New definition proposed for oral leukoplakia

Leukoplakia is defined as “white plaques of questionable risk having excluded (other) known diseases or disorders that carry no increased risk for cancer.”[1] It is considered as a premalignant lesion and has a malignant transformation rate of around 0.13%–34%.[2] Hence, it is critical to recognize this entity. Over the decades, various classifications have been proposed in the literature for leukoplakia. However, still there is confusion and ambiguity in uniform reporting of this lesion.[3] Hence, there is a need to propose a new definition for leukoplakia for diagnosing and uniform reporting of this entity.
