OH is a nonspecific chronic inflammatory skin lesion in newborns. Mostly occurs in premature babies. In the malignant form, the disease can lead to the death of the child. The disease develops against the background of a weak immune system, at the stage of transition of birth material from the mother’s birth canal to the body of the newborn child on the surface of his skin. That is, this process occurs specifically in children up to seven days of age. The inflammatory process is focal in nature, affecting the superficial layers of the dermis of the skin, subcutaneous fatty tissue and deep soft tissues. The reasons may be: mechanical damage as a result of various manipulations, infectious agents, allergic reactions and much more.
