Metabolic cutaneous calcinosis is a comparatively rare condition in which an abnormal deposition of calcium salts is found in the skin, subcutaneous tissue and superficial fascia. Few cases have been reported until recently, although the condition was first described fifty years ago. Its cause is assumed to be a disturbance of calcium metabolism, the exact mechanism of which is not understood. The deposits, as reported, vary from 1 mm. to 4 cm. in diameter and usually assume the form of plaques or nodules. In a small percentage of cases there is an associated scleroderma.
