Summary

Unwanted, pathological calcifications can be categorized based on the initiating stimulus: trauma, tumor, disturbances of mineral metabolism, inflammation, or idiopathic (unknown) causes, and can be found in almost all tissues. For example, pulmonary calcifications are common asymptomatic findings, usually discovered on routine chest X-ray or at autopsy, and can occur in a wide variety of disorders, while vascular calcification (arteriosclerosis) is a common finding in elderly people, and causes heart disease and cerebral disorders. Several cellular components are involved in pathological calcifications, and there is some evidence suggesting pathological mineralizations and ossifications are regulated processes. In terms of structure and elemental analysis, there are no significant differences between pathological mineralization and bone formation. Calcifications may be present in biological tissue, as well as in synthetic graft material, for example in vascular prostheses.
