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 ...
Necrosis can also result from chemical trauma, with alkaline and acidic compounds causing liquefactive and coagulative necrosis, respectively, in affected tissues. The severity of such cases varies significantly based on multiple factors, including the compound concentration, type of tissue affected, and the extent of chemical exposure.
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 ]

Necrosis begins after 20 minutes of an infarction. Under 4 hours of ischemia, there are no gross or microscopic changes noted. [2] From 4-24 hours coagulative necrosis begins to be seen, which is characterized by the removal of dead cardiomyocytes through heterolysis and the nucleus through karyorrhexis, karyolysis, and pyknosis. [3]
Karyolysis is the culminating step in the process of necrosis. Necrosis is a form of cellular injury in which living tissue experiences irreversible damage through premature cell death. While both are forms of cell death, necrosis differs from apoptosis as an external factor triggers necrosis rather than it being a controlled and planned process.
It is considered a type of cellular necrosis. [1] Two types of myocytolysis have been defined: coagulative and colliquative. [1] [2] [3] Coagulative myocytolysis appears in the myocardium near areas of coagulative necrosis or areas affected by myocardial infarction. [2]
Necrosis [ edit ] The stages of cellular necrosis include pyknosis , the clumping of chromosomes and shrinking of the nucleus of the cell ; karyorrhexis , the fragmentation of the nucleus and break up of the chromatin into unstructured granules; and karyolysis , the dissolution of the cell nucleus.
