Final answer:
Treatment for lichen planus includes topical corticosteroids or calcineurin inhibitors for mild cases and oral corticosteroids or immunosuppressive medications for severe cases. In mild cases, no treatment may be necessary as the condition may resolve on its own.
Step-by-step explanation:
Treatment for lichen planus depends on the severity and location of the symptoms. In mild cases, no treatment may be necessary as the condition may resolve on its own. However, if symptoms are bothersome or affecting daily life, topical corticosteroids or calcineurin inhibitors may be used to reduce inflammation and itchiness. For severe cases, oral corticosteroids or other immunosuppressive medications may be prescribed.
