Findings in the Dissection Lab
blebs (air pockets) are characteristic of chronic obstructive pulmonary
disease (COPD, emphysema). However, they are also seen in lungs that are
otherwise normal in appearance. In this case only a small part of an otherwise
healthy lung displays a bleb, or air pocket, in the lung tissue. It was
likely caused by some previous disease process that produced localized
disruption of the lung tissue.
