title: An unusual case of epistaxis-juvenile nasopharyngeal angiofibroma.
abstract: BACKGROUND
  Epistaxis is a common complaint seen in the younger population. Its etiology is typically from the anterior nares, although we present a case of epistaxis from an uncommon source-juvenile nasopharyngeal angiofibroma. Juvenile nasopharyngeal angiofibroma (JNA) is a highly vascular, benign, yet locally invasive tumor that occurs in preadolescent males.
  
  
  OBJECTIVE
  To illustrate a case of epistaxis from an uncommon source.
  
  
  METHODS
  A 21-year-old man with a past medical history of allergic rhinitis presented to the Emergency Department (ED) after 6 months of intermittent yet worsening epistaxis. He described the bleeding as sudden onset that resolved after 30 min of direct compression of the external nares. He denied any history of digital manipulation, trauma, or bleeding disorders. Upon arrival in the ED, he had brisk bleeding from the right naris that was initially controlled with phenylephrine nasal spray. A small round friable mass was visualized in the right posterior nasal cavity. Further hemostasis of the epistaxis was achieved using a nasal tampon moistened with phenylephrine, and a computed tomography scan of the sinus revealed a soft tissue mass almost completely occupying the sphenoid sinus and extending into the nasopharynx and posterior ethmoids. There was also expansion and bony erosion of the right pterygopalatine fossa. A final diagnosis of JNA was made and the patient was given follow-up with an otorhinolaryngologist, who ultimately surgically resected the mass.
  
  
  CONCLUSIONS
  JNA is a highly vascular, benign, yet locally invasive tumor that occurs in preadolescent males. This case illustrates the importance of appreciating the more uncommon cases of epistaxis, especially when conventional methods of treatment have initially failed.
