Liquefactive necrosis is most commonly seen in which tissues?

Liquefactive necrosis happens when enzymatic digestion turns dead tissue into a liquid mass. This is especially likely in the brain and in abscess centers because of the high lipid content and the abundant lysosomal enzymes released by microglia in the brain and by neutrophils in pus, respectively. In the brain, myelin-derived lipids and active microglial enzymes rapidly digest dying neural tissue, creating a liquefied area that can cavitate over time. In abscesses, infiltrating neutrophils release hydrolytic enzymes that break down surrounding tissue, producing a pus-filled, liquefied center. Other tissues more commonly undergo coagulative necrosis after ischemia (where the architecture is preserved for a time), such as heart muscle after infarct, while liver injury often leads to regeneration rather than straightforward liquefaction. Hence, brain tissue and abscess centers are the classic sites for liquefactive necrosis.
