Central nervous system leiomyosarcoma in patients with acquired immunodeficiency syndrome

Abstract

✓ Leiomyosarcomas (LMSs) of the central nervous system are extremely rare; however, they are becoming more prevalent in immunocompromised patients. The authors present the cases of two patients with acquired immunodeficiency syndrome: one with LMS of the thoracic vertebral body and the other with LMS originating from the region of the cavernous sinus. The epidemiological and histological characteristics of LMS and its association with latent Epstein—Barr virus are discussed, as well as the treatments for this neoplasm.
