Lichen sclerosus (LS) is the most common chronic vulvar condition. It is characterized by vulvar hypopigmentation and scarring with loss of normal architecture. Onset is typically at 35-45 years of age, but it can be seen in prepubertal children. Genetic and autoimmune factors are thought to contribute to the pathogenesis of LS.
The main symptom is pruritus, and at times, this can be incapacitating, interfering with daily activity and sleep. Dyspareunia and urinary retention may occur. It can also be asymptomatic, just with scarring and hypopigmentation.
Squamous cell carcinoma (SCC) can occur within LS genital lesions. There is a higher risk of SCC in untreated cases.
