Totally different: A bruise is the result of trauma to the skin region where slight bleeding occurs and a ill defined hemorrhagic area results that appears as what is know as a bruise. A result is that there is usually tenderness in the area. Gangrene is loss of blood supply to the tissue which causes death of the involved tissue and blackening of the dead tissue with loss of warmth and associated vascular pulse
