STUDY DESIGN: A primary leiomyosarcoma located on the left side of the C2 is reported. Left-sided partial spondylectomy and anterior reconstruction with posterior stabilization was performed by a two-staged operation. OBJECTIVE: To emphasize the occurrence of primary leiomyosarcoma and the importance of proper stabilization in the upper cervical spine. SUMMARY OF BACKGROUND DATA: Leiomyosarcoma is a rare malignant neoplasm of the bone and the primary leiomyosarcoma of the spine is extremely rare. Radical tumor excision is the goal in case of vertebral leiomyosarcoma, but to both gain surgical access to the upper cervical spine and obtain anterior reconstruction is challenging. METHODS: Leiomyosarcoma of the C2 in a 25-year-old woman with mild neurologic deficits is reported. A left-sided partial spondylectomy of C2 was performed. The defect of the vertebral body was reconstructed by expandable titanium prosthesis, and posterior craniocervical fixation was performed by the polyaxial screws in the lateral masses and rod/plates. RESULTS: The surgical margin was very small. The pathology of the tumor was reported as leiomyosarcoma. No sign of local recurrence or metastasis was evident 1 year after surgery. CONCLUSION: Leiomyosarcoma, although rare, should be kept in mind as one of the possible diagnoses when a patient with an upper cervical tumor is presented and complete tumor removal must be the goal.
