    Case Summary:

    Provisional diagnosis: Type 1 transformation zone; normal.
      
    Management: Routine screening after 5 years.
      
    Histopathology: Not done.
    Comment: The columnar epithelium of ectropion has started to be covered by metaplastic epithelium. The outer boundary of the transformation zone can be delineated by the presence of the crypt openings and iodine-negative areas.
