Dry gangrene is mostly seen at the ends of the limbs, for example, in atherosclerosis, thromboembolic vasculitis and frostbite. At this time, the arteries are blocked and the venous return is smooth, so the necrotic tissue has less water, plus the water on the surface of the body is easy to evaporate, resulting in the lesions being dry, solid and wrinkled, dark brown, with an obvious demarcation line between the surrounding healthy tissues. Since the necrotic tissue is drier, putrefactive bacterial infections are generally milder.
