title: Malignant peripheral nerve sheath tumour metastatic to the orbit.
abstract: OBJECTIVE
  To present a case of malignant peripheral nerve sheath tumour (MPNST) metastatic to the orbit.
  
  
  RESULTS
  The authors describe a 29-year-old woman with disseminated MPNST who presented with acute right orbital inflammation. Computerized tomography revealed a superolateral mass with a central radiolucent area. At biopsy, the mass was primarily subperiosteal and histology showed a spindle cell, S100-positive MPNST consistent with the primary tumour.
  
  
  CONCLUSIONS
  This is the second reported case of MPNST metastatic to the orbit and illustrates that an inflammatory presentation is possible in this aggressive malignancy.
