Provisional diagnosis: | Type 3 transformation zone; normal cervix with atrophic change. |
Management: | No further screening is required. |
Histopathology: | Not done. |
Comment: | Blood vessels can have confusing patterns. The vessels seen over the anterior lip of the cervix are difficult to distinguish from atypical vessels. However, the absence of any acetowhite area helps to clinch the diagnosis. |
