Lichenoid dysplasia is a lichenoid features with epithelial dysplasia clinically and histopathologically similar to oral lichen planus. It can be clinically mistaken for oral lichen planus, but has histopathologic features of dysplasia and a true malignant predisposition. The clinician should be able to differentiate between oral lichen planus and lichenoid dysplasia for the proper management. We experienced a 75-year-old man with erosive, erythematous lesion on the left buccal mucosa previously diagnosed as oral lichen planus. He underwent surgical excision and the final histopathological result confirmed it to be lichenoid dysplasia with massive candidal infection. We report this case with a review of the related literature.
