title: [Pleomorphic adenoma of the nasal cavity: a case arising from the wall of the maxillary sinus].
abstract: BACKGROUND
  Pleomorphic adenoma is a common and benign tumour, originating from sero-mucous glands. Location in the nasal cavity and particularly on the medial wall of the maxillary sinus is very rare.
  
  
  METHODS
  One patient with a pleomorphic adenoma of the nasal cavity and a review of literature are reported in order to describe the diagnostic and therapeutic management of this tumour.
  
  
  RESULTS
  A 63-year-old woman was referred to our institution for evaluation of an unilateral nasal tumour. Clinical and radiological studies revealed an intra-nasal tumour, slightly lytic in nature, arising from the mucosa of the medial wall of the maxillary sinus. More than 2 years after complete excision of the tumour using an endoscopic procedure, the nasal cavity was free of tumour.
  
  
  CONCLUSIONS
  Pleomorphic adenoma of the nasal cavity is a rare and benign tumour, usually presenting as a unilateral nasal tumour. Prognosis of this tumour is mainly linked to recurrences in cases of incomplete resection and to possible metastasis, such as an eventual malignant evolution. The gold standard treatment is complete surgical resection. After a complete imaging study for patient selection (CT scan and MRI), endonasal endoscopic surgery seems to be a reliable therapeutic treatment.
  
  
  CONCLUSIONS
  Intra-nasal pleomorphic adenoma originates from nasal seromucous glands. Radiological study reveals a slightly lytic tumour developed from the septum of the medial wall of the maxillary sinus. Resecton can be performed with endoscopic endonasal surgery as long as the orbital bony framework and the ethmoidal roof are free of tumour. Whatever technique is employed, long term follow-up has to be used to detect any recurrence.
