text: <unk>  is a benign, vascular, polypoid fibrous mass in located in the the posterolateral wall of the nasal cavity. It was first described by Hippocrates, a Greek physician, in the 5th century BC.<unk>  may be classified according to Fisch classification into 4 groups.<unk>  is a histologically benign tumor. This tumor is located in the posterolateral wall of the nasal cavity. On gross pathology, characteristic findings of<unk>  include tan to purple-red, rubbery-firm unencapsulated polypoid fibrous mass. Fibroblastic cells with plump (near cuboidal) nuclei and abundant capillaries are seen on microscopic histopathological analysis. The cause of<unk>  has not been identified, but it may be caused by hormonal effect. Incidence of juvenile<unk>  is less than 0.5% of head and neck tumors. If left untreated, %9 of patients with<unk>  may progress to develop hemorrhage and intracranial extension. The hallmark of<unk>  is the classic triad of epistaxis, unilateral nasal obstruction and a mass in the nasopharynx. Physical examination of patients with<unk>  is usually remarkable for nasal mass and rhinorrhea. Findings on an x-ray suggestive of<unk>  include<unk>  polyp and Antral sign or Holman-Miller sign (Forward bowing of the posterior wall of the maxillary sinus). CT scan and MRI demonstrate the extent of the tumor. The mainstay of treatment for<unk>  is surgical resection.
