title: Reactive lymphoid hyperplasia one month after LASIK surgery.
abstract: BACKGROUND
  To describe a case of reactive lymphoid hyperplasia following laser assisted in situ keratomileusis (LASIK).
  
  
  METHODS
  This observational case report describes a 31-year-old man who underwent LASIK and presented 1 month later with a fleshy, conjunctival (plical) tumour in the left eye. An excisional biopsy of the tumour was performed.
  
  
  RESULTS
  Histopathology of the excised tumour revealed reactive lymphoid hyperplasia involving the left conjunctiva.
  
  
  CONCLUSIONS
  Conjunctival lymphomas can masquerade as chronic conjunctivitis and can be preceded by reactive lymphoid hyperplasia. It is important to identify and differentiate these tumours. This report describes the unusual occurrence of a lymphoid conjunctival tumour after LASIK eye surgery.
