In contrast to an artifact of crowded cells, the calcification characteristically extends outside the focal plane, as the background DCIS is blurred in this focus. Dystrophic calcification ( DC ) is the calcification occurring in degenerated or necrotic tissue , as in hyalinized scars, degenerated foci in leiomyomas , and caseous nodules .
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]
Monckeberg's calcification typically occurs near the internal elastic lamina or, less frequently, in the media of muscular arteries without alterations in calcium metabolism. Its clinical importance is not yet fully understood. Some recent studies suggest a connection between Monckeberg's calcification and metabolic vascular calcification.
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 ...
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 .
In some, the x-ray findings may correspond to symptoms of back stiffness with flexion/extension or with mild back pain. [2] Back pain or stiffness may be worse in the morning. [ 4 ] Rarely, large anterior cervical spine osteophytes may affect the esophagus or the larynx and cause pain , difficulty swallowing [ 5 ] [ 6 ] or even dyspnea . [ 7 ]
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]
