title: Mucoepidermoid carcinoma of an accessory lacrimal gland with orbital invasion.
abstract: OBJECTIVE
  To report a case of mucoepidermoid carcinoma of an accessory lacrimal gland with orbital invasion.
  
  
  METHODS
  The clinical history and pathologic findings of a patient with a left upper eyelid lesion were reviewed.
  
  
  RESULTS
  The patient was evaluated and found to have an epithelial tumor arising in an accessory lacrimal gland. Special stains showed mucin production by individual tumor cells. The tumor was classified as mucoepidermoid carcinoma.
  
  
  CONCLUSIONS
  Mucoepidermoid carcinoma may arise in accessory lacrimal glands and invade the orbit.
