Coagulative necrosis differs from other types of necrosis in several ways. In liquefactive necrosis, the tissue becomes liquid and structureless, often seen in brain infarctions and abscesses. Caseous necrosis is a combination of coagulative and liquefactive necrosis, commonly seen in tuberculosis, where the tissue appears cheese-like. Fat necrosis involves the saponification of fat in tissues like the pancreas and breast. Each type of necrosis has distinct histological features that aid in diagnosis.
