A 17-year-old male patient presented with lower back pain and weakness of lower limbs. On radiological investigation, a destructive bony lesion involving the third lumbar vertebra was seen associated with soft tissue extension and an extradural component. The lesion was surgically excised in view of the rapidly progressing symptoms. The histologic diagnosis was histiocytic sarcoma. Further investigations did not reveal any other lesion elsewhere. The case is being presented in view of the uncommon occurrence of a primary extranodal histiocytic sarcoma of the lumbar spine, which simulated a primary bone tumor.
一位 17 岁男性患者以腰痛和下肢无力就诊。影像学检查显示第三腰椎破坏性骨病变，伴有软组织延伸和硬膜外成分。鉴于症状迅速进展，进行了手术切除。组织学诊断为组织细胞肉瘤。进一步的检查没有发现其他部位的病变。本病例是由于腰椎原发性结外组织细胞肉瘤罕见，模拟原发性骨肿瘤而提出的。
