Definition of Dystrophic calcification

Reviewed on 6/3/2021

Dystrophic calcification: deposition of calcium (as calcium phosphate crystals) in body tissues in areas that have been injured or damaged. Calcium deposits may form when there is necrosis (tissue death) due to injury or other damage, such as infiltration by a tumor. Calcium may also be present in surgical sites or areas where devices have been implanted in the body. Examples of areas in the body where dystrophic calcification occurs include atherosclerotic plaques, damaged heart valves, and lymph nodes in the presence of tuberculosis infection.
