Abstract
1. The salient features of calcinosis universalis and calcinosis circumscripta are described.
2. The term "calcinosis localisata" is suggested to distinguish the localised type of calcinosis from the more widespread calcinosis.
3. Thirteen cases of calcinosis localisata are described: in five the lesion was situated about the greater tuberosity of the humerus; one was in the axillarv aspect of the shoulder; one on the dorsum of the foot; two in the digits of the hand; one on the dorsum of the wrist; one in the region of the flexor carpi ulnaris tendon; one on the lateral aspect of the elbow; and one at the tip of the greater trochanter.
4. The value of rest is emphasised; in some cases chemotherapy appeared to be indicated.
