Background: Lichen planus is a chronic inflammatory disease ofunknown etiology that may involve mucocutaneous tissues. Themain aim of our study was to evaluate the frequency of oral andgenital lichen planus in men and women affected by skin lesions.Method: A total of 132 patients with clinical and histopathologicaldiagnosis of lichen planus were evaluated for oral and genitalinvolvement. All da...

The potential for malignant transformation of oral lichen planus is still controversial. The expression of proteins related to cell proliferation and apoptosis in oral lichen planus and epithelial dysplasia was analyzed to evaluate the true potential for malignant transformation of this disease. Twenty-four cases of each lesion were subjected to the streptoavidin-biotin technique for identifyin...

OBJECTIVES Biologic therapy such as Etanercept, which is a tumor necrosis factor alpha (TNF-α) inhibitor, has been extensively used as election therapy in rheumatoid arthritis. The purpose of this case presentation was to inform about the possibility that lichen planus lesions could potentially become complicated by secondary infections in patients treated with Etanercept. Furthermore, we aimed...

INTRODUCTION Cigarette smoking is related to many pathological conditions; however, chemical substances affect the oral cavity first, so it is important to consider its influence on oral mucosa and oral potentially pre-malignant lesions. The aim of this study was to investigate the effect of smoking on microvessel density in oral lichen planus. Special emphasis was placed on examining the relat...

Oral lichen planus is a chronic inflammatory disease that affects the mucous membrane of the oral cavity and can contribute to the development of other diseases. Inflammation in oral lichen planus is a T-cell-mediated autoimmune disease that acts through cytotoxic CD8(+) T cells to trigger apoptosis of keratinocytes. However, the specific cause of oral lichen planus remains unknown and no effec...

Lichen planus pigmentosus-inversus (LPP-inversus) is an extremely rare variant of lichen planus (LP), and only a few cases have been reported. Its course is characterized by exacerbations and remissions, and it is known to be more chronic than classical LP is. We report two cases of LPP-inversus and offer the suggestion that LPP-inversus may originate from LP of flexural areas.

We present the case of a 72-year-old Caucasian woman with frontal fibrosing alopecia of one year's duration. Eighteen months later, she presented with sudden hyperpigmentation on the submental area, neck and upper chest. Histopathological examination was consistent with lichen planus pigmentosus. This is the report of a unique case of a FFA and extrafacial lichen planus pigmentosus.

Lichen planus is an inflammatory, mucocutaneous disease that in addition to the skin involves oral mucosa in about 60-70 % of cases. In recent years, several reports have supposed a relationship between oral lichen planus (OLP) and chronic liver disease, especially hepatitis C (HCV). Here we present an extensive review of the literature in English that examines the association between HCV and OLP.
