Figures & data
Figure 1 Lung histology obtained from a patient who had died during a COPD exacerbation [pictures from Ref. Citation[44]]. Left: The lumen of a terminal bronchiole showing mucus admixed with scattered inflammatory cells and desquamated epithelial cells. Focally, the mucosal layer shows basal cell hyperplasia and (arrow) mucosal lining by mucin-producing cells (hematoxylin-eosin, original × 400). Right: A respiratory bronchiole with luminal accumulation of mucus admixed with desquamated cells and inflammatory cells. The alveolar septa show vascular congestion and increased numbers of acute inflammatory cells (arrows) (pentachrome, original × 400).
