Pathologic calcification
Pathologic calcification is divided into 2 types:
1. Metastatic calcification
This is caused by hypercalcemia, resulting from hyperparathyroidism, milk-alkali syndrome, sarcoidosis etc…
2. Dystrophic calcification
This occurs in previously damaged tissue, such as areas of old trauma, tuberculous lesions, scarred heart valves, & atherosclerotic lesions.
Unlike metastatic calcification, it is not caused by hypercalcemia. Typically, the serum calcium level is normal.
