title: Primary peripheral primitive neuroectodermal tumour of the orbit.
abstract: METHODS
  We present the clinical, radiologic, and histopathologic features of an orbital mass in a 10-year-old boy. Immunohistochemistry confirmed the diagnosis of primary peripheral primitive neuroectodermal tumour.
  
  
  CONCLUSIONS
  This recently recognized rare tumour of the orbit should be considered in the differential diagnosis of hypercellular small round cell tumour of the orbit.
