[Pneumonia or drug-related exogenic allergic alveolitis? Key role of anamnesis in differential diagnosis].

A case is reported of an old female patient with exogenic allergic alveolitis which was first diagnosed as pneumonia progressing in the presence of long-term and intensive antibiotic treatment. Detailed analysis of the case history gave grounds for suspected drug-related exogenic allergic alveolitis. Discontinuation of antibiotics, administration of glucocorticoids and antiplatelet drugs led to recovery.
