Aetiologically unexplained deposition of calcium salts in pathologically altered cutis, subcutis or muscles, without detectable calcium or phosphate metabolic disturbance.
The term calcinosis dystrophica is generally equated with the terms calcinosis metabolica and calcinosis idiopathica. Dystrophic calcinosis occurs in scars, chronic inflammatory infiltrates, cysts, epitheliomas, carcinomas, hemangiomas in organized thrombophlebitis (phlebolite) and others.

Disseminated dystrophic calcinosis is mainly observed in the following systemic diseases:
