Oral lichen planus versus epithelial dysplasia: difficulties in diagnosis

Eisenberg and Krutchkoff suggested that some lesions diagnosed as lichen planus might have, in fact, been epithelial dysplasias with a clinical lichenoid appearance. The pathogenesis of these two lesions is entirely different – in lichen planus the lichenoid infiltrate represents cell mediated immune response incited by different antigens whereas in LD, it represents immune surveillance mechanism against atypical epithelial cells [ 2 ]. Mucosal erythema of obscure origin displaying spontaneous, usually temporary, dyspladia to complete regression may be common to both purely inflammatory conditions like lichen planus and early epithelial dysplasia.

Review and update on pathogenesis. Immune activation and chronic inflammation as the cause of malignancy in oral lichen planus: Although speckled erythroplakia was the earliest clinical sign of a classic, nonregressing premalignant lesion, it already signaled the presence of invasive carcinoma. World Health Organization Classification of Tumours. Additionally, some cell disorders indicative of malignant disease present in oral lichen planus may also be seen in epithelial dysplasia, thus making diagnosis even harder and consequently emphasizing the relevance of offering long term follow-up to patients with this disease, not because of its malignant potential, but due to possible mistakes made in the initial diagnosis.
