1. Cyst of Bronchogenic origin (from Latin) - a type of benign formation located in the area of the respiratory organs. They are formed with the development of the respiratory system and in early childhood they appear as sacs filled with a jelly-like substance or reverse air. As the child grows older, the cysts disappear, which serves as an indicator of the formation of the respiratory apparatus at the required level. In the case of a pathological structure, they can pose a health threat, including rupture.
