title: [Atypical melanocytic nevus of the limbus. A case report].
abstract: METHODS
  A 78-year-old-woman presented with a corneal non-pigmented vascularised tumour of her left eye, of 2 months onset, but with no previous ocular disorders. Surgical excision was performed, and the histopathological study showed the lesion to be an atypical melanocytic nevus of the limbus.
  
  
  CONCLUSIONS
  Corneal pigmented lesions tend to occur as a result of conjunctival or sclerocorneal limbus lesions spreading or arising de novo from melanocytic cells that have migrated following corneal injury. A biopsy should be carried out to type and distinguish benign lesions (nevus) from pre-malignant or malignant lesions (primary acquired melanosis or conjunctival melanoma).
