title: [Solitary fibrous tumor of the cheek].
abstract: BACKGROUND
  A case of solitary fibrous tumour of the cheek is described.
  
  
  METHODS
  The lesion is documented by immunohistochemistry.
  
  
  RESULTS
  The patient is a 55 year old man and the tumor is constituted by a nodule measuring 2 cm in its greatest axis. The neoplastic cells are spindle shaped and arranged in a storiform pattern. They stain for vimentin and CD34.
  
  
  CONCLUSIONS
  The differential diagnosis from morphologically similar lesions, such as leiomyoma, schwannoma, benign fibrohistiocytoma and myoepithelioma of the salivary glands was taken in consideration. The present case, together with those reported in the literature, indicates that solitary fibrous tumours arise in any site of the organism.
