In scleroderma, calcific deposits are found predominantly in the extremities, around joints, and around bony prominences. Osteonecrosis has also been reported. [54]

Deposits typically are found in the flexor surfaces of the hands and the extensor surfaces of the forearms and knees.

The deposits rest in the dermis but can be found in deeper periarticular tissues.
