title: Bronchocentric granulomatosis in a nonasthmatic patient without etiologic agent.
abstract: Bronchocentric granulomatosis (BG) is an uncommon pathologic finding characterized by necrotizing granulomas centered on bronchi and bronchioles. We report a nonasthmatic patient with a BG in whom no etiologic agent was identified. We discuss the different pathogenic mechanisms proposed in this group of patients.
