흉추부에 발생한 간엽성 연골육종 : 증례보고 Case Report = Mesenchymal Chondrosarcoma of the Thoracic Spine

다국어 초록 (Multilingual Abstract)

Messnchymal chondrosarcoma is a rare tumor occurring in both bone and soft tissues and exhibits characteristics of a highly malignant tumor. The authors experienced a case of mesenchymal chondrosarcoma occurring in a 39-year-old man, which had invaded the soft tissues of the chest wall and had been incompletely removed, and recurred in the adjacent 710 vertebra 4 years later. The patient presented with severe back pain and paraparesis at admission. Radiographic studies of the vertebra showed an aggressive osteolysis of the vertebral body, pedicle, lamina, compression of the spinal cord, and soft tissue invasion. The tumor was totally removed by an anterior and posterior combined approach. The removed vertebral body was replaced with a titanium mesh cage, and the thoracic spine was stabilized by both anterior and posterior fixations with instruments. The pathological and the clinical characteristics of mesenchymal chondrosarcoma are discussed.
