Lichen planus is a chronic, inflammatory, mucocutaneous disease located mainly on the skin and covering mucous membranes, such as the genitals, the pharynx and the mouth.

It affects people of any age, but is usually observed in women over 50 years old.

The exact etiology of the disease is not fully comprehended. However, it seems that genetic and immune system factors are involved in its development with the prevailing view being that it is due to a cellular immune response.

Lichen planus can occur in the mouth exhibiting a variety of growth patterns. Among them, the erosive, ulcerative and to a lesser extent the atrophic form causes the patient symptoms of burning, stinging or pain following intense thermal, chemical or mechanical stimuli.

Frequently asked questions

How do I know if I have lichen planus?

The diagnosis is made by an Oral Medicine specialist after a detailed clinical examination and biopsy of the mouth from the affected area.

How can I avoid symptoms when brushing my teeth or after eating certain foods?

Use a soft toothbrush and avoid relatively ’irritating’ foods until the treatment you have been prescribed reduces the extent and severity of the disease.

Is there a definitive cure for lichen planus?

There is no definitive cure for the disease. The treatment of lichen planus is continuous and aims to keep the disease in remission by eliminating or at least reducing the patient’s symptoms.

How long should I be seen by a doctor regarding this disease?

As the disease is chronic with relapses and flares, there should be periodic monitoring at intervals determined by the course and severity of the disease. An additional reason for periodic follow-ups is the fact that in a small but considerable percentage of patients, the disease can develop into cancer, therefore the monitoring of changes and the possible performance of an additional biopsy are all necessary parts of a treatment plan.
