Although the white color in leukoplakia is a result of hyperkeratosis (or acanthosis), similarly appearing white lesions that are caused by reactive keratosis (smoker's keratosis or frictional keratoses e.g. morsicatio buccarum) are not considered to be leukoplakias. Leukoplakia is being recognized by two forms: Homogeneous and the non-homogeneous type. 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 broadly classified into homogeneous and non-homogeneous subtypes.[2, 3] The distinction between this two types is purely clinical, based on surface colour and morphological (thick-ness) characteristics, and do have some bearing on the out-come or prognosis.

Homogeneous leukoplakia is a uniformly white flat plaque with a smooth or relatively smooth surface; non-homogeneous leukoplakia may be nodular or verrucous having a wrinkled or corrugated surface or may be a mingling of white and red areas termed erythroleukoplakia [7, 10, 11]. The clinical appearance of oral leukoplakia may change over time. A homogeneous leukoplakia on the left commissure extending posteriorly. In addition, typical alterations of potentially malignant lesions are seen co-existing in the margins of squamous cell carcinoma. Erythroleukoplakia can therefore be considered a variant of either leukoplakia or erythroplakia since its appearance is midway between. In general, the thicker the leukoplakia, the greater the chance of finding dysplastic changes; therefore, a verrucousleukoplakia is more likely to show dysplasia than is a thick homogeneous leukoplakia, which, in turn, is more likely to show dysplasia than is a thin leukoplakia.

Leukoplakias are commonly homogeneous and most are benign. Non-homogeneous leukoplakia, or so-called speckled leukoplakia or nodular leukoplakia - a predominantly white or white and red lesion (erythroleukoplakia) with an irregular texture that may be flat, nodular, exophytic, or papillary/verrucous - is more likely to be potentially malignant. What is Homogeneous Leukoplakia?

Leukoplakia is different from other causes of white patches such as thrush or lichen planus because it can eventually develop into oral cancer. Within 15 years, about 3% to 17.5% of people with leukoplakia will develop squamous cell carcinoma, a Leukoplakia is classified into two main types: Homogeneous type which appears as a uniform, flat white lesion altering or not with normal mucosa. Non-homogeneous type which includes speckled, nodular and verrucous leukoplakia. The speckled type is a red and white lesion, with a predominantly white surface. 2018-05-22 Homogeneous leukoplakia This variant of oral leukoplakia carries the lowest risk of malignant progression, with one study indicating the frequency of malignant development at 3% (compared with 20% of cases of non-homogeneous leukoplakias developing carcinomas). [124] Figure 12: Homogeneous leukoplakia (arrow) on the lower labial mucosa. Figure 13: Homogeneous leukoplakia on the right side of the dorsum tongue.

Figure 15: Homogeneous leukoplakia on the left lateral border of the tongue. 12 rows Homogeneous OL arises as a white patch slightly elevated, thin, white to gray, uniform, and can present well defined borders or may gradually mix with normal adjacent mucosa (Figure 1 to 3). Non-homogeneous OL can be nodular, verrucous, or speckled (erythroplastic) (Figure 4) [4,10]. Figure 1.

2019-12-06 · Homogeneous leukoplakia, which is the most common form, is manifested as a flat and uniform white plaque with a smooth surface and well-defined margins. Non-homogeneous OL appears as a white plaque and areas of erythema accompanied by areas that contain nodules and/or verrucous parts with ill-defined margins . Expand Fig 1. Leukoplakia is being recognized by two forms: Homogeneous and the non-homogeneous type.
