File:IPLab1LungAbscess1.jpg|This is a gross photograph of the lungs from this case. Note the abscesses (arrows) especially in the lower lobes. The entire lung is consolidated.

File:IPLab1LungAbscess2.jpg|This is a closer view of the lung from this case. In this section of upper lobe there are multiple areas of early abscess formation (arrows). Note the circumscribed whitish-tan lesions. These lesions are filled with white blood cells.

File:IPLab1LungAbscess3.jpg|This low-power photomicrograph of lung from this case demonstrates one of the abscesses (arrows). Note that the material inside the abscess has been ~~expelled.~~

File:IPLab1LungAbscess3.jpg|This low-power photomicrograph of lung from this case demonstrates one of the abscesses (arrows). Note that the material inside the abscess has been degraded and removed. Note the loose necrotic material inside the abscess. This material is made up of inflammatory cells (primarily dead white blood cells) and necrotic lung tissue.

~~File:IPLab1LungAbscess4.jpg|This higher-power photomicrograph of lung demonstrates the edge of the abscess~~. Note the ~~loss of~~ material ~~from the center of~~ the abscess ~~(1) and loose necrotic material that has not been expelled (2)~~. This material is made up of inflammatory cells (primarily dead white blood cells) and necrotic lung tissue.

File:IPLab1LungAbscess5.jpg|This is a low-power photomicrograph of lung tissue containing a large abscess. The center of the abscess contains necrotic debris (1) and there is a rim of viable inflammatory cells (arrows) surrounding this abscess.

File:IPLab1LungAbscess6.jpg|This high-power photomicrograph demonstrates a small abscess (arrow) with a necrotic center.

File:~~IPLab1LungAbscess7~~.jpg|This high-power photomicrograph shows the center of ~~an abscess containing neutrophils and necrotic debris.~~

File:IPLab1LungAbscess8.jpg|This high-power photomicrograph shows the center of this abscess which contains inflammatory cells (primarily neutrophils) (arrows). There is a bacterial colony in the center of this abscess (1).

~~File:IPLab1LungAbscess8.jpg|A high-power photomicrograph of lung from~~ this ~~case demonstrates a small~~ abscess ~~full of~~ inflammatory cells (primarily neutrophils) (arrows). There is a bacterial colony in the center of this abscess (1).
