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.

acute esophageal necrosis

Necrotizing esophagitis.

Acute damage to the renal tubules; usually due to ischemia associated with shock.

central necrosis

dry necrosis

Dry gangrene.

embolic necrosis

Necrosis due to an embolic occlusion of an artery.

fat necrosis

Necrosis of fatty tissues, seen, for example, in patients with severe cases of pancreatitis.

fibrinous necrosis

Coagulation necrosis.

focal necrosis

Necrosis in small scattered areas, often seen in infection.

Necrosis forming a dry rubbery mass resulting from syphilis.

ischemic necrosis

liquefactive necrosis

Colliquative necrosis.

medial necrosis

Necrosis of cells in the tunica media of an artery.

moist necrosis

Necrosis with softening and wetness of the dead tissue.

postpartum pituitary necrosis

Sheehan syndrome.

putrefactive necrosis

Necrosis due to bacterial decomposition.

Necrosis caused by radiation exposure.

subcutaneous fat necrosis of newborn

An inflammatory disorder of unknown cause affecting fat tissue that may occur in the newborn at the site of application of forceps during delivery and occasionally in premature infants.

superficial necrosis

Necrosis affecting only the outer layers of bone or any tissue.
