MODEL RELEASED. Keloid scar on the chest of a 11 year old boy after surgery to implant a heart pacemaker. A keloid scar is a scar that fills with the skin protein collagen. In a normal scar the collagen breaks down once the wound has healed,but this fails to happen during the formation of a keloid scar. The scar expands from its original boundaries,and continues to grow even after the wound has healed. A pacemaker is a device that supplies electrical impulses to a faulty heart,so that it beats normally | |
