NECROSIS: Necrotic wound of the foot
The death of cells, tissues, or organs. Necrosis may be caused by insufficient blood supply, pathogenic microorganisms, physical agents such as trauma or radiant energy (electricity, infrared, ultraviolet, roentgen, and radium rays), and chemical agents acting locally, acting internally after absorption, or placed into the wrong tissue. Some medicines cause necrosis if injected into the tissues rather than the vein, and some, such as iron dextran, cause necrosis if injected into areas other than deep muscle or vein.
