Dystrophic calcification is a process where calcium deposits form in damaged or necrotic tissues, often occurring in areas of inflammation or injury. This type of calcification is not related to calcium metabolism and can happen in various tissues, such as muscle, lungs, or blood vessels. The deposits are typically a result of local tissue damage, leading to the accumulation of calcium salts. Dystrophic calcification can be seen in conditions like atherosclerosis or after tissue injury, and it may contribute to further complications in affected organs.
