DIC results in depletion of the body's clotting resources, so that it can no longer control bleeding. Consequently, the unclotted blood bleeds into the skin and other organs, leading to red or black patchy rash and to hematemesis (vomiting blood) or hemoptysis (spitting blood). The rash may cause bumps on the skin that look somewhat like insect bites, usually red, sometimes white in the center.
