Provisional diagnosis: | Type 2 transformation zone; high-grade squamous intraepithelial lesion (HSIL). |
Management: | LLETZ (type 2 excision). |
Histopathology: | HSIL-CIN3. |
Comment: | Erosion is responsible for a false squamocolumnar junction (SCJ) in this case. The SCJ appears to be on the ectocervix in the posterior lip. In reality, it is situated just proximal to the external os in the canal. |
