High frequency of loss of heterozygosity in vulval intraepithelial neoplasia (VIN) is associated with invasive vulval squamous cell carcinoma (VSCC).
Vulval intraepithelial neoplasia (VIN) is thought to be the premalignant phase of human papillomavirus (HPV)-associated vulval squamous cell carcinoma (VSCC). Various molecular events have been suggested as markers for progression from VIN to VSCC, but loss of heterozygosity (LOH) in vulval neoplasia has rarely been studied in this context. We performed LOH analysis by polymerase chain reaction...
متن کاملAKT1 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 pre...
متن کاملVulval squamous cell carcinoma arising in chronic hidradenitis suppurativa.
Hidradenitis suppurativa is a chronic inflammatory disease of the sweat glands and hair follicles which is rarely associated with squamous cell carcinoma (SCC). A case of vulval SCC complicating hidradenitis suppurativa is presented. In addition to being the first case to report the association of vulval SCC and hidradenitis suppurativa in the English language literature, it also illustrates th...
متن کاملHuman papillomavirus infection and p53 protein expression in vulvar intraepithelial neoplasia and invasive squamous cell carcinoma.
The etiopathogenesis of vulvar intraepithelial neoplasia (VIN III) and invasive squamous cell carcinoma are largely unknown. Since there are few studies on Brazilian patients, our purpose was to determine the frequency of human papillomavirus (HPV) infection and the expression of p53 in these lesions, and associate them with other factors such as age, morphological subtypes, multicentric and mu...
متن کاملP53 expression in vulvar carcinoma, vulvar intraepithelial neoplasia, squamous cell hyperplasia and lichen sclerosus.
BACKGROUND p53 inactivation due to oncogenic viral proteins or mutations is an important molecular mechanism in carcinogenesis, which has also been demonstrated for vulvar carcinoma. To evaluate p53 changes in vulvar carcinogenesis, we analyzed p53 expression in vulvar carcinoma, vulvar intraepithelial neoplasia (VIN), lichen sclerosus (LS) and squamous cell hyperplasia (SH). PATIENTS AND MET...
