Figure 1

A case showing grade 1 alveolar septal capillary density (ASCD) (A and B) without any increase in endothelial cells in the alveolar septa (A: hematoxylin eosin stain; B: anti CD34 immunostain, ×200 original magnification). A case showing grade 2 ASCD (C and D) with a marked increase in endothelial cells (C: hematoxylin eosin stain; D: anti CD34 immunostain, ×200 original magnification).
