Pathological changes in chronic obstructive pulmonary disease Pathological changes in chronic obstructive pulmonary disease. a) Characteristic picture of airways changes, with increase of goblet cells, a thickened airway wall with some adventitial inflammation, and a small lymphoid follicle at the left upper side. Pathological changes in chronic obstructive pulmonary disease. a) Characteristic picture of airways changes, with increase of goblet cells, a thickened airway wall with some adventitial inflammation, and a small lymphoid follicle at the left upper side. Emphysema is hardly present here. Haematoxylin and eosin, ×200 magnification, scale bar=200 μm. Inset shows magnification of part of the airway with a lymphoid follicle; scale bar=50 μm. b) At the left, an almost longitudinal cross-section of a small airway, and at the right, severe parenchymal destruction by emphysema.
