UNASSIGNED: Sinonasal @entity2698 ( @entity2698 ) is a soft tissue @entity5 of vascular origin. Open surgical methods and endoscopic techniques are considered the standard treatments for sinonasal @entity2698 . However, local recurrences resulting from @entity41 are common. Adjuvant radiotherapy and chemotherapy have also been used to treat @entity2698 , however, the number of studies which have investigated effective adjuvant treatments in the literature are limited. The current study reports a 42-year-old male with recurrent and intracranial invasion of sinonasal @entity2698 , diagnosed in Xuanwu Hospital (Beijing, China). The @entity1 underwent multiple surgeries to remove the @entity5 , however, no adjuvant therapy was adopted during this period and the @entity5 reoccurred within 1 year. On admittance to Tangshan @entity1 's Hospital (Tangshan, China), the @entity1 presented with @entity2133 opening and chewing ability, and @entity393 . Under observation using an electron microscope, @entity2698 usually consists of spindle-shaped cells with elongated nuclei and displays characteristic staghorn-like vascular channels. In the present case, immunohistochemical studies were performed on @entity982 -embedded sections of the @entity5 . The @entity5 cells expressed @entity2280 , @entity469 (+/-), epithelial membrane antigen, @entity2279 , a-actin, @entity2283 , @entity3778 , S-100, @entity1892 and Ki-67 (30%), but were negative for @entity908 kinase. The @entity1 was treated with intensity-modulated radiotherapy and adjuvant chemotherapy, which demonstrated efficacy. No recurrence and @entity3 was observed at the 1 year follow-up subsequent to the combined therapy.
