title: Respiratory choristomatous cysts in the temporal orbit.
abstract: OBJECTIVE
  To describe the clinical and histopathological findings in two patients with cystic lesions located in the temporal orbit.
  
  
  METHODS
  Case reports.
  
  
  RESULTS
  Cystic lesions excised from the temporal orbit of two patients were found to be lined with ciliated pseudostratified epithelium, consistent with a choristoma composed of tissue derived from the respiratory system. A review of the literature suggests that this is an uncommon cause of a cystic orbital mass.
  
  
  CONCLUSIONS
  Respiratory choristomatous cysts should be considered in the differential diagnosis of cystic lesions of the temporal orbit.
