A IV 9 lobular bronchopneumonia HE further information (German) on HiPaKu 
  ICD-10: J18.0
 
   
83-year-old female had a stroke with hemiplegia 2 months prior to passing away (specimen from autopsy).

 
- Lung architecture maintained.
- Dense accumulation of neutrophilic granulocytes in some peripheral bronchi (acute bronchitis).
- Congestion of septal capillaries.
- Extensive exudation of neutrophilic granulocytes and fibrin into large alveolar groups around bronchi and bronchioli. Patchy consolidation of the lung is characteristic of lobular bronchopneumonia. In contrast, lobar pneumonia leads to uniform consolidation of a large part of a lobe or of an entire lobe of the lung
- A mainly fibrinous pleuritis is observed in the interlobar fissure.

 
Bronchopneumonia arises frequently in bedridden patients.
