A Keloid is the formation of a type of scar which, depending on its maturity. It is a result of an overgrowth of granulation tissue at the site of a healed skin injury which is then slowly replaced by collagen. Keloids are firm, rubbery lesions or shiny, fibrous nodules, and can vary from pink to the colour of the patient's flesh or red to dark brown in color. A keloid scar is benign and not contagious, but sometimes accompanied by severe itchiness, pain, and changes in texture. In severe cases, it can affect movement of skin. Keloid scars are seen 15 times more frequently in highly pigmented ethnic groups than in Caucasians.
