Leukoplakia are patches on the tongue, in the mouth, or on the inside of the cheek that occur in response to long-term irritation. Leukoplakia patches may also develop on the outer female genitals.
Hairy leukoplakia; Smoker's keratosis; Vulvar leukoplakia
Leukoplakia mainly affects the mucus membranes of the mouth. It is thought to be caused by irritation, but the cause is not always known.
Irritation in the mouth may be caused by:
- Rough teeth
- Rough places on dentures, fillings, and crowns
- Smoking or other tobacco use (smoker's keratosis), especially pipes
- Holding chewing tobacco or snuff in your mouth for a long period of time
The disorder is most common in elderly persons.
"Hairy" leukoplakia of the mouth is a different disorder that is seen mostly in HIV-positive people. It may be one of the first signs of HIV infection. It can also appear in other people whose immune system is not working well, such as after a bone marrow transplant. It is caused by the Epstein-Barr virus, but is not harmful by itself. The most common symptoms of hairy leukoplakia are painless, fuzzy white patches on the side of the tongue.
Sores usually develop on the tongue, but they may also appear on the insides of the cheek, or on the outer female genitals. The most common symptoms of hairy leukoplakia are painless, fuzzy white patches on the side of the tongue.
The sores are:
- Usually white or gray
- Sometimes red (called erythroplakia, a condition that can lead to cancer)
- Thick and slightly raised with a hard surface that can't be easily scraped off
Exams and Tests
The typical white patch of leukoplakia develops slowly, over weeks to months. The lesion may eventually become rough in texture, and may become sensitive to touch, heat, spicy foods, or other irritation.
The goal of treatment is to get rid of the lesion. Removing the source of irritation is important and may cause the lesion to disappear.
- Treat dental causes such as rough teeth, irregular denture surface, or fillings as soon as possible.
- Stop smoking or using other tobacco products.
- Do not drink alcohol.
You may need surgery to remove the lesion. The lesion is usually removed in your health care provider's office using local anesthesia.
Leukoplakia on the vulva is treated in the same way as oral lesions.
Leukoplakia is usually harmless. Lesions often clear up in a few weeks or months after the source of irritation is removed.
Rarely, it may become cancer.
When to Contact a Medical Professional
Call for an appointment with your health care provider if you have any lesions resembling leukoplakia or hairy leukoplakia.
Stop smoking or using other tobacco products. Do not drink alcohol, or limit your number of alcoholic drinks. Have rough teeth treated and dental appliances repaired promptly.
