Slide 2 (117)
Low power microscopic: The alveoli show a uniform infiltration of neutrophils. The pleura shows anthracosis and chronic fibrosis perhaps related to a previous episode of pneumonia. Note that all alveoli show the same stage of pneumonic infiltration and compare this with bronchopneumonia.
