Formulating a clinicopathological algorithm for oral lichenoid dysplasia and related lesions

The term OLD is used to designate a primary oral epithelial dysplasia with secondary lichenoid features [1]. An OLD may be unilateral or bilateral in the presentation. Can exhibit clinical patterns similar to the various types of oral lichen planus ranging from the most common reticular type to the rare bullous variant. OLD may also show features similar to oral leukoplakia (flat white patch). OLD histopathology consists of 2 components: epithelial dysplasia and lichenoid features. The dysplastic features may range from mild to severe based on the World Health Organization (WHO) grading of oral epithelial dysplasia [2].
