Pulmonary tuberculosis and bronchocentric granulomatosis.
Bronchocentric granulomatosis (BG) is an uncommon inflammatory lesion of unknown etiology defined on morphologic grounds by the presence of necrotizing granulomata centered on bronchi and bronchioles. We report the typical pathologic features of BG in a patient with tuberculosis. Mycobacterial and other types of infection should be excluded by appropriate stains and cultures in all patients with BG on lung biopsy, especially those who are nonasthmatic.
