the respiratory system were classified as exogenous allergic alveolitis (EAA), tobacco growers disease. The proven roentgenologic lung changes were grouped in roentgenologic symptom complexes, that correlate with the clinical variations of the disease (obstructive bronchitis, bronchial asthma, recurring pneumonia).
