Calcinosis is the formation of calcium deposits in any soft tissue. 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.

gollark: It's probably true that there's *a* maximum size limit, but it isn't obviously 150.

gollark: Wikipedia says:> A replication of Dunbar's analysis with a larger data set and updated comparative statistical methods has challenged Dunbar's number by revealing that the 95% confidence interval around the estimate of maximum human group size is much too large (4–520 and 2–336, respectively) to specify any cognitive limit.

gollark: Dunbar's number is 150, and also a very approximate approximation someone made up.

gollark: Greetings.
