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.
