Diagnostic criteria and their importance in alleged relationship to oral cancer. Thus LDs and LLs have propensity for transformation, but not the lichen planus and hence the differentiation between these comparably similar entities is licehnoid important [ 3 – 5 ].

It has also been suggested epithelial dysplasia with lichenoid features is a distinct histopathologic entity with a true malignant predisposition 2.
