Skin graft. Image 3 of 3. Skin graft on a 56- year-old woman's leg, 6 weeks after grafting. Healing is nearly complete. Skin grafts are used when a wound is too large to be stitched shut or will scar severely if left to heal naturally. This patient wounded her leg in a fall. A layer of skin was taken from elsewhere on her body and placed over the wound. It has grown to meet the surrounding tissue, protecting the wound from infection. The colour and texture of grafted skin may not exactly match its surroundings, even when healing is fully completed. For this wound 7 days and 16 days post-graft, see images M336/052 and M336/051 respectively.
