Two Cases of Circumscribed Calcinosis

Two cases with circumscribed calcinosis of skin are described. One is an obvious case with scleroderma, whereas the second is apparently idiopathic. However, a striking clinical similarity is seen in both. This together with other noncontributory clinical and laboratory findings observed in the second case seem suggestive that idiopathic type of calcinosis may present a preceeding or presenting symptom of a subclinical underlying disease.
