[CROHN'S DISEASE. TO THE 90th ANNIVERSARY OF THE DESCRIPTION].

The article describes the main achievements in the study of Crohn's disease, first described as a disease of the terminal ileum, affecting mainly young people, characterized by subacute or chronic necrotizing and scarring inflammation. In subsequent years, the inflammatory disease was also detected in other parts of the gastrointestinal tract. This disease affects the entire intestine and can involve every part of the gastrointestinal tract, from the mouth to the anus. The history of the study of Crohn's disease for 90 years has made it possible to delve deeply into the pathogenesis of inflammation, but has not yet come closer to revealing its etiology. Therefore, it is impossible to talk about the possibility of recovery from CD.
