Hemosiderin-Laden Macrophages in Bronchoalveolar Lavage: Predictive Role for Acute Exacerbation of Idiopathic Interstitial Pneumonias

Figure 3

Histological findings of nonspecific interstitial pneumonia with a higher hemosiderin score. Aggregation of pigmented macrophages in alveolar spaces (circles) and capillary multiplication (arrow heads) was shown (Hematoxylin–Eosin staining).
