Definition / general
  • 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 Xray as atelectasis or consolidation, not nodules
  • Generally favorable prognosis
Gross description
  • Viscous material in involved bronchi
Microscopic (histologic) description
  • 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
