E22. ISSVD Terminology for Vulvar Intraepithelial Neoplasia (VIN) and Squamos Intraepithelial Lesions (SIL) (video)

In this episode of Talking O&G: a RANZCOG Podcast, host Dr Anna Clare speaks with Conj A/Prof Tania Day about gynaecologists' role in prevention of vulvar squamous cell carcinoma by identifying and treating vulvar intraepithelial neoplasia (VIN) and distinguishing these from benign squamous intraepithelial lesions (SIL). They unpack the recently published 2026 International Society for the Study of Vulvovaginal Disease (ISSVD) terminology guide, on which Conj A/Prof Day was lead author.   The ISSVD terminology was last updated in 2015, and there have since been major advancements in the clinical understanding of VIN histopathology and immunohistochemistry. Dr Clare and Conj A/Prof Day examine these developments, outlining the new preferred terminology, as well as diagnosis, treatment, and follow up. They highlight the importance of consistent language to aid collective efforts in vulval cancer elimination.   🔗 Resources mentioned in this episode:  2026 International Society for the Study of Vulvovaginal Disease (ISSVD) terminology for vulvar intraepithelial neoplasia and squamous intraepithelial lesions  📌 RANZCOG members can submit CPD at: https://shorturl.at/iq733   💬 If you found this episode valuable, please rate, review, subscribe, and share it with your colleagues.  RANZCOG acknowledges the need for more inclusive terminology for gender diversity.
