| Nil or transparent | Thin, milky | Distinct, stearin | |
| 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 1 transformation zone; high-grade squamous intraepithelial lesion (HSIL). |
| Management: | Multiple punch biopsies from the anterior and posterior lips followed by LLETZ (type 1 excision). |
| Histopathology: | HSIL-CIN2. |
| Comment: | The high-grade lesion is seen on the background of extensive metaplastic changes. The transformation zone was very large. Prior histological confirmation is preferable before excising such a large transformation zone. |
