title: Osteoblastoma of the nasal septum.
abstract: OBJECTIVE
  To present a case of, and to review the literature concerning, osteoblastoma of the nasal cavity, and to demonstrate the importance of considering this rare entity when assessing patients presenting with a nasal septum lesion.
  
  
  METHODS
  Benign osteoblastoma is a rare tumour, constituting 1 per cent of all bone tumours. Most cases occur in the long bones. Osteoblastoma involving the nasal cavity is rare, with only 10 reported cases in the English-language literature. Most nasal cavity cases originate from the ethmoid sinus and spread to involve the nasal cavity. There are only four reported cases of osteoblastoma originating from the bones of the nasal cavity. We report a case of osteoblastoma originating from the bony nasal septum in a 45-year-old man with a history of recurrent, right-sided epistaxis and nasal obstruction.
  
  
  CONCLUSIONS
  This is the second report in the English-language literature of osteoblastoma originating from the bony nasal septum.
