Keloid scar on the forearm of a 57-year-old male patient following an operation to remove part of the radial artery from the arm. The artery was collected for use in a coronary artery bypass graft (CABG) operation. Keloid scars are made of a hard and irregular type of scar tissue, which continues to grow even after the wound has healed. They often form where an injury, burn or surgical incision is put under tension. Some individuals are much more prone to keloid scarring than others. In their early stages, keloid scars may respond to strong local steroids, compression or cryotherapy, but treatment is usually by re-excision and radiotherapy.
