oral lichen planus is a chronic inflammatory immune-mediated disease. icam-1 and vcam-1 are vascular adhesion molecules that their receptors are located on endothelial cells and leukocytes. the aim of this study is the immunohistochemical evaluation of vcam1 and icam1 in oral lichen planus and to compare these two markers with normal mucosa for evaluation of angiogenesis. this descriptive-analy...

OBJECTIVE Lichen planus and lichenoid lesions affecting the oral cavity show similar clinico-pathological features creating a diagnostic dilemma. Hence, the aim of the present study was to establish a clinical and histopathological correlation in the diagnosis of oral lichen planus, based on the modified WHO diagnostic criteria of oral lichen planus and oral lichenoid lesions proposed by Van de...

Aim of the present investigation was to analyse the possible malignant transformation of oral lichen planus to carcinoma, especially in the atrophic erosive forms and those displaying plaques involving the top of the tongue. A review has been made of the literature, from 1986 to the present day. This search outlines the relationship between oral lichen planus, hepatitis C virus infection, Epste...

BACKGROUND Although oral lichen planus has been classified by the World Health Organization (WHO) as a potentially malignant disorder, such classification is still the target of much controversy. AIM To evaluate the cell proliferation rate in oral lichen planus, comparing it to the rate observed in epithelial dysplasia and oral squamous cell carcinoma, aiming at indications which might indica...

Background: Oral lichen planus is a potentially malignant disorder. One of the malignant transformation markers is cancer stem cells. One of the proposed marker for the detection of cancer stem cells's in head and neck cancer is aldehyde dehydrogenase. Recently it is shown that aldehyde dehydrogenase 1 expression in tissue samples is associated with oral lichen planus malignant transformation. ...

Oral lichen planus which is one of the most common oral mucosal diseases in adults, it has been rarely described in children. There are very reports in the literature regarding oral lichen planus in children, here we report a case of intraoral lesions of lichen planus. Lichen planus should be considered in the differential diagnosis of hyperkeratotic or erosive lesions of the oral mucosa in chi...

OBJECTIVES The purpose of this study was to evaluate the expression of cdk4 and p16, the proteins implicated in hyperproliferation and arrest in oral lichen planus and to compare their expression in erosive and non-erosive oral lichen planus and with normal mucosa and oral squamous cell carcinoma. MATERIAL AND METHODS Analysis of cdk4 and p16 expression was done in 43 erosive oral lichen plan...

oral lichen planus is diagnosed according to clinical and histopathological characteristics.some times all of the classical  histopathological features can not be seen.in some articles the presence of mast cells have been noted below the epithelium of oral lichen planus patients.the following study was done to evaluate the number of mast cells in the histopathological sections of 20 oral lichen...

AIM To determine the presence of circulating autoantibodies to desmoglein (Dsg) 1 and Dsg 3 in patients with oral lichen planus. METHODS Serum concentrations of circulating autoantibodies to Dsg 1 and Dsg 3 were determined by ELISA in 32 patients with erosive form and 25 patients with reticular form of oral lichen planus, 13 patients with acute recurrent aphthous ulcerations and 50 healthy co...
