What are the clinical symptoms of vulval lichen planus?

Patients most commonly present with complaints of vulvovaginal burning, pruritus, postcoital bleeding, and dyspareunia. Up to 70% of patients also have vaginal lesions. There may be an associated purulent vaginal discharge and chronic erosions of the vaginal epithelium can lead to the development of extensive adhesions leading to vaginal narrowing and obliteration.
