Keloid Scar at 20x Magnification

Although a keloid may result after any trauma to the skin, including piercing of the earlobes, surgical incisions, tattoos, acne, and chicken pox, scientists have not yet discovered exactly why the overgrown scar occurs rather than a normal one. Evidence suggests, however, that there may be a genetic element involved since some families have a history of keloid growth and the scars are most prevalent in members of certain races, namely individuals of African or Asian descent. Keloids are not usually painful, but can cause some discomfort depending on where they are located and may be itchy or tender to the touch. If the scar is situated on skin above a joint, some limitation to movement may occur as well. The primary concern for most individuals with keloids is of a cosmetic nature.
