title: Enchondroma of the orbit.
abstract: OBJECTIVE
  To report a documented case of orbital enchondroma.
  
  
  METHODS
  A 25-year-old woman had an asymptomatic orbital mass. Computed tomographic scan was performed. The mass was surgically removed from the medial wall of the orbit, and the specimen was submitted for histopathologic examination.
  
  
  RESULTS
  The tumor showed typical radiologic and histopathologic appearance of an enchondroma with typical hypocellular lobules of cartilage enclosed by lamellar bone.
  
  
  CONCLUSIONS
  Cartilaginous neoplasms in the orbit are extremely rare.
