Emphysema (Panacinar)
Gross photos of emphysematous lungs as seen on cut surfaces are shown. These overexpanded lungs would take
up a lot of space in the thorax. In panacinar emphysema, as shownNoca in both of these photos, the expansion is
diffuse throughout each affected acinus, involving respiratory bronchiole, alveolar ducts, and terminal alveoli.
In centriacinar (centrilobular) emphysema, the gross changes are less severe; the overexpansion is mostly
confined to the respiratory bronchioles in the central portion of the acinus.
