Liquefactive necrosis (or colliquative necrosis) is a type of necrosis which results in a transformation of the tissue into a liquid viscous mass. [1] Often it is associated with focal bacterial or fungal infections, and can also manifest as one of the symptoms of an internal chemical burn . [ 2 ]
Coagulative necrosis can be induced for treatments of cancers. Radiofrequency (RF) energy can be used in liver resection surgeries to produce coagulative necrosis, creating a coagulative necrosis zone. This coagulates the liver resection margins and is useful in liver resection surgeries for helping to stop bleeding within the resection margin ...
Gangrenous necrosis can be considered a type of coagulative necrosis that resembles mummified tissue. It is characteristic of ischemia of lower limb and the gastrointestinal tracts. Both dry gangrene and gas gangrene can lead to this type of necrosis. If superimposed infection of dead tissues occurs, then liquefactive necrosis ensues (wet ...
English: Histopathology of a pheochromocytoma with coagulative necrosis, displayed at gross pathology (upper left) and light microscopy at low (upper right), medium (lower left) and high magnification (lower right). High magnification reveals ghost cells.
Ischemic coagulative necrosis results and fibrosis of the affected area develops from the reparative response beginning at the preserved margins and working its way inwards. One exception to coagulative necrosis is the brain, which undergoes liquefactive necrosis in response to infarction. [citation needed]
Cell damage (also known as cell injury) is a variety of changes of stress that a cell suffers due to external as well as internal environmental changes. Amongst other causes, this can be due to physical, chemical, infectious, biological, nutritional or immunological factors.
Coagulative myocytolysis appears in the myocardium near areas of coagulative necrosis or areas affected by myocardial infarction. [2] This phenomenon tends to occur when neighboring cardiac muscle loses its ability to contract (i.e. in ischemia or infarction ). [ 2 ]
Nontumoral adrenal gland in the right lower corner, and well-encapsulated tumor in the remainder of the photograph (b). The tumor had a large area of coagulative necrosis in the center. The necrotic material contained morphologically ghost cells (d, e) and was immunohistochemically markedly positive for chromogranin A (c, g, h).
