title: [Extramedullary plasmacytoma--manifestation in petrous bone].
abstract: BACKGROUND
  Extramedullary plasmocytoma of the temporal bone is a rare neoplastic disorder. Only a very few cases are described in the world literature.
  
  
  METHODS
  We report on a patient who presented with the clinical signs of a glomus jugular tumor. Postoperative histological evaluation revealed an extramedullary plasmocytoma of the temporal bone.
  
  
  CONCLUSIONS
  If a glomus tumor is suspected, histological investigation appears necessary if surgery is not possible or is contraindicated.
