What is Keloid or Keloid Scar or Cheloidچوٹ کے بعد بننے والی گلٹی
Keloids can be considered to be "scars that don't know when to stop."
A keloid, sometimes referred to as a keloid scar, is a tough heaped-up scar that rises quite abruptly above the rest of the skin. It usually has a smooth top and a pink or purple color. Keloids are irregularly shaped and tend to enlarge progressively. Unlike scars, keloids do not subside over time. These may itch and be painful, and some keloids can grow to be quite large.
Keloids are overgrowths of fibrous tissue or scars that can occur after an injury to the skin. In individuals prone to keloids, even minor traumas to the skin, such as ear piercing, can cause keloids. Keloids can occur anywhere on the body, but they are most common on the earlobes, upper back, shoulders, and chest.
Keloids should not be confused with hypertrophic scars, which are raised scars that do not grow beyond the boundaries of the original wound.
Keloids are equally common in women and men, although at least in times past more women developed them because of a greater degree of earlobe and body piercing among women. Keloids are less common in children and the elderly.
Causes of Keloid or Keloid Scar or Cheloid
Keloids may occur from various skin injuries as surgical incisions, traumatic wounds, vaccination sites, burns, and chickenpox.
Wounds that are under tension while healing, or which get infected, are particularly likely to form keloids, as are burn and acne scars.
If someone in your family has keloids then you are at increased risk of get affected by it.
One another main cause of keloid is skin trauma i.e. skin or muscle tension (the upper arm and back) seem to contribute to keloid formation.
Exposure to the sun is also responsible in the formation of keloid.
A deficiency or an excess in melanocyte hormone (MSH), decreased percentages of mature collagen and increased soluble collagen, are among the main causes of keloid.
Keloid's formation may be due to the piercing of body parts, such as the earlobes and abdomen.
Dark skinned people get keloids much more easily than those with a paler skin. They are especially common in people with black skin.
