Dystrophic calcification (DC) is the calcification occurring in degenerated or necrotic tissue, as in hyalinized scars, degenerated foci in leiomyomas, and caseous nodules. This occurs as a reaction to tissue damage, [ 1 ] including as a consequence of medical device implantation.
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. [1]
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]
It is unclear whether Mönckeberg's arteriosclerosis is a distinct entity or forms part of a spectrum of vascular calcification that includes atherosclerosis and calcification in the inner layer of the artery wall (tunica intima), calcification of the internal elastic lamina, calcification of cardiac valves and widespread soft tissue ...
Dystrophic calcinosis cutis is the most prevalent kind of calcification on the skin. [2] The ectopic calcified mass usually consists of amorphous calcium phosphate and hydroxyapatite. [6] Dystrophic calcification is linked to a number of illnesses, such as infections, hereditary diseases, cutaneous neoplasms, and connective tissue diseases. [7]
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 .
When consisting of calcium phosphate, they are usually dystrophic calcifications (occurring in degenerated or necrotic tissue). [3] Yet, the mechanism of their formation is not fully known. [4] Calcium oxalate crystals in the breast may be seen on mammography and are usually benign, but can be associated with lobular carcinoma in situ. [5]
A peripheral ossifying fibroma, also known as ossifying fibrous epulis, is “a gingival nodule which is composed of a cellular fibroblastic connective tissue stroma which is associated with the formation of randomly dispersed foci of mineralised products, which consists of bone, cementum-like tissue, or a dystrophic calcification.
