fat necrosis

fat necrosis
a condition in which the neutral fats in the cells of adipose tissue are split by enzymatic action into fatty acids and glycerol, producing minute, chalky white areas where the released fatty acids react with calcium, magnesium, and sodium ions to form soaps; it usually affects the pancreas and peripancreatic fat in acute hemorrhagic pancreatitis. Called also steatonecrosis.
