File:IPLab3Bronchopneumonia7.jpg|This higher-power photomicrograph shows a central portion of an abscess. Note the absence of any parenchymal lung tissue in this section due to extensive neutrophilic infiltration with liquefaction necrosis of the parenchymal tissue. Masses of leukocytes (primarily neutrophils), fluid ("liquor puris" which is serum, fibrin, etc.), and necrotic debris within an abscess form what is referred to as "purulent material" -- or "pus" in lay terminology. The blue-staining mass in the center of this abscess (arrow) represents colonies of bacteria.

Study Questions
* <spoiler text="What does it mean to have a shift to the left?">A "shift to the left" indicates an increased ratio of immature PMNs ("bands") to mature PMNs ("segs") within the peripheral circulation.</spoiler>
* <spoiler text="Is there destruction of lung parenchyma in bronchopneumonia?">Yes, there is usually destruction of alveoli and, in this case, there are abscesses containing bacteria.</spoiler>
* <spoiler text="How would this lung have healed if the patient had survived?">Scar tissue would form in the areas of tissue destruction (abscesses).</spoiler>
