title: Cellular blue nevus of the conjunctiva.
abstract: BACKGROUND
  Cellular blue nevi of the conjunctiva are extremely rare, and their natural history and malignant potential have not been fully ascertained.
  
  
  METHODS
  A report of an unusually well-documented case of growth of a cellular blue nevus is presented, along with a review of current knowledge of this lesion.
  
  
  RESULTS
  A 71-year-old woman presented with a darkly pigmented raised lesion of the conjunctiva, which had slowly enlarged over 47 years. There were nonconfluent areas of involvement of the upper and lower lids. Results of biopsy showed the lesion to be a cellular blue nevus, with no evidence of malignancy.
  
  
  CONCLUSIONS
  This well-documented case of slow growth and spread without malignant transformation adds to the knowledge of this rare lesion.
