Mucocutaneous lichen planus (LP) can present in an individual with cutaneous LP or in isolation. Vulvovaginal LP is a rare condition that usually presents in postmenopausal women. It is often accompanied by oral LP (the vulvovaginal-gingival syndrome), and cutaneous LP is present in up to one-quarter of patients. Vulval LP may be erosive and ulcerative, with accompanying pain, discomfort, dyspareunia, and secondary scarring, or it may present with thickened / hypertrophic lesions. If the vagina is affected, patients may report vaginal bleeding, vaginal discharge, and/or dyspareunia.
See oral LP for oral mucosal presentation, and see lichen planopilaris for scalp presentation.
Certain medications may cause a lichenoid drug eruption, which is indistinguishable from typical LP.
