Calcinosis cutis is a group of disorders characterized by the deposition of crystals of calcium phosphate (hydroxyapatite) in the skin in various areas of the body (Ianello et al. 1998) and can be associated with both normal and elevated calcium levels. Classically, it is divided into dystrophic, metastatic, iatrogenic, and idiopathic types.
