title: Childhood onset of pterygia in twins.
abstract: OBJECTIVE
  To report a case of childhood onset of pterygia in twins.
  
  
  METHODS
  Twelve-year-old male twins had nasal lesions on the left eye of twin A and on the right eye of twin B. Both lesions were excised with superior conjunctival autograft.
  
  
  RESULTS
  Histopathologic examination showed the lesions to be pterygia. Other pedigrees of familial pterygia have been described. However, to the authors' knowledge, this young age at onset has not been documented with histopathology in twins.
  
  
  CONCLUSIONS
  This case report documents the youngest age at onset of pterygia in twins, with histologic confirmation. It suggests a genetic or developmental cause for pterygium formation.
