Metastatic calcification is a condition where calcium deposits form in healthy tissues due to elevated levels of calcium in the blood, known as hypercalcemia. This can occur in various conditions, such as hyperparathyroidism, chronic kidney disease, or certain types of cancer. The excess calcium can lead to tissue damage and dysfunction. The deposits typically affect organs like the lungs, kidneys, and blood vessels. Unlike dystrophic calcification, which occurs in damaged tissues, metastatic calcification happens in normal tissues. Treatment focuses on addressing the underlying cause of hypercalcemia to prevent further complications.
