Oral lichenoid dysplasia and exophytic oral verrucous hyperplasia: Mythical entities of oral pathology

The World Health Organisation (WHO) has replaced the terms oral precancerous lesions and conditions with “Oral potentially malignant disorders (OPMD).” The latter term aptly describes its wide anatomical distribution and emphasizes the fact that not all such disorders turn into malignancy [1]. OPMD presents in various forms ranging from a flat white patch to exophytic verrucous growth. Although most OPMDs have precise definitions and strict diagnostic criteria’s, the existences of a few lesions including oral lichenoid dysplasia (OLD) and exophytic oral verrucous hyperplasia (OVH) are still debated.
