Abstract:
We report a rare case of dystrophic calcinosis in a patient with rheumatoid arthritis in bilateral buttock lesions and the right elbow joint. The calcinosis was surgically removed because it caused severe local pain, possible infection, and difficulty in sitting. Because no recommended standard pharmacotherapy exists for dystrophic calcinosis, surgical treatment should be taken into consideration when calcinosis causes severe local pain or restricts activities of daily life.
