Chronic obstructive pulmonary disease (COPD) is a group of lung diseases. Gross and microscopic evaluation of an 80 y.o. male cadaver showed that the left lung had dilated air spaces and showed notable alveolar wall destruction and dilated airspaces. The right lung was dense and firm, containing macrophages laden with anthracotic pigment and alveoli filled with red blood cells and fibrin. Anthracotic pigment in the lungs indicates long-term exposure to airborne pollutants (e.g. smoke, dust). This profile is aligned with the typical presentation of COPD and demonstrates the risk of comorbid infection with the presence of an organizing pneumonia.
