title: Mucoepidermoid carcinoma of the eyelid skin.
abstract: OBJECTIVE
  Mucoepidermoid carcinoma involving the eye or its adnexa generally arises from the conjunctiva. We describe a nodular lesion of the lower eyelid skin with histologic features consistent with low-grade mucoepidermoid carcinoma.
  
  
  METHODS
  Case report.
  
  
  RESULTS
  By histology, the tumor demonstrated areas of squamous cell carcinoma and scattered islands of mucin-secreting cells. Histochemistry showed hyaluronidase-resistant mucin and intense immunoreactivity with an antibody against carcinoembryonic antigen suggesting that the tumor originated from acrosyringeal structures.
  
  
  CONCLUSIONS
  To our knowledge, this is the first report of a mucoepidermoid carcinoma arising from sweat glands in the eyelid skin.
