Liquefactive action on necrotic tissue results in-
Correct Answer: Infarct
Description: infraction is the process of tissue necrosis usually coagulative type resulting from ischemia. In cerebral infract there is characteristic liquifactive necrosis. * Liquefactive necrosis is seen in focal bacterial or, occasionally, fungal infections, because microbes stimulate the accumulation of inflammatory cells and the enzymes of leukocytes digest ("liquefy") the tissue. For obscure reasons, hypoxic death of cells within the central nervous system often evokes liquefactive necrosis (Fig. 1-10). Whatever the pathogenesis, the dead cells are completely digested, transforming the tissue into a liquid viscous mass. Eventually, the digested tissue is removed by phagocytes. If the process was initiated by acute inflammation, as in a bacterial infection, the material is frequently creamy yellow and is called pus .ref Robbins 9/e p 10
