Leukoplakia

Description leukoplakia

Leukoplakia is a disease in which white deposits appear on the surface of the body, most commonly on the mucous membranes. It also has several other characteristics.

Each surface of both the body and the inside of it is covered by one or more layers of cells, calledepithelial cells. Have a protective function, sometimes are wedged between them, secretory cells that produce mucus necessary. It also helps to protect the epithelium. An example might be the mucus produced by the salivary glands. One of its functions is to wrap food and stir with her and thereby ensure smooth passage through the digestive tube mouthful. If the mucus was lacking, food would epithelium scrubbed and thereby harming him. According to the shape distinguish squamousepithelium in which cells are most flattened epithelium cubic cells krychlického shaped andcylindrical epithelium where cells are high. If the cells are located in multiple layers, you may occur keratinization. It is the process which have a cell located in the lowest layer the greatest height (are therefore to cylindrical) and towards the surface cell layers are more flat. Most on the surface are then simply scales of dead cells that are completely flattened. Keratinization is typical for skin and epithelium is characteristic for locations which are exposed to mechanical action. It occurs mainly in the largest extent on the heels of your feet. Most of the mucosa is covered by squamous epithelium which nerohovatí. However, if the present leukoplakia occurs keratinization squamous epithelium in unusual places.

Leukoplakia is a disorder belonging to the metaplasia. They are characterized pathologically altered tissue converting back to tissue physiological state. Usually, however, transformed into tissue of another type.

As leukoplakia are most often called white areas on the mucous membranes. They can occur in the oral cavity, the mucosa of the bladder mucosa external female genital tract, but also elsewhere.So that could arise, must be in place thickened skin (acanthosis), which excessively rohovatí (keratosis). Some leukoplakia can cause malignant changes when tata flanked transformed into a cancer – squamous cell carcinoma.

A special type is hairy leukoplakia. Afflicting patients suffering from HIV infection or Epstein – Barr virus (EBV). In this leukoplaikie is altered mucosa edges language. As with other leukoplakia it is also possible to see well defined whitish precincts to the mucosa, which however occurs only in the front two-thirds of the tongue. At the same time but these districts may occur across the mouth – the mucosa cheek, palate, the lower jaw.

Oral mucosa is at most about leukoplakia affected even in the absence of HIV or EBV. This disease is called as oral leukoplakia, and because many of them are caused by smoking, we are divided according to the Origin into smoking and non-smoking leukoplakia leukoplakia. Most affected are men – smokers. For them, the disease manifests in middle age and older. Women smokers are six times less representation ill, but symptoms they show a little earlier than men.

The most frequent malignant transformation occurs with oral leukoplakia, paradoxically, belonging to the group of non-smoking even though smokers have a much higher risk of cancer.

Leukoplakia are several causes of, on the other is still only speculation. As already mentioned in oral leukoplakia, plays an important role smoking. Other factors may be alcohol (especially spirits), chronic irritation of the mucous membranes (such as incorrectly shaped metal tooth fillings, which systematically irritates mucous membranes), or even chronic mouth infection caused by yeast(Candida albicans).

Risk factors leukoplakia

The main risk factor in the case of leukoplakia smoking and alcohol. Another risk is the Epstein – Barr virus, which is in our population also expanded. Since yeast infections can be relatively well transferred between individual persons and get inter alia, in the oral cavity, she is also quite risky.

prevention leukoplakia

Preventive measure is to avoid smoking and excessive drinking of spirits. If we feel that we have something in your mouth regularly brushing the mucosa or know about loose dental fillings that irritate us, it is advisable to seek dentist. This is not only because of leukoplakia, but also to protect the tooth. The same applies if we have suspected for leukoplakia. This is not a acute illness, yet consultation with a specialist on the spot. When detected yeast infection, we should check the oral mucosa and other places, and when detecting white coatings on them to remind your doctor.Since this infection may be in the body is relatively well developed, should be doctor these problems always searched.

symptoms leukoplakia

The disease manifests itself whitish, sharply defined coatings on mucous membranes. They can be affected oral mucosa, external genitalia, but also the mucosa inside our body, such as the bladder mucosa. Another symptom is also excessive keratinization of the skin or its intensification.

treatment of leukoplakia

Leukoplakia usually disappear after administration of antifungals, or during antiviral therapy. It is possible to treat leukoplakia and cryotherapy (treatment in very cold environments) or surgically – a statue of the affected area. In this variation, treatment affected area this Delete and replaced by healthy tissue.

How to help treat leukoplakia

Treatment can help especially the observation seizure treatment. It is also recommended to avoid the possibility of transmission of yeast infection, which could only prolong convalescence or leukoplakia symptoms worse. But it is especially appropriate to observe preventive measures and suspicions of this disease, consult a doctor.

complications leukoplakia

Complications can occur, especially after surgical solutions. In particular the postoperative period, when they can occur at the surgical site infection, increased sensitivity or inflammation.
