Low grade pre-cancerous lesions (VIN) are typically [[HPV]] positive, while high grade pre-cancerous lesions and [[cancer]] are less often HPV positive.<ref name=pmid19115209>{{cite journal |author=De Vuyst H, Clifford GM, Nascimento MC, Madeleine MM, Franceschi S |title=Prevalence and type distribution of human papillomavirus in carcinoma and intraepithelial neoplasia of the vulva, vagina and anus: a meta-analysis |journal=Int.

Like SCC elsewhere. | |||
*Microinvasion: <=1 mm stromal invasion, tumour size <=2 cm (T1a).<ref>URL: [http://www.cap.org/apps/docs/committees/cancer/cancer_protocols/2011/Vulva_11protocol.pdf http://www.cap.org/apps/docs/committees/cancer/cancer_protocols/2011/Vulva_11protocol.pdf]. Accessed on: 9 March 2012.</ref> | |||
*Depth from DE junction. | |||
Note: | |||
*Tumour thickness != depth of invasion. | |||
**Thickness = granular layer ''or'' surface (no granular layer present) to deepest tumour. | |||
**Depth of invasion = epithelial-stromal junction in "valley" of papillae. | |||
