The association of Epstein-Barr virus （EBV） with smooth muscle tumors in immunocompromised patients is well established. The geographic distributions of EBV infection and nasopharyngeal carcinoma in China and the close proximity of the sinonasal area to the nasopharynx raise the possibility, that EBV may be involved in the pathogenesis of nasal smooth muscle tumors. Herein. we report a case of vascular leiomyonla of the nasal cavity in an 88-year-old man and discuss the rote of sex hormones in tumorigenesis and a possible relationship with EBV infection.展开更多
