Keloids

A keloid is a type of hypertrophic scar. Keloids are made up of type I (and some type III) collagen that results in an overgrowth of tissue at the site of a healed skin injury. Keloids are firm, rubbery lesions or shiny, fibrous nodules and can vary from pink to flesh-colored or red to dark brown in color. A keloid scar is benign, non-contagious and usually accompanied by severe itchiness, sharp pains and changes in texture. In severe cases, it can affect movement of skin. Keloids expand in claw-like growths over normal skin. They have the capability to hurt with a needle-like pain or to itch without warning, although the degree of sensation varies from patient to patient.
