Calcinosis is the formation of calcium deposits in any soft tissue. [1] It is a rare condition that has many different causes. These range from infection and injury to systemic diseases like kidney failure.
Metastatic calcinosis cutis is the consequence of calcium salts precipitating in normal tissue due to an underlying abnormality in the metabolism of phosphate and/or calcium. [2] Metastatic calcification can result from any systemic condition raising serum calcium and/or phosphate levels. Chronic renal failure is the most frequent underlying ...
Calcification is the accumulation of calcium salts in a body tissue. It normally occurs in the formation of bone, but calcium can be deposited abnormally in soft tissue, [1] [2] causing it to harden. Calcifications may be classified on whether there is mineral balance or not, and the location of the calcification. [3]
Ectopic calcification is a pathologic deposition of calcium salts in tissues or bone growth in soft tissues.This can be a symptom of hyperphosphatemia.Formation of osseous tissue in soft tissues such as the lungs, eyes, arteries, or other organs is known as ectopic calcification, dystrophic calcification, or ectopic ossification.
Idiopathic scrotal calcinosis is a cutaneous condition characterized by calcification of the skin resulting from the deposition of calcium and phosphorus occurring on the scrotum. [ 2 ] : 528 However, the levels of calcium and phosphate in the blood are normal. [ 3 ]
In dystrophic calcification, basophilic calcium salt deposits aggregate, first in the mitochondria, then progressively throughout the cell. [citation needed] These calcifications are an indication of previous microscopic cell injury, occurring in areas of cell necrosis when activated phosphatases bind calcium ions to phospholipids in the membrane.
Most people have no symptoms while others develop calcium deposits in the soft tissue. [1] The disorder is often accompanied by low calcium blood levels, which can result in muscle spasms. [1] Causes include kidney failure, pseudohypoparathyroidism, hypoparathyroidism, diabetic ketoacidosis, tumor lysis syndrome, and rhabdomyolysis. [1]
Kidney showing circumscribed calcium deposits together with a partial stag horn calculus. Nephrocalcinosis, once known as Albright's calcinosis after Fuller Albright, is a term originally used to describe the deposition of poorly soluble calcium salts in the renal parenchyma due to hyperparathyroidism.
