    Case Summary
    Provisional diagnosis: Type 1 transformation zone; high-grade squamous intraepithelial lesion (HSIL) in pregnancy.
     
    Management: Multiple punch biopsies obtained from the posterior lip and also from the extension of the lesion to the vaginal wall.
     
    Histopathology: HSIL-CIN3.
     
    Comment: The posterior lip had a large high-grade lesion that extended to the vagina. Biopsies were obtained to exclude invasive cancer. The anterior lip had a thin acetowhite area with indistinct margin that suggests metaplastic changes. The patient had LLETZ 2 months after normal delivery. The lesion was less extensive at that time. Sometimes apparently high-grade lesions in pregnancy may resolve completely after delivery. A repeat colposcopy 2–3 months after delivery is essential before making any decision about treatment.
