Oral leukoplakia (leuko=white, plakia=patch) is a white patch in the mouth that There are two main types: homogenous and non-homogenous leukoplakia. Leukoplakia is a firmly attached white patch on a mucous membrane which is associated with an increased risk of cancer. The edges of the lesion are typically abrupt and the lesion changes with time. Advanced forms may develop red patches. There are generally no other symptoms. It usually occurs within the mouth, although sometimes mucosa in other parts of the gastrointestinal tract, urinary nodular leukoplakia, 16% had ulcerated leukoplakia, and 52% had homogeneous leukoplakia.

Homogeneous leukoplakia ppt

The presence of an erythematous component (erythroleukoplakia) seems to convey a greater risk for MT. Leukoplakia is defined as a white patch or plaque that cannot be ascribed to any other clinical disease. Leukoplakia has long been known to be a precancerous lesion for oral squamous cell carcinoma. The rate of malignant transformation is not definitively known, but reports in the literature range widely from 0.13% to 17.5%. Clinically, different forms of leukoplakias exist; homogeneous leukoplakia is characterized by a flat and uniform white plaque with well-defined margins (at least one). Non-homogeneous leukoplakia presents with areas of erythema accompanied by areas of nodular-ity and verrucousity (van der Waal, 2010). Oral proliferative verrucous Homogeneous leukoplakia on the left buccal mucosa extending to the buccal sulcus, where betel quid is usually placed. Developmental white patches usually are present from birth or become apparent earlier in life, whilst leukoplakia generally affects middle aged or elderly people.

Leukoplakia has long been known to be a precancerous lesion for oral squamous cell carcinoma. The rate of malignant transformation is not definitively known, but reports in the literature range widely from 0.13% to 17.5%. It is well accepted that nonhomogeneous leukoplakia is associated with a higher risk (4- to 7-fold) for MT compared to homogeneous lesions [1–3]. The presence of an erythematous component (erythroleukoplakia) seems to convey a greater risk for MT. Homogeneous leukoplakia on the left buccal mucosa extending to the buccal sulcus, where betel quid is usually placed.

Homogeneous leukoplakia has predominantly white lesion of uniform flat, thin appearance, smooth, wrinkled or corrugated surface throughout the lesion, whereas non-homogeneous leukoplakia has been a mixture of Leukoplakia is marked by the formation of white or gray thickened patches on mucous membranes of cheeks, gums or tongue. The cause for Leukoplakia is still not known. However, it is mainly linked to usage of tobacco and consumption of alcohol. Hairy kind of Leukoplakia is observed during HIV infection which is caused by Epstein-Barr virus. homogeneous leukoplakia the lesion is uniformly white and the surface is flat or slightly wrinkled. In non-ho-mogeneous leukoplakia there is a mixed white-and-red color (“erythroleukoplakia”); the surface may be flat, speckled or nodular.

Brouns et al. (2013) found that 52.7% had homogeneous leukoplakia and 47.27% cases had non-homogeneous leukoplakia. The reasons for the higher incidence of homogenous leukoplakia in the present study are difficult to explain as they are multifactorial.

Oral proliferative verrucous leukoplakia (PVL) is a distinct subset of non-homogenous leukopla-kia. PVL may involve a single large site, but is frequently multifocal Non-homogeneous leukoplakia has been defined as a predominant white or white-and-red lesion ("eritroleukoplakia") that may be either irregularly flat, nodular ("speckled leukoplakia) or exophytic ("exophytic or verrucous leukoplakia"). These types of leukoplakia are often associated with mild complaints of localised pain or discomfort. Nevertheless, Schoelch et al.
