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.
假性肿瘤性钙化，尤其是脊柱周围，是系统性硬化症（SSc）的罕见并发症。作者报告了一例 60 岁女性局限性皮肤 SSc 的病例，其病史为 4 个月的背痛。体格检查发现左侧椎旁有一个约 7cm 长的肿块。计算机断层扫描（CT）显示左侧椎旁肌肉中有钙化肿块，从第 12 胸椎延伸到第 3 腰椎。诊断为 SSc 继发假性肿瘤性钙化。使用镇痛药进行对症治疗显著改善了临床症状。皮下钙化是 SSc 的常见并发症，但是假性肿瘤形式仍然极为罕见，特别是在胸腰椎周围。治疗仅限于镇痛治疗，或在更严重的情况下，手术切除。应进行随访以排除并发症。
