H, Van der Waal I. The literature discussed in the article is an attempt to segregate individual lichenoid lesions by defining clinical and histopathologic variations among each other, which avoids the diagnostic problem. Controversies surrounding malignant transformation.

Histopathologically, subepithelial vesiculation, minimal lymphocytic infiltrate and perivascular cuffing of inflammatory cells distinguishes GVHD lesion from characteristic lichen planus. The possible pre malignant character of oral djsplasia planus and oral lichenoid lesions: This criterion can be used to differentiate OLP from lesions carrying a greater risk of malignant change 6.

Lichen planus is one of the most common dermatologic diseases to involve the oral cavity, with prevalence rates ranging from 0. In the present case, the lesion diagnosed as lichen planus clinically came out to be LD histologically. Materials and Methods Normal epithelium was obtained from patients undergoing extraction for impacted third molar with no sign of inflammation or any other pathology.

Histopathological diagnosis of oral lichen planus is not easy since some cases of epithelial dysplasia may present traits which are very similar to those from lichen planus. In view of malignant transformation, biopsy is mandatory for LD and erosive and atrophic forms of lichen planus. 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.

Ayango L, Rogers RS 3 rd. In case of LLs for which a distinct cause can be found warrants the removal of associated causative agent like drug, amalgam restoration.

According to them, many of the cases that eventually evolved to epidermoid carcinoma were actually lichenoid dysplasia cases wrongly diagnosed as lichen planus, given the large number of histopathologic similarities between both conditions, more specifically when in their early stages. They proposed that epithelial dysplasia with lichenoid features that is, LD is a distinct histopathologic entity with a true malignant predisposition.

However, if the clinical diagnosis is not verified by histological examination, or if the incipient dysplastic changes in the presence of lichenoid features are not recognized or are overlooked, a misdiagnosis could result.
