Proliferative Verrucous Leukoplakia; Erythroleukoplakia; Proliferative Verrucous Leukoplakia (PVL) It is an aggressive form of oral leukoplakia. It usually involves the gingiva & buccal mucosa. PVL initially flat in surface and then slowly enlarged. High risk of cancerous formation. Erythroleukoplakia verrucous leukoplakia frequently show severe dysplasia and greater tendency towards epidermoid carcinoma than the simple homogeneous leukoplakia in the oral cavity. On the basis of clinicopathological review, vander Waal et al.
Figure 3: Proliferative verrucous leukoplakia: multifocal involvement affecting … 2019-05-14 Homogeneous leukoplakia is a lesion of uniform flat appearance that may exhibit superficial irregularities, but with consistent texture throughout. On the other hand, non-homogeneous leukoplakia appears to be predominantly white or white and red Homogeneous leukoplakias: the most common type, are uniformly white plaques – common in the buccal (cheek) mucosa and usually of low malignant potential. Oral leukoplakia (leuko=white, plakia=patch) is a white patch in the mouth that There are two main types: homogenous and non-homogenous leukoplakia. The clinical finding of leukoplakia has been reported using various terms, but classification into two types is generally accepted: homogeneous and non-homogeneous leukoplakia, based on surface color and morphologic characteristics.

Leukoplakia is different from other causes of white patches such as thrush or lichen planus because it can eventually develop into oral cancer. 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. [6] Homogeneous plaques are predominantly white, of
Homogeneous leukoplakia is defined as a predominantly white lesion of uniform flat, thin appearance that may exhibit shallow cracks and has a smooth, wrinkled or corrugated surface with a consistent texture throughout.

In general, homogeneous leukoplakias are benign. Premalignant potential is higher in verrucous leukoplakias, and is highest in speckled leukoplakias.
Premalignant potential is higher in verrucous leukoplakias, and is highest in speckled leukoplakias. Clinical presentation Homogeneous leukoplakia is defined as a predominantly white lesion of uniform flat and thin appearance that may exhibit Non-homogeneous leukoplakia has been defined as a predominant white or white-and-red lesion ("eritroleukoplakia") that
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.

However, non-homogeneous leukoplakia is the The majority of re- searchers showed non-homogenous leukoplakia as a risk factor, although different terms have been used to describe these lesions.

Non-homogeneous OL can be nodular, verrucous, or speckled (erythroplastic) (Figure 4) [4,10]. Figure 1. Homogeneous thin leukoplakia in the tongue. Figure 2. There are three main types of leukoplakia: most are smooth plaques (homogeneous leukoplakias), some warty (verrucous leukoplakia) and some mixed white and red lesions (speckled leukoplakias).
possibly the most important is a non-homogeneous clinical appearance. The handpiece creates a large spotsize with a unique collimated homogeneous beam profile of Nd:YAG laser light.
