    Case Summary
    Provisional diagnosis: Type 1 transformation zone; normal.
     
    Management: Routine screening after 5 years.
     
    Histopathology: Not done.
     
    Comment: The location of the crypt opening farthest away from the squamocolumnar junction helps to identify the extent of the transformation zone. Transformation zone can be very large, as in the present case.
