When seeing pigmented macrophages of the lung, categorize as follows:

Disease Macrophages Pigment appearance (HE stain) Associated medical history Image Image comment
Anthracosis Black-brown
  • Age and urban dwelling.[1]
  • Coal workers[2]
Histopathology of anthracotic macrophage in lung, annotated.jpg Black arrow shows interstitial anthracotic pigment. Nearby macrophages (white arrow) can be presumed to contain anthracotic pigment. Reporting is optional in mild cases in the elderly.
Respiratory bronchiolitis "Smoker's macrophages" Yellow to light brown and finely granular[3] Tobacco smoking Histopathology of respiratory bronchiolitis.jpg Smoker's macrophages (arrow); mild interstitial lymphocytic infiltrate and mild fibrosis (arrowhead)[4]
Heart failure Siderophages Brown granules[5]
  • Heart failure
  • Pulmonary hemorrhage
Histopathology of pulmonary congestion and siderophages.jpg This case also shows vascular congestion.
