Necrosis
In liquefaction necrosis the dominant factor is the effect of hydrolytic lysosomal enzymes. The end result is a local accumulation of protein-rich, semifluid material. It is not particularly common as a primary event except in the brain. However, if necrotic tissue becomes secondarily infected by pus-forming organisms, liquefaction commonly takes place.
