Neville, Damm, Allen, Bouquot. Proposal for a set of modified WHO diagnostic criteria of oral lichen planus and oral lichenoid Lesions  Click here to view. The oral mucosa elsewhere was clinically normal.
Evolution of the lesion of discoid lupus dyspoasia In the present case, the lesion diagnosed as lichen planus clinically came out to dysplxsia LD histologically.
Some authors believe that lichenoid dysplasia should be considered as an injury with high likelihood of evolving to malignancy 13,15,18reinforcing even further the theory that most cases of lichen planus with possible evolution to malignancy stem from failed initial diagnosis.
Clinico-pathological mimicry and its diagnostic implications.
Oral manifestations of chronic mucocutaneous candidiasis: Total of ten cells were analyzed from each field. Lichenoid lesions of oral mucosa.
The concern around the malignant potential of oral lichen planus is much more related to diagnostic difficulties than to the nature of the condition itself. In view of malignant transformation, biopsy is mandatory licnenoid LD and erosive and atrophic forms of lichen planus. On the other hand, they also suggest that cell and nucleus pleomorphism is a highly relevant finding, as dysplqsia points to lichenoid dysplasia and consequently patients that require closer clinical follow-up.
Oral lichen planus versus epithelial dysplasia: difficulties in diagnosis
A simple and reliable biopsy technique. Proliferative verrucous leukoplakia and precancerous conditions In: Histopathological diagnosis of dysplasix lichen planus is not easy since some cases of epithelial dysplasia may present traits which are very similar to those from lichen planus. The chi-squared test did not show statistically significant differences between oral lichen planus and epithelial dysplasia in relation to the following cell alterations: Crit Rev Oral Biol Med ; 13 5: Eisenberg and Krutchkoff 11 reported that oral lichen planus is unlikely to evolve malignantly.
Reaching a diagnosis of oral lichen planus is no easy task due to the lack of accurate clinical and histopathologic criteria. Oral lichen planus in childhood.
Oral lichenoid dysplasia: a clinicopathologic analysis.
The lesion had irregular margins with slightly raised surface and measured around 1. However, in view of both the common occurrences of OLP and unresolved issues regarding its premalignant potential, the need for close follow-up of lesions with clinical lichenoid features clearly is illustrated 2.
Thus the parameters studied may have a value in predicting their behavior. Examiners looked at cell disorders indicative of malignancy and took the following criteria into account: Eisenberg and Krutchkoff suggested that some lesions diagnosed as lichen planus might have, in fact, been epithelial dysplasias with a clinical lichenoid appearance.
Classification of oral lichenoid lesions  Click here to view. Clinically, such lesions are usually unilateral and have a predilection for vermillion area, palate and buccal mucosa. Oral manifestations of erythema multiforme. Oral Surg oral Med Oral Pathol ; Three women had a diagnosis of oral lichen planus OLPwhich was made on the basis of clinical and histologic features. Nuclear Volume, V C: Today it is known that alterations to the normal epithelial cell maturation pattern are strongly correlated to lesions evolving malignantly.
J Oral Maxillofacial Surg ; Ayango L, Rogers RS 3 rd. Any histological findings showing dysplastic changes will make diagnosis as lichenoid dysplasia than oral lichen planus. Quantitative cellular and nuclear volumetric alterations in epithelium from lichen planus lesion and oral mucosa.
Lichenoid Dysplasia–A Case Report with a Review of Differential Diagnosis
They proposed that epithelial dysplasia with lichenoid features that is, LD is a distinct histopathologic entity with a true malignant predisposition.

It should not be neglected that the very chronic inflammatory process present in lichen planus leads to the onset of cell disorders that mimic the ones seen lichenoiv epithelial dysplasia, without however possessing any malignant connotation.
