The Prevalence of Lichen Sclerosus in Patients With Vulvar Squamous Cell Carcinoma.

Women with vulvar lichen sclerosus (LS) have an increased risk of developing differentiated vulvar intraepithelial neoplasia and vulvar squamous cell carcinoma (SCC). Our primary aim was to determine the prevalence of LS among women with vulvar SCC. All patients who underwent excision for invasive SCC of the vulva from January 1, 2009 to December 31, 2013 were identified by searching our institution's electronic laboratory information system (n=111).
