    Case Summary
    Provisional diagnosis: Type 1 transformation zone; low-grade squamous intraepithelial lesion (LSIL).
    Management: Punch biopsy from 12 o’clock position.
    Histopathology: Normal.
    Comment: Thin acetowhite patch with irregular margin can be seen in metaplasia or LSIL. Difficult to distinguish colposcopically.
