​What is Pathology - Give a few examples of necrosis that is liquefactive. 
Brain infarct: The necrotic area softens (encephalomalacia), and macrophages phagocytize the necrotic tissue debris. Diffusion of fluid from the surrounding interstitial spaces of the brain fills the residual void ("the body abhors a vacuum"). A fluid-filled pseudocyst like this can last indefinitely. 
Abscess: This is caused by a purulent infection that is localised. It usually manifests as a pus-filled cavity, which is made up of liquefied tissue from the diseased organ infiltrated by dead and dying neutrophils. 
Wet gangrene of the extremities: This is a type of coagulative necrosis with a bacterial infection that is commonly found in diabetic individuals. Bacterial lytic enzymes break down the tissue, causing it to liquefy.
