| Provisional diagnosis: | Type 1 transformation zone; subclinical papillomavirus infection (SPI). | 
| Management: | Considering the extensive lesion, multiple biopsies should be taken to rule out CIN. No treatment is required for SPI. The woman should be screened after 5 years. | 
| Histopathology: | LSIL-HPV changes. | 
| Comment: | Case of extensive SPI. The presence of the lesion away from the transformation zone, fresh white colour, shiny pilled surface, raised border, and satellite lesions help in diagnosis. |
