Abstract
Objective The authors studied 6 cases of osseous leiomyosarcoma of the spine. Two of these cases were of immunocompromised human immunodeficiency virus (HIV)-positive patients with Epstein-Barr virus (EBV)-associated primary vertebral leiomyosarcomas. The remaining 4 cases were of patients with leiomyosarcoma metastases to the spine. Methods Each patient underwent surgical resection of their vertebral mass; however, the patients with the EBV-associated tumors had the best postoperative prognosis. Results The HIV-positive patients have had no further local recurrence, while the other 4 patients had rapid local recurrences requiring multiple surgical interventions. Furthermore, the patients living with HIV have lived longer with fewer leiomyosarcoma-related health complications. Conclusions These findings suggest that EBV-associated vertebral leiomyosarcoma is of a less aggressive variety than metastatic leiomyosarcoma of the spine.
