Necrosis (nek-ro' -sis) [vEnpuctq, from vsupdc, dead]. 

 The death of cells surrounded by living tissue. Necro- 

 sis proper refers to death in mass, necrobiosis to death 

 of individual cells. Among the causes of necrosis are : 

 (i) direct injury ; (2) obstruction of the circulation ; (3) 

 loss of trophic influence. The varieties of necrosis 

 are: (i) coagulative necrosis; (2) liquefactive necro- 

 sis ; (3) cheesy necrosis ; (4) dry and moist gangrene. 

 See Gangrene. Necrosed tissues may be absorbed, re- 

 tained, or thrown off. The dead tissue is called seques- 

 trum in case of bone, andsphacelus in case of soft parts. 

 In surgery the term necrosis is often applied specifically 

 to the death of bone. N., Anemic. See infarct. An- 

 emic. N., Caseous. See Cheesy. N., Balser's Fatty, 



the occurrence of areas of opaque whitish tissue often 

 seen surrounding the lobules of the pancreas in acute 

 pancreatitis, and also occurring in the omentum and 

 mesentery and in the abdominal fatty tissue generally. 

 They are usually about the size of a pin's head, but 

 may reach the size of a hen's egg. On section they 

 have a soft, tallowy consistence. They are constituted 

 of a combination of lime with certain fatty acids, 

 and may be encrusted with lime. They may occur 

 independently of disease of the pancreas. See Diseases, 

 Table of. N., Cheesy, necrosis characterized by 

 the formation of a cheese-like material. Dry and moist 

 cheesy necrosis are the two varieties described. It 

 is usually due to the presence of the tubercle-bacillus, 

 and is most often seen in the lungs. N., Coagulative, 

 a variety characterized by the formation of fibrin. Its 

 most common seat is the blood in thrombi. It also 

 occurs on mucous membranes, where it produces false 

 membrane, chiefly under the influence of the bacillus 

 of diphtheria, but also of other irritant agents. Occa- 

 sionally it occurs in the interior of organs as the result 

 of embolism or thrombosis, leading to the formation 

 of an anemic infarct q. v. N., Colliquative. 

 N, Liquefactive. N., Embolic, coagulative necrosis 

 in an anemic infarct following embolism. N., Hya- 

 line, coagulative necrosis ; also a synonym of hyaline 

 degeneration. N. infantilis. Synonym of Cancrum 

 oris. N. laryngis. Synonym of Perichondritis of the 

 Larynx. N., Liquefactive, a process analogous to 

 coagulative necrosis, but instead of fibrin the peculiar 

 reaction of fluids and cells gives rise to the formation 

 of a liquid. Blisters and vesicles, softening of the 

 brain subsequent to embolism, and suppuration are the 

 results of liquefactive necrosis. It may also be the 

 terminal stage of all other forms of necrosis. N., 

 Mercurial, a necrosis of bones due to chronic 

 poisoning with mercury. N., Phosphorus, a necro- 

 sis of bone, especially of the lower jaw, occurring in 

 those exposed to the fumes of phosphorus. N. of 

 the Teeth, odonto-necrosis. By the term necrosis, 

 when applied to the teeth, is meant the entire death 

 of the pulp and the loss of vitality of the peridental 

 membrane. N. ustilaginea, dry gangrene from 

 ergotism.
