* * *
A condition characterized by the deposition of calcium salts in nodular foci in various tissues other than the parenchymatous viscera; the two well-known forms, c. circumscripta and c. universalis, are not associated with tissue damage or demonstrable metabolic disease; other forms are the result of abnormal calcium and/or phosphorous metabolism. See metastatic calcification. [calcium + -osis, condition]
- c. circumscripta localized deposits of calcium salts in the skin and subcutaneous tissues, usually surrounded by a zone of granulomatous inflammation; clinically, the lesions resemble the tophi of gout.
- c. cutis a deposit of calcium in the skin; usually occurs secondary to a preexisting inflammatory, degenerative, or neoplastic dermatosis, and is frequently seen in scleroderma. See metastatic calcification. SYN: dystrophic c..
