ORAL LICHEN PLANUS: SYMPTOMS & CAUSES, DIAGNOSIS & TREATMENT

Oral lichen planus (LIE-kun PLAY-nus) is an ongoing (chronic) inflammatory condition that affects mucous membranes inside your mouth. Oral lichen planus may appear as white, lacy patches; red, swollen tissues; or open sores. These lesions may lead to burning, pain or other discomfort.

Oral lichen planus can’t be transmitted from one person to another. The disorder happens when the immune system puts an attack against cells of the oral mucous membranes for unknown reasons (autoimmune disorder).

Symptoms can normally e managed, but people who have oral lichen planus need constant monitoring because they may be at risk of having mouth cancer in the affected places.
