Mucocutaneous lichen planus (LP) is a relatively common condition with varying clinical presentations. It can present in an individual with cutaneous LP or in isolation. Mucocutaneous LP may be erosive and ulcerative with significant scarring, pain, discomfort, and dysfunction, resembling lichen sclerosus, or present with thickened / hypertrophic lesions.
See oral lichen planus for oral mucosal presentation and lichen planopilaris for scalp presentation.
Certain medications may cause a lichenoid drug eruption, which is indistinguishable from typical LP.
