International Society for the Study of Vulvovaginal Disease Recommendations Regarding Female Cosmetic Genital Surgery.

Female genital cosmetic surgeries (FGCSs) and procedures are increasingly being advertised as common, simple, and complication-free, capable of not only improving aesthetic appearance but also increasing self-esteem and sexual pleasure.Guidelines for physicians and clear, scientifically correct information for patients must be made available, to minimize the number of ineffective or deleterious procedures.The International Society for the Study of Vulvovaginal Disease positions/recommendations regarding FGCS are as follows:1. There is a wide variation regarding genital normalcy; providers must be able to explain this to women.2. There are no data supporting FGCS including, G-spot augmentation, hymenoplasty, vulvar and perianal bleaching/whitening, vaginal tightening procedures, and other procedures aimed at increasing sexual function.3. Women should not be offered FGCS before the age of 18 years.4. Women undergoing FGCS should be evaluated by a provider with expertise in vulvovaginal diseases, including attention to their psychological, social, and sexual context. Evaluation by an experienced mental health provider should be considered when the motivation for seeking surgery and/or expectations are not clear or realistic.5. Female genital cosmetic surgery is not exempt from complications.6. Informed consent must always be obtained.7. Surgeons performing FGCS should refrain from solicitous advertising or promoting procedures without scientific basis, including on Web sites.8. Surgeons should not perform surgery that they do not agree with and explain their rationale/position when pressured by patients.9. The genital surgeon must be adequately trained in performing FGCS including knowledge of the anatomy, physiology and pathophysiology of the vulva, vagina and adjacent organs.

Is differentiated vulval intraepithelial neoplasia the precursor lesion of human papillomavirus-negative vulval squamous cell carcinoma?

Vulval squamous cell carcinoma appears to arise via 2 distinct pathways. A significant minority are associated with oncogenic human papillomavirus (HPV) infection and undifferentiated vulval intraepithelial neoplasia (VIN). However, the majority arises in the absence of HPV, on a background of chronic inflammation. Until recently, it was assumed that lichen sclerosus was the underlying inflammatory condition in the majority of HPV-negative cancers. This pathway of carcinogenesis has been less well studied than the HPV pathway. Emerging evidence implicates differentiated VIN (DVIN), rather than lichen sclerosus, as the most likely precursor lesion in HPV-negative vulval squamous cell carcinoma. Here we discuss the clinical and molecular evidence that implicates DVIN as a lesion with a high malignant potential. This lesion is probably underdiagnosed and may be undertreated. Better recognition of DVIN by gynecologists and pathologists may therefore offer an opportunity to prevent some vulval cancers.

Cutaneous mucinous carcinoma arising in extramammary Paget disease of the perineum.

We present the case of a 74-year-old woman with a 7-year history of an expanding vulval and perianal erythematous plaque, which failed to respond to topical treatments in the community. Biopsy of the affected skin showed typical features of extramammary Paget disease. No underlying associated malignancy was identified. After 2 months of treatment with 5% topical imiquimod, the patient developed a new tender nodule in the perineal region. Histological examination revealed a mucinous carcinoma, which, after careful clinical assessment, was deemed to be a primary cutaneous mucinous carcinoma. This is the second reported case of a primary cutaneous mucinous carcinoma arising on a background of extramammary Paget disease of the vulva and perineum.

AKT1 loss correlates with episomal HPV16 in vulval intraepithelial neoplasia.

Anogenital malignancy has a significant association with high-risk mucosal alpha-human papillomaviruses (alpha-PV), particularly HPV 16 and 18 whereas extragenital SCC has been linked to the presence of cutaneous beta and gamma-HPV types. Vulval skin may be colonised by both mucosal and cutaneous (beta-, mu-, nu- and gamma-) PV types, but there are few systematic studies investigating their presence and their relative contributions to vulval malignancy. Dysregulation of AKT, a serine/threonine kinase, plays a significant role in several cancers. Mucosal HPV types can increase AKT phosphorylation and activity whereas cutaneous HPV types down-regulate AKT1 expression, probably to weaken the cornified envelope to promote viral release. We assessed the presence of mucosal and cutaneous HPV in vulval malignancy and its relationship to AKT1 expression in order to establish the corresponding HPV and AKT1 profile of normal vulval skin, vulval intraepithelial neoplasia (VIN) and vulval squamous cell carcinoma (vSCC). We show that HPV16 is the principle HPV type present in VIN, there were few detectable beta types present and AKT1 loss was not associated with the presence of these cutaneous HPV. We show that HPV16 early gene expression reduced AKT1 expression in transgenic mouse epidermis. AKT1 loss in our VIN cohort correlated with presence of high copy number, episomal HPV16. Maintained AKT1 expression correlated with low copy number, an increased frequency of integration and increased HPV16E7 expression, a finding we replicated in another untyped cohort of vSCC. Since expression of E7 reflects tumour progression, these findings suggest that AKT1 loss associated with episomal HPV16 may have positive prognostic implications in vulval malignancy.
