title: Eyelash loss associated with hyperthyroidism.
abstract: OBJECTIVE
  To describe a patient with eyelash loss as the presenting feature of hyperthyroidism.
  
  
  METHODS
  Case report.
  
  
  RESULTS
  A 19-year-old woman presented with right upper eyelid eyelash loss. Thyroid function studies confirmed hyperthyroidism. She subsequently lost further eyelashes and a patch of scalp hair. Once the hyperthyroidism was treated, the eyelashes and scalp hair regrew.
  
  
  CONCLUSIONS
  Eyelash loss may be an early sign of the hyperthyroid state.
