<prompt> Calcification of soft tissues without any disturbances of calcium metabolism is called:Inotrophic calcificationMonotrophic calcificationDystrophic calcificationCalcium induced calcification  <response>: Pathologic calcification is abnormal deposition of calcium, with small amount of iron, magnesium and other mineral salts in tissues. Dystrophic calcification is encountered in areas of necrosis, whether they are of coagulative, caseous, or liquefactive type, and in foci of enzymatic necrosis of fat. It is seen in deaddying cells with normal serum calcium levels and metabolism Metastatic calcification may occur in normal tissues in cases of hypercalcemia. There are four principal causes of hypercalcemia: Increased secretion of parathyroid hormone PTH resorption of bone tissues, secondary to primary tumors of bone marrow e.g., multiple myeloma, leukemia Vitamin D-related disorders Renal failure
