Mucosal lichen planus (MLP) is a chronic inflammatory disease of the mucosa. This condition can affect the mouth, esophagus, pharynx, genitalia, anus, and conjunctiva. This disease shows a tendency to chronicity with phases of relapses for a duration of 3-10 years. It presents with varying morphologies including lacy or fern-like, slightly raised striae, erosions, erythema, and atrophy. The pathophysiology is not yet fully understood and is dominated by the classic band-like lymphocytic infiltrate along the dermoepidermal junction. MLP is very challenging to treat, since the clinical course entails frequent relapses and shows resistance to therapy. The most commonly used local treatments are topical corticosteroids or calcineurin inhibitors. In addition to systemic glucocorticosteroids and traditional systemic drugs such as oral retinoids or methotrexate, emerging anti-inflammatory therapies such as Janus kinase inhibitors and biologics may be promising and are currently being evaluated in clinical trials. © 2022.
