Dry gangrene is when the tissue becomes dyhydrated and shrinks back and becomes dark

In dry gangrene the affected tissue becomes dry and shrinks, the skin wrinkles, and its color
changes to dark brown or black. The spread of dry gangrene is slow. It results from a cut off in
arterial blood supply and is a form of coagulation necrosis. In wet gangrene, the affected area
is cold, swollen, and pulseless. The skin is moist, black, and under tension. Blebs form on the
surface, liquefaction occurs, and a foul odor is caused by bacterial action. The spread of
tissue damage is rapid.
