Fat necrosis

From WikiMD's Wellnesspedia

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[5] and neonates after a traumatic delivery.
