Calcinosis cutis

Calcinosis cutis (or cutaneous calcification) is a type of calcinosis wherein calcium deposits form in the skin. A variety of factors can result in this condition. The most common source is dystrophic calcification, which occurs in soft tissue as a response to injury. In dogs, calcinosis cutis is virtually pathognomonic for Canine Cushing's syndrome.
