Allergic bronchopulmonary aspergillosis with marked peripheral blood eosinophilia and pulmonary eosinophilia: A case report

Figure 2 Hematoxylin-eosin-stained sections of lung tissue. A: Magnification × 20; B: Magnification × 40. The alveolar structure can be identified, the alveolar septum is slightly widened, and there are many eosinophils and a small amount of scattered lymphoplasmacytic infiltration in the alveolar septum and interstitium. A small amount of eosinophilic exudation can be seen in some alveolar spaces with no signs of necrosis. No typical granulomas or vasculitis is observed.
