The possible pre malignant character of oral lichen planus and oral lichenoid lesions: From the above results and by comparing them with each other, enlargement of cell dimension can be noticed. Clinical management and malignant transformation. Published online May 1. J Oral Pathol Med. Histologically, the inflammatory infiltrate with predominant eosinophils is more widely spread deep into the connective tissue. OLP has been considered a premalignant condition requiring a recall program and proper follow up, which require substantial economic resources and is a potential problem in developing nations like ours.

J Oral Med ; Histologically, a characteristic Periodic Acid Schiff PAS stained positive material is seen along the basement membrane and around the blood vessels. Studies carried out in a number of countries found a considerably high likelihood of injuries initially diagnosed as lichen planus becoming malignant lesions along the years.

Clinical features and management. It does not imply dysplastic changes in lichen planus. Furthermore, this condition needs to be diagnosed with dtsplasia strict Clinico-pathologic criterion, which might reduce or possibly eliminate confusion about possible premalignant character of OLP and OLL oral lichenoid lesions 4.

Clinical management and malignant transformation.

Squamous cell carcinoma arising in an oral lichenoid lesion. 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 ].

None, Conflict of Interest: J Am Dent Assoc ; The results lochenoid in this study make it evident that the histopathologic diagnosis of oral lichen planus, mainly when differentiated against epithelial dysplasia, is quite difficult, as some cell disorders indicative of malignant disease such as increased nuclear-cytoplasmic ratio, nuclear hyperchromatism, and dysplassia chromatin distribution may be seen in either of the lesions.

The question about premalignant potential of OLP has been mired by controversy.

According to these authors, the cases of development to malignancy described in the literature are related to a condition with distinct histopathologic characteristics known as lichenoid dysplasia. Need of the study OLP has been considered a premalignant condition requiring a recall program and proper follow up, which require substantial economic resources and is a potential problem in developing nations like ours.
