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, heart, or lungs. It is commonly seen in conditions like atherosclerosis or after tissue injury. The deposits are typically visible on imaging studies and can lead to stiffness or dysfunction in the affected area. Dystrophic calcification is often a sign of underlying disease or tissue damage, and while it may not always cause symptoms, it can complicate existing health issues.
