Pseudotumoral calcinosis of the spine in systemic sclerosis - an atypical location


Rato M, Rocha T, Bernardo A, Costa L


Pseudotumoral calcinosis, particularly around the spine, is a rare complication of systemic sclerosis (SSc). The authors report a case of a 60-year-old woman with a limited cutaneous SSc observed for a 4-month history of back pain. Physical examination revealed a left paravertebral mass measuring around 7cm in the longest axis. The computed tomography (CT) showed the presence of calcified mass in the left paravertebral muscle, extending from the 12th dorsal to the 3rd lumbar vertebra. A diagnosis of pseudotumoral calcinosis secondary to SSc was made. Symptomatic treatment with analgesics allowed a significant improvement of clinical symptoms. Subcutaneous calcinosis is a common complication of SSc, however the pseudotumoral form remains extremely rare, particularly around the dorsolumbar spine. Treatment is limited to analgesic therapy or, in more severe cases, to surgical excision. Follow-up should be conducted to rule out complications.
