Asthma. The airways typically show mucus plugging.
Asthma. Mucous plug with intraluminal inflammatory cells and hyperplasia of airway smooth muscle.
Asthma. The inflammatory cell infiltrate, predominantly eosinophils, extends focally into airspaces.
Bronchial wall shows increased numbers of bronchial glands characteristic of chronic bronchitis.
Chronic bronchitis shows bronchial surface epithelium with goblet cell metaplasia.

FIGURE 66.1. Photomicrographs of a sputum sample from an asthmatic patient. All of the micrographs were taken of unstained sputum samples pressed between a cover slip and a clear microscope slide. A sample was observed using the 40X objective and the 10X eyepiece. The final magnification of the micrographs is 1860X. (A) The broad arrow points to the brush border of a ciliated epithelial cell. Note the cell's apical nucleus and its pointed tail, which serves to fix the cell to the basement m...

FIG. 2.2. Pulmonary complications. A: Sublobar atelectasis. Asthmatic child with acute asthma attack. Note area of apparent consolidation in the right paratracheal region (arrows). This represents collapse of one portion of the right upper lobe. A subtler finding assisting interpretation is that the minor fissure is slightly elevated. B: Pneumomediastinum. Asthmatic child with pneumomediastinum with air surrounding the small triangular thymus gland (T), extending as linear sheaths into the ...
