Proliferative verrucous leukoplakia (PVL) is a rare and refractory form of oral mucosal leukoplakia of unknown origin, characterized by high rates of malignant transformation. Different diagnostic criteria, terminologies, and therapeutic approaches have been proposed since the first report in 1985. There remains no general agreement regarding the clinical and histological diagnosis, prevention, and correct management of this disease. Read More

Importance: Potentially malignant disorders of the oral cavity (OPMD) are a heterogeneous group of lesions associated with a variable risk of malignant transformation (MT) to invasive cancer. Leukoplakia (LE), lichen planus (LP), oral lichenoid lesions (OLL), oral erythroplakia (OE), oral submucous fibrosis (OSF), and proliferative verrucous leukoplakia (PVL) are among the most common of these lesions. Oral dysplasia is a mucosal area characterized by cellular and architectural derangement, which may be associated with OPMDs or not. Read More

This report describes a case of proliferative verrucous leukoplakia (PVL) of the gingiva with no discernible aetiology, which presented in a 36-year-old female. The initial nonscrapable gingival lesion was treated with CO laser ablation, and the histopathological evaluation was carried out. The presence of koilocytic cells in the superficial epithelium led to immunohistochemical investigations with p16 antibody, which showed strong nuclear positivity and slight cytoplasmic positivity in >50% of the cells with >25% confluency.

There is a distinct lack of uniformity in the definitions and clinical terminologies related to oral leukoplakia and leukoplakialike lesions and disorders. Proposals have been put forward to subclassify leukoplakia into a homogeneous and a non-homogeneous type based on color only, being either predominantly white or mixed whiteand-red, respectively, irrespective of the texture of the lesion. In this proposal there is no need anymore to regard the poorly defined proliferative verrucous leukoplakia as a separate entity. Read More

Objective: Proliferative verrucous leukoplakia is classified as a potentially malignant disorder because of its high rate of malignant transformation. PVL progresses in a series of clinical stages where the early stage represents multiple, multifocal leukoplakias with a high recurrence rate. The intermediate and late stages are clinically exophytic lesion, diagnosed microscopically as verrucous hyperplasia that often progresses into verrucous carcinoma and/or squamous cell carcinoma.

Background: Oral cancer is said to be the 6th most common cancer in men and 12th in women. Potentially malignant disorders/potentially premalignant oral epithelial lesion (PMDs/PPOELs) have shown an increased risk of progressing to cancer. In this regard, lack of awareness about identification of oral PMDs among healthcare providers in general and oral pathologists in particular is said to be responsible for the diagnostic delay.

Background: Proliferative verrucous leukoplakia, recently coined as proliferative leukoplakia (PL), is associated with a strong tendency to recur after treatment and an elevated rate of malignant transformation. We compared the clinical characteristics of patients with gingival PL with and without progression to oral squamous cell carcinoma.

Methods: The patients were divided into two groups: group 1 included 33 patients with gingival PL that did not progress to cancer, and group 2 included 30 patients with PL who developed malignant transformation during follow-up. Read More

The use of diverse terminology may lead to inconsistent diagnosis and subsequent mistreatment of lesions within the proliferative verrucous leukoplakia (PVL) spectrum. The objectives of this study were: (a) to measure inter-observer variability between a variety of pathologists diagnosing PVL lesions; and (b) to evaluate the impact of diverse terminologies on understanding, interpretation, and subsequent treatment planning by oral and maxillofacial surgeons (OMFS). Six oral pathologists (OP) and six head and neck pathologists (HNP) reviewed 40 digitally scanned slides of PVL-type lesions. Read More

Proliferative verrucous leukoplakia (PVL) is a premalignant condition of the oral mucosa with > 70% chance of progression to squamous cell carcinoma (SCC), while lacking the common risks and behavior seen in non-PVL oral squamous carcinogenesis. PVL follows a multi-stage slow, relentless and usually multifocal expansion of surface epithelial thickening that over time takes on a verrucous architecture, eventually leading to verrucous carcinoma and/or dysplasia followed by "conventional" SCC, a process that takes years and is notoriously difficult to manage. As mucosal surfaces and carcinomas arising at these sites, are colonized by microorganisms, host receptors for microbial products have received attention as potential contributors to carcinogenesis.

Harvard School of Dental Medicine, Boston, MA, USA.

Leukoplakia and erythroplakia are two entities under the moniker of "oral potentially malignant disorders" that are highly associated with the presence of oral epithelial dysplasia (OED) at first biopsy, while lesions of submucous fibrosis develop OED after being present for years. Importantly, traumatic/frictional keratoses are often mistaken clinically for leukoplakia and it is important for the pathologist to recognize and report them as such. The features of OED have been well-described and other architectural features will be discussed here, in particular verrucous and papillary architecture, bulky epithelial proliferation and epithelial atrophy.

Verrucous hyperkeratosis (VH), verrucous carcinoma (VC) and the relentless, truly pre-malignant variant proliferative verrucous leukoplakia often exhibit lichenoid histologic features that may create a diagnostic dilemma for pathologists. This study aims to evaluate and categorize the frequency and the histopathologic patterns of lichenoid features seen in these lesions. Following IRB approval, cases of VH and VC from 1994 to 2014 were retrieved from the archives of UF Oral Pathology Biopsy Service. Read More

The second article in this continuing medical education series discusses the clinical and histopathologic features of common premalignant and malignant lesions of the oral cavity. It is imperative for dermatologists to be able to appropriately recognize suspicious lesions, determine the need to obtain a biopsy specimen, counsel, and refer patients presenting with premalignant or malignant conditions. Given the higher rates of mortality and morbidity of oral mucosal malignancies because of late diagnosis, appropriate treatment with multidisciplinary care in a timely manner is essential to patients with these neoplasms.

Proliferative verrucous leukoplakia (PVL) is a potentially premalignant lesion that undergoes malignant transformation in over 40% of cases. Its clinical homogeneity suggests that a single or a small number of molecular pathogenic pathways may exist. Using the Cochrane protocol for systematic reviews, we have looked at the reported evidence of the molecular aetiology and pathogenesis of PVL and compared it with that of conventional oral epithelial dysplasia (OED).

Background: Proliferative verrucous leukoplakia (PVL) is an oral potentially malignant disorder, characterized by multifocal expression, progressive clinical evolution, and a high rate of malignant transformation. Evidence-based information regarding optimal PVL management is lacking, due to the paucity of data.

Oral lichen planus is a chronic inflammatory disease of unknown etiology or pathogenesis with varied disease severity that waxes and wanes over a long period of time. Although a common oral mucosal disease, accurate diagnosis is often challenging due to the overlapping clinical and histopathological features of oral lichen planus and other mucosal diseases. Other immune-mediated mucocutaneous diseases can exhibit lichenoid features including mucous membrane pemphigoid, chronic graft-versus-host disease, and discoid lupus erythematosus. Read More

Proliferative verrucous leukoplakia (PVL) is a rare form of oral leukoplakia, which was first described in 1985 by Hansen et al. Since then, various published case series have presented PVL as a disease with aggressive biological behavior due to its high probability of recurrence and a high rate of malignant transformation, usually higher than 70%. PVL is a long-term progressive condition, which is observed more frequently in elderly women, over 60 years at the time of diagnosis. Read More
