it arises from the superior margin of the sphenopalatine foramen and accounts for 0.05% of all head and neck neoplasms . the typical histopathologic appearance of jna is numerous wide , irregular vessels with a single layer of endothelial cells embedded in fibrous stroma . the abundant vascular component is responsible for the excessive bleeding during surgery or following biopsies.1 
  extranasopharyngeal angiofibromas ( enas ) have been reported sporadically in the literature . they most commonly originate from the maxillary sinus , and women are affected . compared with nasopharyngeal fibromas , the lesion is diagnosed earlier , is less vascularized , and occurs in older patients.2 similar to jnas , the treatment of choice for enas is surgery . the surgical approach is tailored to the location and size of tumor.1 in our case , the tumor was small enough for total excision with an endonasal endoscopic approach . this is the first case report in the english literature of angiofibroma originating in the inferior turbinate in a young woman . enas are rarely seen , and the inferior turbinate is an extremely rare location for them . there are reports in the english literature of inferior turbinate angiofibroma in male patients.3

 6 in female patients , there is only one case report in the english literature of inferior turbinate angiofibroma in a 52-year - old woman.7 recently , a report was published of a 9-year - old girl with angiofibroma obstructing the nasal cavity and originating from the inferior turbinate.8 
  differential diagnosis includes fibrosed antrochoanal and ethmoidal polyp and other fibrovascular tumors , such as capillary hemangioma , hemangiopericytoma , and solitary fibrous tumor.3 a 26-year - old woman was referred to our clinic with intermittent epistaxis from the right nasal passage for the previous 2 months . maxillofacial magnetic resonance imaging showed a lobular , contoured mass originating from the right inferior turbinate and hanging to the right of the nasal cavity , with dense contrast enhancement denoting hypervascularity ( figs . 1 , 2 , and 3 ) . we decided to embolize the vascular feeding of the mass to make surgery more feasible . the patient consulted with the invasive vascular radiology department and decided on the embolization process under intravenous sedation . vascular feeding of the mass was seen from the right internal maxillary artery , and this branch was embolized . when looking at the posterior wall of the sinus and pterygopalatine fossa , no masslike structure was evident . the approximately 3-cm - diameter mass originated from the posterior edge of the right inferior turbinate ( fig . a partial turbinectomy was performed , and the posterior edge of the remaining turbinate was cauterized . a mean age of 20 to 30 years in enas was found in the literature.1

 9 our case was also in this group . enas mostly originate from the maxillary sinus.2 there are also some reports of tumors located in the ethmoid sinus , nasal cavity , nasal septum , larynx , sphenoid sinus , cheek , conjunctiva , oropharynx , retromolar area , and middle turbinate.3

  the clinical presentation of enas depends on tumor localization . in our case , but because of the limited space in the nasal cavity , diagnosis was made at an early tumor stage . the tumor 's location indicated that the origin may be from ectopic tissues located further from its usual place.17 
  there is also a reported case of an angiofibroma arising from the inferior turbinate after co2 laser turbinoplasty.18 in our case , there was no history of turbinate surgery . selective angiography is a useful diagnostic method to demonstrate tumor vascular composition and to confirm the diagnosis . endoscopic and radiologic examination is important , but definitive diagnosis is made by histopathologic analysis . we should consider these neoplasms possibly in female patients , at every age , with extranasopharyngeal localization , and we should not perform biopsy because of massive bleeding .
introduction  juvenile nasopharyngeal angiofibroma is a rare benign neoplasm in the nasopharynx . 
 the tumor tends to be locally aggressive and is typically seen in adolescent boys . 
 extranasopharyngeal angiofibromas have been reported sporadically in the literature . 
 they most commonly originate from the maxillary sinus . 
 objectives  a 26-year - old woman was referred to our clinic with intermittent epistaxis from the right nasal passage for the previous 2 months . 
 maxillofacial magnetic resonance imaging showed a lobular , contoured mass originating from the right inferior turbinate and hanging in the right nasal cavity , with dense contrast enhancement denoting hypervascularity 
 . 
 resumed report  vascular feeding of the mass was seen from the right internal maxillary artery with angiography , and this branch was embolized . on the following day , the patient underwent transnasal endoscopic excision of the mass . 
 an approximately 3-cm - diameter mass was excised by partial turbinectomy , and the posterior edge of the remaining turbinate was cauterized . 
 conclusion  extranasopharyngeal angiofibromas are rarely seen , and the inferior turbinate is an extremely rare location for them . 
 this young woman is the first case reported in the english literature of angiofibroma originating from the inferior turbinate . 
 we should consider these neoplasms can be found in female , nonadolescent patients with extranasopharyngeal localization , and we should not perform biopsy because of its massive bleeding .
