title: [Pleomorphic adenoma of the nasal septum].
abstract: BACKGROUND
  The pleomorphic adenoma is the most common benign neoplasm of primary salivary glands. However, its intranasal localization is exceptional. We report a case of pleomorphic adenoma of the nasal septum.
  
  
  METHODS
  A 64-year-old man presented with a left rhinological syndrome with nasal obstruction. A facial CT-scan showed a heterogeneous tumor of the nasal septum obstructing the left nasal vestibule. The biopsy analysis proved the histological characteristics of a pleomorphic adenoma, and was further confirmed by immunohistochemical study. The lesion was completely removed by endonasal surgery. There was no recurrence 18 months after surgery.
  
  
  CONCLUSIONS
  The treatment of nasal pleomorphic adenomas must take into account lesion localization, esthetic complications, and evolutionary potential of the lesions. Long-term follow-up is recommended because of the risk of recurrence or malignant degeneration.
