Apoptosis vs. Necrosis

Apoptosis (―dropping off‖) is an important distinct type of cell death that differs from necrosis

in several ways. Apoptosis is an active process of cellular self-destruction called programmed

cell death and is implicated in both normal and pathologic tissue changes

Necrosis--Cellular death eventually leads to cellular dissolution, or necrosis. Necrosis is the

sum of cellular changes after local cell death and the process of cellular self-digestion, known as

autodigestion or autolysis

Types of Necrosis (liquefactive, coagulative, fat, gas gangrene, dry gangrene, wet gangrene

caseous)

Dry gangrene: Slow spreading, tissue becomes dry, brown or black, it shrinks and wrinkles.

Wet gangrene: Area is cold, swollen, pulseless, moist, black and a foul odor production

Coagulative necrosis. Occurs primarily in the kidneys, heart, and adrenal glands; commonly

results from hypoxia caused by severe 103ischemia or hypoxia caused by chemical injury,

especially ingestion of mercuric chloride. Coagulation is a result of protein denaturation, which

causes the protein albumin to change from a gelatinous, transparent state to a firm, opaque state

.The area of coagulative necrosis is called an infarct.
