Definition of Skin graft

Skin graft: Skin used to cover an area where the patient's skin has been lost due to a burn, an injury, or surgery. The most effective skin grafts involve moving the patient's own skin from one part of the body to another. The second most effective type are skin grafts between identical twins. Beyond these two procedures, there is a strong chance that the body will reject the new skin, although the graft may protect the body and give the body time to grow new skin of its own.
