'''Calcinosis''' is the formation of calcium deposits in any soft tissue.<ref>{{cite book |last1=Le |first1=Cuong |last2=Bedocs |first2=Paul M. |title=Calcinosis Cutis |date=17 July 2021 |pmid=28846311 |url=https://www.ncbi.nlm.nih.gov/books/NBK448127/ |access-date=29 December 2021 |language=en}}</ref> It is a rare condition that has many different causes. These range from infection and injury to systemic diseases like kidney failure.

==Types== ===Dystrophic calcification=== The most common type of calcinosis is dystrophic calcification. This type of calcification can occur as a response to any soft tissue damage, including that involved in implantation of medical devices.

===Metastatic calcification=== Metastatic calcification involves a systemic calcium excess imbalance, which can be caused by hypercalcemia, kidney failure, milk-alkali syndrome, lack or excess of other minerals, or other causes.

===Tumoral calcinosis=== The cause of the rare condition of tumoral calcinosis is not entirely understood. It is generally characterized by large, globular calcifications near joints.
