[Epstein-Barr virus associated central nervous system leiomyosarcoma occurring after renal transplantation: case report and review of the literature]. / Léiomyosarcome primitif du système nerveux central associé au virus d'Epstein-Barr (EBV) et survenu après transplantation rénale : à propos d'un cas et revue de la littérature.

Central nervous system leiomyosarcomas are extremely rare, however, they became more frequent among immunodeficient patients, either in a patients infected with human immunodeficiency virus (HIV), or after organ transplantation. The data of the literature indicate that the infection by Epstein-Barr virus (EBV) plays a causal role in the development of these tumours but its precise role in the oncogenesis remains unresolved. We report a new case of EBV associated leiomyosarcoma of the left cavernous sinus occurring after renal transplantation. The epidemiological, clinical, pathological and therapeutic characteristics of these tumours are discussed.
