Extraskeletal (Ectopic) Calcification and Ossification
A significant number and variety of disorders cause extraskeletal deposition of calcium and phosphate (Table 1). In some, mineral is precipitated as amorphous calcium phosphate or as crystals of hydroxyapatite; in others, osseous tissue is formed. The pathogenesis of ectopic mineralization is generally attributed to one of three mechanisms (Table 1). First, a supranormal “calcium-phosphate solu...

Introduction: soft tissue calcification is a relatively common issue in panoramic radiography. These opacities include calcification of lymph nodes, tonsilolith, sialolith, calcification of stylohyoid complex and carotid artery bifurcation. This study aimed to determine the prevalence of soft tissue calcification in panoramic radiographs, their differential diagnosis, and their correlation with...
متن کاملElectromagnetic fields promote severe and unique vascular calcification in an animal model of ectopic calcification.
BACKGROUND The effects of electromagnetic fields (EMFs) on cardiovascular calcification is unknown. We sought to evaluate the effects of EMF on vascular calcification in normal rats and in rats with chronic kidney disease (CKD) - a condition which promotes calcification. METHODS We used four groups of rats: group 1 - exposed to EMF, group 2 - not exposed to EMF, group 3 - rats with CKD expose...
متن کاملAn unusual ectopic calcification in the left atrium.
A 60-year-old male presented with renal failure and right coronary myocardial infarction. Transesophageal echocardiography showed many tumors (Fig. 1). Endoscopy showed multiple ectopic calcifications in a line on the mitral annulus (Fig. 2). Ectopic calcifications were removed and mitral valve annu-plasty was performed. Histopathologic examination confirmed these were dense calcifications. Fig...
متن کاملAngiogenesis and pericytes in the initiation of ectopic calcification.
Ectopic calcification of blood vessels, heart valves, and skeletal muscle is a major clinical problem. There is now good evidence that angiogenesis is associated with ectopic calcification in these tissues and that it is necessary, but not sufficient, for calcification to occur. Angiogenesis may regulate ectopic calcification in several ways. First, many angiogenic factors are now known to exer...
