Plate I The respiratory bronchiolar wall is thickened with lymphocytic infiltration. The bronchiolar lumen is obliterated by a purulent plug. Small polypoid granulation tissues are seen at the junction of the respiratory and alveolar duct. Marked anthracosis and slight foam cell accumulation are observed in the peribronchiolar interstitium. No remarkable change is noted in the alveolar wall. (HE, magnification x 26.4)

Plate 2 A polypoid granulation tissue is formed in the constricted lumen of the respiratory bronchiole. Marked foam cell accumulation is seen in the peribronchiolar interstitium and associated with centrilobular emphysema. (HE, magnification x 32)
