The causes of the formation of keloid scars have so far not been identified by doctors. Among the most likely factors leading to the formation of keloid tissue at the wound healing site, include:
– Reduced tissue immunity,
– Genetic predisposition;
– Features of the epidermis;
– Infection of the wound during healing.
Keloid scars are a convex tissue outgrowth at the site of wound healing. The surface of the outgrowth is often elastic, uneven, considerably protruding above the surface of the skin. Often the keloid differs from the usual skin and color. In appearance, the keloid scars resemble a greatly enlarged irregularly shaped wart and represent a significant cosmetic defect. At the same time, the growth of the outer, visible part of the keloid scar can continue for several years after wound healing.
However, keloid scars are not only a cosmetic defect, but also soreness in the scar, itching and burning, tightness and increased sensitivity of the keloid tissue to tactile influences. Self-keloid scars do not resolve. Moreover, in some cases even a few years after the damage of the skin, the scar can begin to form clawlike outgrowths, occupying an ever larger surface of the skin. Most susceptible to the formation of keloid scars of the ear, chest, neck and face. And most often keloid scars are formed after such types of skin damage as burns.
Keloid scars are treated with increased pressure on damaged tissues. This pressure is created by wearing a tight bandage for several months. However, this method is not always effective. Therefore, in a number of cases, hormone therapy is used to treat keloid scars. It should also be noted that in the presence of keloid scars on the skin, dermatologists, in order to avoid the growth of abnormal keloid tissue, recommend to abandon massage, solarium and beach, sauna, hot tubs and other thermal procedures.
