Chronic airway irritation

In chronic bronchitis, the atrophy of the mucosa gives it a tense and bright appearance, with wide glandular holes and sharp reliefs on the spurs and cartilages.

Multiple depressions of the bronchial mucosa in the right upper lobe, with anthracotic macules in them.

Dilated bronchial glands at the entrance of the left source bronchus, at the junction of its lateral wall with the posterior or mucous membrane.

Chronic bronchitis Forward displacement of the posterior wall of the right source bronchus during inspiration. The depth of the longitudinal folds is maintained and does not disappear, as occurs when the wall is “stretched” by extrinsic compression. Here the alteration is dynamic and is due to the flaccidity of the mucosa and the elastic bands.

Chronic bronchitis Thin secretion of mucous aspect in the left source bronchus.

On the right side wall there are several cartilaginous prominences that in some cases can acquire a triangular or “spur” shape. No pathological value.

Triangular aspect of the tracheal lumen, permanent deformation due to chronic cough.
