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]
Metastatic calcification can occur widely throughout the body but principally affects the interstitial tissues of the vasculature, kidneys, lungs, and gastric mucosa. For the latter three, acid secretions or rapid changes in pH levels contribute to the formation of salts. [4]
May have calcification; Non-progressive; After drugs, such as methysergide or bromocriptine: Diffuse; Possible interstitial pulmonary fibrosis; Cancer-related Primary cancer, mainly mesothelioma: Associated with asbestosis; Progressive thickening; Metastasis or invasion, mainly from lung cancer: Progressive; Nodular changes; Lung tumors
"Pulmonary hyalinizing granuloma" is a lesion characterized by keloid-like fibrosis in the lung and is not granulomatous. Similarly, radiologists often use the term granuloma when they see a calcified nodule on X-ray or CT scan of the chest. They make this assumption since granulomas usually contain calcium, although the cells that form a ...
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 .
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]
Exposure to certain substances, such as asbestos, can cause generalised fibrosis of the lungs, which may involve the pleura and lead to fibrothorax. [7] Less common causes of fibrothorax include collagen vascular diseases such as systemic lupus erythematosus , sarcoidosis , and rheumatoid arthritis ; kidney failure leading to uraemia ; and side ...
Rarely, large anterior cervical spine osteophytes may affect the esophagus or the larynx and cause pain, difficulty swallowing [5] [6] or even dyspnea. [7] Similar calcification and ossification may be seen at peripheral entheseal sites, including the shoulder, iliac crest , ischial tuberosity , trochanters of the hip, tibial tuberosities ...
