Metastatic calcification is a pathological process in which calcium is deposited in tissues where it should not be. It can occur in various organs including the lungs, kidneys, and heart. This condition is often a result of other diseases such as hyperparathyroidism or kidney failure. Synonyms for metastatic calcification include ectopic calcification, heterotopic calcification, and pathological calcification. These terms are used to describe the deposition of calcium in abnormal locations or tissues. The process of metastatic calcification can lead to organ dysfunction and may require medical intervention to treat underlying conditions and prevent further complications.
