Lichen planus
Lichen planus is an uncommon disorder involving a recurrent, itchy, inflammatory rash or lesion in the mouth. The exact cause is unknown, but the disorder is likely to be related to an allergic or immune reaction. The disorder has been known to develop after exposure to potential allergens such as medications, dyes, and other chemical substances. Symptoms are increased with emotional stress, possibly because of changes in the immune system during stress.
The most noticeable symptom of lichen planus is mild to severe itching at the site of a lesion. Oral lesions are often gray-white in color and, if left untreated, can develop into blisters or ulcers. Lesions may be tender or painful, with mild cases having no discomfort. They are generally located on the sides of the tongue or the inside of the cheek, and occasionally on the gums. In addition to lesions, there may be a metallic taste in the mouth accompanied by little to no saliva.
The goal of treatment is to reduce symptoms and speed healing of skin lesions. Treatments include antihistamines to control the body's immune response, lidocaine mouthwashes to ease any painful lesions, or topical creams to reduce swelling. If symptoms are mild though, no treatment may be needed.
