Abstract

Vulvar lichen sclerosus (LS) is a chronic inflammatory dermatosis and is considered a precursor lesion of squamous cell carcinoma (SCC); with about 3% to 5% of cases progressing to SCC, even up to 7%. LS can be found in adjacent areas in more than 60% of cases of vulvar SCC. As a chronic scarring inflammatory dermatosis, vulvar LS can act as both an initiator and promoter of carcinogenesis. All suspicious lesions should be biopsied. Although the association between LS and SCC has been reported in the literature, actual case reports are rare in South Korea.
