Acute inflammatory lung injury of types 1 (a-c) and type 2 (d). a The exudative phase of diffuse alveolar damage with a hyaline membrane with neutrophils accumulation in alveolar septa and air spaces. b Alveolar epithelial cells absent from alveoli (arrow) and cytokeratin positive cell debris in air spaces. c Accumulation of platelets mostly in the capillaries of the alveolar septa. d Mild congestion, edema and extravasation with neutrophils accumulation in alveolar septa and air spaces. Scale bars: 30 μm (a-d). Immunohistochemistry for AE1/AE3 (b) and CD42b (c)
