Extranasopharyngeal angiofibroma (ENA) is an angiofibroma that occurs in the extranasopharynx. It shows pathologic findings, such as juvenile angiofibroma (JNA), which accounts for 0.5% of head and neck mass. However, compared with JNA, the prevalence, affected site, and clinical characteristics are completely different, which leads some physicians to classify ENA as a disease different from JNA. ENA of the nasal turbinate origin are rarely reported in the literature. In addition, choanal polyp originating from the posterior part of the nasal turbinate is uncommonly reported. Recently, we encountered two cases of ENA, which were not diagnosed by intraoperative frozen section examination, but were histopathologically diagnosed post-operatively. Although we were unable to diagnose and perform embolization pre-operatively, ENA has been successfully treated by endoscopic surgery, without profuse bleeding.
鼻外咽血管纤维瘤（ENA）是一种发生于鼻外咽的血管纤维瘤。它表现出如青少年血管纤维瘤（JNA）的病理特征，JNA占头颈部肿块的0.5%。然而，与JNA相比，其患病率、受累部位及临床特征完全不同，这使得一些医生将ENA归类为与JNA不同的疾病。文献中很少报道起源于鼻甲的ENA。此外，起源于鼻甲后部的后鼻孔息肉也鲜有报道。最近，我们遇到了两例ENA病例，术中冰冻切片检查未能诊断，但术后经组织病理学确诊。尽管我们术前无法诊断并进行栓塞治疗，但ENA已通过内镜手术成功治疗，且未出现大出血。
