title: Treatment of cystic epithelial downgrowth with intralesional administration of mitomycin C.
abstract: OBJECTIVE
  To report a case of postoperative cystic epithelial downgrowth treated with needle aspiration and intralesional administration of mitomycin C.
  
  
  METHODS
  Case report. A 60-year-old woman with a history of right cataract surgery 7 years ago presented with decreased vision of 1/60. The reduced vision was diagnosed secondary to a large acquired cystic epithelial downgrowth on the surface of the iris occluding the pupil.
  
  
  RESULTS
  The cystic epithelial downgrowth was treated with aspiration and intralesional administration of mitomycin C solution. There was no evidence of recurrence on follow-up 1 year after the procedure.
  
  
  CONCLUSIONS
  Treatment of acquired cystic epithelial downgrowth with needle aspiration and intralesional administration of mitomycin C resulted in a satisfactory outcome without undertaking more extensive and invasive surgical treatments.
