Oral lichen Planus(OLP) is a chronic mucocutaneous autoimmune disease that mostly affects middle-aged females. Various factors including psychological stress , drugs and various systemic conditions has been linked to the etiopathogenesis of OLP. It has got several variants including reticular, erosive, atrophic and ulcerative-types. Erosive and atrophic variants have been most often linked to i...

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...

A number of genetic, congenital and acquired dermatoses have been known to follow Blaschko's lines. A common disorder like lichen planus can very rarely present with pruritic lesions in atypical patterns such as unilateral distribution, painful eruptions and along Blaschko's lines. Various triggering factors varying from viral infections and vaccinations to trauma have been implicated in lichen...

Lichen planus pigmentosus is a rare subtype of lichen planus. We report a first case of lichen planus pigmentosus with bilateral linear distribution associated with hepatitis C virus infection. The lesion was improved after sun avoidance and treatment of hepatitis C virus infection with a combination of interferon and ribavirin. This case stresses the importance of screening for hepatitis C vir...

INTRODUCTION Lichen planus is a chronic, inflammatory, autoimmune skin condition that can affect the skin, mucosal surfaces, and nails. Mucosal lichen planus might occur in conjunction with or without cutaneous involvement. Current treatment options include both topical and systemic medications. Tacrolimus (FK-506 or fujimycin) is a macrolide immunosuppressant that inhibits calcineurin. Topical...

We describe a fifty-six-year old, Afro-descendent female patient showing dystrophy of her twenty nails and hyperchromic, asymptomatic macule on her face. Histopathological examination of the macule showed vacuolization of the basal layer, melanophages in the superficial dermis and lymphoplasmocytic inflammatory infiltrate. Nail biopsy revealed orthokeratotic hyperkeratosis and lichenoid inflamm...

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...

AIM Unstimulated whole salivary p53 was assessed in patients suffering from erosive and plaque-like form of oral lichen planus (OLP). MATERIALS AND METHODS Eighteen patients with erosive form, 17 patients suffering from plaque-like form and 38 noninvolvement subjects were enrolled. The unstimulated whole saliva p53 level was assayed by ELISA. RESULTS The mean concentration of salivary p53 w...

Lichen planus is a chronic, autoimmune, mucocutaneous disease that shows differences in clinical presentation at different times of the year. The present retrospective study was conducted to clarify the meteorological factors that influence the incidence of lichen planus, as well as the general features and clinical presentation of this condition during three consecutive years, 2008, 2009, and ...
