Histopathology of<unk> , showing neutrophils filling a bronchiole.<unk>  may sometimes be diagnosed after death, during autopsy. On gross pathology there are typically multiple foci of consolidation present in the basal lobes of the human lung, often bilateral. These lesions are 2–4 cm in diameter, grey-yellow, dry, often centered on a bronchiole, poorly delimited, and with the tendency to confluence, especially in children. Light microscopy typically shows neutrophils in bronchi, bronchioles and adjacent alveolar spaces.
