Signs and symptoms of oral lichen planus affect the mucous membranes of the mouth.
The lesions may appear as:
- Lacy, white, raised patches of tissues
- Red, swollen, tender patches of tissues
- Open sores
These lesions may appear on the:
- Inside of the cheeks, the most common location
- Inner tissues of the lips
Pain or discomfort
The red, inflamed lesions and open sores of oral lichen planus can cause a burning sensation or pain. The white, lacy patches may not cause discomfort when they appear on the inside of the cheeks but may be painful when they involve the tongue.
Other signs or symptoms
Other signs or symptoms may include:
- Change in taste or a blunted taste sensation if the tongue is affected
- Sensitivity to hot or spicy foods
- Bleeding and irritation with tooth brushing
- Inflammation of the gums (gingivitis)
Other types of lichen planus
If you have oral lichen planus, you may have lichen planus lesions affecting other parts of your body.
- Skin. Lesions usually appear as purplish, flat-topped bumps that are often itchy.
- Genitals. Lesions on the female genitalia often cause pain or burning and discomfort with intercourse. The lesions are usually red and eroded and occasionally appear as white areas. This can lead to scarring and loss of normal vaginal function and an inability to have intercourse.
- Ears. Lichen planus of the ears can lead to hearing loss.
- Scalp. When skin lesions appear on the scalp — a rare condition — they may cause temporary or permanent hair loss.
- Nails. Lichen planus of the toenails or fingernails, also rare, may result in ridges on the nails, thinning or splitting of nails, and temporary or permanent nail loss.
- Eyes. Rarely, lichen planus may involve the mucous membrane surfaces of the eyes, and can cause a loss of tear duct function and scarring of the eyelids.
- Esophagus. Lichen planus of the esophagus also is rare, but when it occurs, it may result in a narrowing of the esophagus or the formation of tightened, ring-like bands in the esophagus that can make swallowing difficult.
