    Case Summary
    Provisional diagnosis: Type 2 transformation zone; high-grade squamous intraepithelial lesion (HSIL).
    Management: LLETZ (type 2 excision).
    Histopathology: HSIL-CIN3.
    Comment: Erosion may give the appearance of a false squamocolumnar junction (SCJ) unless looked at carefully. In the present case, an inexperienced colposcopist may detect the SCJ on the ectocervix and miss the true SCJ within the canal.
