title: A case of episcleral neurofibroma.
abstract: OBJECTIVE
  To report a rare case of episcleral neurofibroma and discuss the possible differential diagnoses.
  
  
  METHODS
  Case report of a 36-year-old man who presented with a painless epibulbar mass of the left eye. We describe the clinical and histopathologic features of the tumour and compare it with other tumours which may have a similar clinical presentation.
  
  
  RESULTS
  An excisional biopsy of the tumour was performed. Histopathologic examination revealed the tumour to be an isolated episcleral neurofibroma.
  
  
  CONCLUSIONS
  It is often difficult to clinically differentiate this tumour from other conditions. Because of the slow growth of neurofibromas and its slow risk of malignant transformation, these lesions may be observed periodically for progression. Surgical excision may be performed if the lesion is found to be progressively enlarging in size.
