Keloid scar. Close-up of a red keloid scar seen on the skin of a 19 year-old female patient. 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 healing injuries, burns or surgical incisions are put under tension. Some individuals are much more prone to keloid scarring than others. It tends to occur in some families and is much more common in black people. In their early stages, keloid scars may respond to strong local steroids or to compression or cryotherapy, but treatment is usually by re- excision and radiotherapy.
