Histopathologic findings of bronchoscopic biopsy specimens after stratification on HRCT pattern.

HRCT pattern	Histopathology by bronchial biopsy
Isolated airways disease (n =4)	Lymphoplasmacytic inflammation with bronchial inflammation Lymphoplasmacytic inflammation (transbronchial) Granulomata (transbronchial) Inflammation with eosinophils
Isolated ILD (n =2)	Cellular bronchiolitis with granulomata (transbronchial)
Isolated ILD (n =2)	Minimal chronic inflammation
Airways disease and ILD (n =4)	Eosinophilic and lymphoplasmacytic inflammation Chronic inflammation (transbronchial) Chronic inflammation Chronic inflammation

HRCT=high resolution computed tomography, and ILD=interstitial lung disease.
