background and aims. oral lichen planus is a common chronic inflammatory disease of the oral mucosa with malignant potential, pathogenesis of which is not still well known. free radicals and reactive oxygen species can play an important role in the pathogenesis of oral lichen planus. the aim of this study was to investigate salivary oxidative stress and antioxidant systems in patients with oral...

Lichen sclerosus, lichen planus, and lichen simplex chronicus are three of the most common non-neoplastic epithelial disorders of the vulva. Lichen sclerosus is characterized by intense vulvar itching and can affect men and women of all ages, but it manifests most commonly in postmenopausal women. Patients with lichen sclerosus have an increased risk of developing squamous cell carcinoma, and t...

iichen planus is a relatively common disease of unknown etiology that occurs on the skin and oral mucosa. Compared with skin lesions, the mucosal affections have a far more chronic nature and often persist for many years (1). Because of the morbidity associated with these oral lesions and their propensity for malignant development (2), oral lichen planus occupies an important place in dental pr...

In a recently held WHO workshop it has been recommended to abandon the distinction between potentially malignant lesions and potentially malignant conditions and to use the term potentially malignant disorders instead. Of these disorders, leukoplakia and erythroplakia are the most common ones. These diagnoses are still defined by exclusion of other known white or red lesions. In spite of tremen...

OBJECTIVE To assess the association of lichen planus with liver complaints and with known aetiological factors of liver diseases. DESIGN Multicentre case-control study. Interviews were conducted by trained medical investigators on the basis of a structured questionnaire. At the interview patients and controls were asked for consent to blood samples being taken to determine transaminase activi...

BACKGROUND AND AIMS Lichen planus is a relatively common chronic mucocutaneaous disease with an unknown cause, and is considered a manifestation of cell-mediated immune response. Hepatitis C virus (HCV) and its subgroups have been associated with lichen planus in different geographic locations. The present study was undertaken to evaluate the prevalence of HCV antibody in patients with lichen p...

Background and objective: Given the postulated the role of inflammation and possible contribution of lymphangiogenesis in oral lichen planus, this study aimed to assess any associated presence of VEGFR-3. Material and Methods: This cross-sectional study was performed on 52 formalin fixed and paraffin embedded blocks of oral lichen planus (pathological diagnosis based on Modified WHO criteria), ...

OBJECTIVES Although several detailed studies concerning the patient profile and clinical features of oral lichen planus have been undertaken all over the world in different populations, a similar study has not yet been conducted in a Turkish population. The purpose of this retrospective study was to describe the demographic and clinical characteristics of a group of patients with oral lichen pl...
