Nil or diffuse | Sharp but irregular, jagged, satellites | Sharp and even, difference in level | |
Fine, regular | Absent | Coarse or atypical vessels | |
< 5 mm | 5-15 mm or 2 quadrants | >15 mm, 3-4 quadrants, or endocervically undefined | |
Brown | Faintly or patchy yellow | Distinctly yellow |
Provisional diagnosis: | Type 3 transformation zone; high-grade squamous intraepithelial lesion (HSIL) of the cervix extending to the vagina. |
Management: | LLETZ (type 3 excision) with laser ablation of the residual vaginal lesion. |
Histopathology: | HSIL-CIN3. |
Comment: | CIN3 lesions may extend to the vagina, especially in elderly women. In such cases, LLETZ is crucial to exclude invasive focus, especially inside the endocervical canal. Hysterectomy with removal of adequate vaginal cuff may be performed after excluding invasive cancer by LLETZ. |
