Edema of the skin (lat. histericum) is a medical term used to describe a peculiar type of reddish-bluish spots that resemble bruises. However, unlike bodily bruises from bruises, these stains do not correspond to the properties of blood and arise independently without mechanical influence from the outside. The manifestation of this symptom becomes a frequent reason for patients to visit a general practitioner (dermatologist, allergist). Edema is an external manifestation of the disease as a whole.
Description of edema
Edema is an increase in tissue volume due to the release of fluid from the blood into their interstitial space. The tissues become denser and acquire a “waxy”, often hyperemic hue. The formation of dropsy occurs due to an increase in the concentration of plasma proteins in the bloodstream of peripheral vessels. Disruption of metabolic processes and the penetration of molecules responsible for blood clotting allows external changes to appear. These substances freely penetrate through the micropermeable membrane of the vascular wall into the interstitial fluid, causing edema. Swelling of the skin is caused by multiple factors.
