Ulcerated dystrophic calcinosis cutis secondary to localised linear scleroderma.

Dystrophic calcinosis is a more common form of calcinosis cutis; calcium salts are deposited secondary to local inflammation, tissue damage and degeneration. Various conditions can cause dystrophic calcinosis, including connective tissue disease, infection, inflammatory processes, chronic venous stasis, cutaneous neoplasm and trauma. We report a case of ulcerated cutaneous calcinosis associated with a localised linear scleroderma or morphea. Healing of the ulcerations took place after four months of treatment with colchicine 1 mg per day.
