Diagrams of surgery for VIN
The diagrams on this page show the surgery that is done for vulval intraepithelial neoplasia (VIN).
This is sometimes called 'precancer'. Although there are cancer cells in the skin, they are trapped there and cannot move anywhere else. This is why this condition is not always regarded as a true cancer. The surgery for this condition removes the affected skin. So it is sometimes called a skinning vulvectomy. If part of your vulva is unaffected you may not need to have all of the skin removed.
A skinning vulvectomy
This first diagram shows the area of skin the surgeon will remove during the operation

The second diagram (below) shows the vulva after removal of the skin

This third diagram (below) shows the vulva with the remaining skin sewn back together after the skinning vulvectomy operation. The diagram shows the stitches. Once the area has healed, these should be smooth, neat lines of scar tissue. Above the vagina, you can see the opening of the bladder (the urethra) and the clitoris, both in place as before the operation.
