Bronchiectasis in the aged.
نویسنده
چکیده
Examination of the diseased bronchi reveals the loss of normal columnar ciliated epithelium. This is replaced in some cases by purely cicatricial tissue, and in others by stratified squamous cell epithelium. The basement membrane of the mucosa is likewise destroyed or damaged with disappearance of the elastic tissue fibers. The submucosa becomes densely fibrotic and rigid. In the vicinity of the lung parenchyma there appears to be laid down additional fibrosis which adds to the thickness and rigidity of the bronchial wall.
