[Our experience in bronchiolitis obliterans organising pneumonia (BOOP): personal experience].

BOOP is a disease with characteristic histology features which can occur as a secondary lung reaction to the various toxic agents or as a primary idiopathic disease. Idiopathic form of BOOP is a rare disease and may be found in 6-7 patients of 100,000 hospital admissions. We described 3 patients with idiopathic BOOP confirmed by the histologic lung examination. The time from the beginning of symptoms till the microscopical diagnosis ranged from 6 to 12 months. At the beginning of the disease the patients had symptoms compatible with the respiratory infection. In one of the patients the clinical course of the disease had a progressive character. In two patients spontaneous regression of radiological lung lesions was observed. This regression was however only temporary in one of them. In two cases treated by steroids regression of lung lesions was noticed.
