Fat necrosis is a form of necrosis characterized by the action upon fat by digestive enzymes.[1]
In fat necrosis the enzyme lipase releases fatty acids from triglycerides. The fatty acids then complex with calcium to form soaps. These soaps appear as white chalky deposits.[2]
It is usually associated with trauma of the pancreas or acute pancreatitis.[2][3]
It can also occur in the breast,[4] the salivary glands and neonates after a traumatic delivery.
