● Granulomatous disease of lungs in which almost all granulomas are centered in bronchi or bronchioles causing their destruction
● Immunologic reaction related to chronic eosinophilic pneumonia and allergic bronchopulmonary aspergillosis
● A histologic pattern of disease, not a specific diagnosis
● Usually adults, often with asthma history and limited to lungs, may be asymptomatic
● Usually solitary lesions that appear on chest X-ray as atelectasis or consolidation, not nodules
● Generally favorable prognosis
● Viscous material in involved bronchi
● Large and medium bronchi infiltrated by neutrophils, eosinophils and necrotic debris surrounded by foreign body giant cells
● Fragmented elastic tissue (with elastic stain)
● Also bronchiolitis obliterans
● No fibrinoid necrosis of vessels
● Wegener granulomatosis: kidney involvement, may also have bronchocentric granulomas
● Rheumatoid arthritis:
● Fungi: can identify orgqanisms with silver stain
● Cystic fibrosis: different clinical history
