Pneumosclerosis Dust

Pneumosclerosis is an inflammatory change in the lung tissue that is not associated with infection. This definition is surprising, since with the development of pneumosclerosis, the cause of changes is inflammation and tissue damage. After all, the word “pneumo...” in the name refers to inflammation. However, if we look at the classification of pneumosclerosis according to etiology (that is, the reasons for its occurrence), then everything is obvious: dust is the cause of fibrosis (sclerosation). Accordingly, the name “Dust pneumosclerosis” is actually the name of inflammation of lung tissue as a result of damage by dust particles. What happens to the lungs during inflammation? Why does pneumosclerosis occur?

Pneumosclerosis is one of the most common types of damage to the pulmonary parenchyma. It is based on an inflammatory reaction, tissue damage and their replacement with scar tissue, cell proliferation of altered tissue (cellular reproductive mechanism of tissue repair), collagen or fibrous restructuring of the bronchial wall, and the formation of pleural adhesions. In other words, with pneumosclerosis, lung tissue is replaced by connective (fibrous) tissue. The formation of fibrous tissue in the lung tissues is the effect of the sclerosing effect of all of the above reactions. The development mechanism is determined by the interaction of pulmonary inflammatory cells and the general human immune system, the cells of which can be specific (for example, in response to tuberculosis infection) or nonspecific (normally and in other forms of inflammation).

However, let's return to the name of the disease. In fact, we should use another name: “inflammatory changes in the pulmonary interstitium”, since along with areas of fibrosis in the lungs we usually see in
