The working group has defined OPMD as \u201cany oral mucosal abnormality that is associated with a statistically increased risk of developing oral cancer\u201d, including leukoplakia, proliferative verrucous leukoplakia, erythroplakia, oral submucous fibrosis, oral lichen planus, actinic keratosis\/actinic cheilitis, palatal lesions in reverse smokers, oral lupus erythematosus, dyskeratosis congenita, oral lichenoid lesions, and oral graft\u2010versus\u2010host disease.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A literature search was conducted to identify the available evidence on the malignant transformation of OPMDs.
