Slide 72: Lung with healed pleuritis

||The thickening of the
pleura is quite striking here. What do you make of the pigmented material
in this section?

||This slide shows a
profoundly thickened and scarred pleural surface. This is the end stage of
a pleuritis and is likely years old. The original pleuritis probably was
the result of a bacterial pneumonia. Observe the highly collagenized scar
tissue with a relative paucity of inflammatory infiltrate. This scarred pleura
very likely produced an impairment in chest wall expansion and thereby probably
had an effect on pulmonary function. Also note the lung tissue adjacent to
the scarred pleura. The air sacks are enlarged and there is some interstitial
fibrosis as well. These are representative changes of emphysema.
