Bronchial asthma (asthma bronchiale) 40x

Histologically mucus is seen in the lumens of the bronchi, which contains eosinophils and exfoliated columnar epithelial cells. Mucus and tissue are forming vertical structures, so called ‚ÄúCurschmann’s spirals” (*). The basement membrane of epithelium in the bronchi has become thicker. In the submucosa there is inflammatory cell infiltration, especially eosinophils. The amount of glands secreting mucus in submucosa has increased and smooth muscle walls in the bronchi are hypertrophied (#). 40x magnification, HE-staining.
