A deep tissue injury is an area of intact skin that has a purple or maroon discoloration from internal bleeding. It is an evolving injury that, if not managed correctly, will likely ulcerate and become a stage 3 or stage 4 pressure injury. This is not a stage 1 pressure injury, which are not characterized by deep purple or maroon discoloration, but rather has intact skin with non-blanchable redness. It is also not a stage 2 or 3 pressure injury because the skin is intact.
