This low-power photomicrograph of the lung shows: (1) markedly thickened pleura, indicating an inflammatory process which has been present for several days; (2) a small wedge-shaped segment of normal lung which is somewhat compressed due to artifact; (3) a large wedge-shaped segment of lung tissue with lobar pneumonia, which appears very dense due to extensive cellular infiltrate; and (4) a greatly thickened pleural space between these two lung lobes. This interlobar space is markedly thickened due to deposition of fibrinous exudate.

In alcoholics, aspiration pneumonia is common--bacteria enter the lung via aspiration of gastric contents.

An infiltrate is an accumulation of cells in the lung parenchyma--this is a sign of pneumonia.
