    Oral lichenoid lesions: distinguishing the benign from the deadly.
    Mod Pathol 2017 Jan;30(s1):S54-S67
    Professor Emeritus, Emory University School of Medicine: Atlanta Oral Pathology, Decatur, GA, USA.
    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

    VU medical center/ ACTA, Dept. of Oral and Maxillofacial Surgery/Pathology, Amsterdam, the Netherlands.
    Since its introduction in the literature in 1985, the term proliferative verrucous leukoplakia (PVL) has been the subject of an ongoing discussion with regard to its definition. Widespread or multifocal occurrence of oral leukoplakia is not just synonymous to PVL. In the present treatise the proposal is made to require the involvement of more than two oral oral subsites, a total added seizeof the leukoplakic areas of at least 3 centimeters, and a well documented period of at least five years of disease evolution being characterized by spreading and the occurrence of one or more recurrences in a previously treated area.

    Department of Otolaryngology-Head and Neck Surgery, The Johns Hopkins Hospital, 600 North Wolfe Street, Sheikh Zayed Tower, Baltimore, MD 21287, USA.
    Proliferative verrucous leukoplakia, a lesion of unknown origin with no strictly defined diagnostic criteria, is worthy of great clinical concern and scrutiny. Treatment options vary, with no consensus regarding the most efficient and effective strategy. Further complicating the unusual biology and behavior of this lesion is its usual multifocal presentation and progression, with lifelong vigilance required after treatment. Read More

    Urban legends series: oral leukoplakia.
    Oral Dis 2013 Oct 4;19(7):642-59. Epub 2013 Feb 4.
    Department of Surgical Sciences, Oral Medicine Section, Lingotto Dental School, University of Turin, Italy.
    To date, the term oral leukoplakia (OL) should be used to recognize 'predominantly white plaques of questionable risk, having excluded (other) known diseases or disorders that carry no increased risk of cancer'. In this review, we addressed four controversial topics regarding oral leukoplakias (OLs): (i) Do tobacco and alcohol cause OLs?, (ii) What percentage of OLs transform into oral squamous cell carcinoma (OSCC)?, (iii) Can we distinguish between premalignant and innocent OLs?, and (iv) Is proliferative verrucous leukoplakia (PVL) a specific entity or just a form of multifocal leukoplakia? Results of extensive literature search suggest that (i) no definitive evidence for direct causal relationship between smoked tobacco and alcohol as causative factors of OLs, (ii and iii) the vast majority of OLs follow a benign course and do not progress into a cancer, and no widely accepted and/or validated clinical and/or biological factors can predict malignant transformation, and (iv) the distinction between multifocal/multiple leukoplakias and PVL in their early presentation is impossible; the temporal clinical progression and the high rate of recurrences and development of cancer of PVL are the most reliable features for diagnosis.
