INTRODUCTION Oral lichen planus (OLP) is one of the most common dermatologic diseases that manifests in the oral cavity. The purpose of this study was to evaluate the association between smoking habits and the clinical subtypes of OLP. METHODS Oral findings and smoking data from 187 charts of OLP patients from an oral medicine clinic was reviewed and compared to data from 76 matched control p...

Oral lichen planus (OLP) is a chronic inflammatory disease of the oral mucosa which is considered by the World Health Organization (WHO) as a premalignant condition. One step in malignant development is so called epithelial mesenchymal transition (EMT), a process whereby epithelial cells acquire mesenchymal characteristics. A factor known to induce EMT is the transforming growth factor-β (TGF-β...

Introduction: Oral Lichen Planus (OLP) is one of the most common mucocutaneous lesion, and its etiologic factors have not been elucidated yet. OLP has two different clinical forms including reticular and erosive. Mast cells function in non-specific immunology is an etiologic factor involved in the formation of lichen planus. This study aimed at determining the pattern of mast cells presence in ...

Introduction: Oral lichen planus (OLP) is a chronic immunological disorder with unknown etiology. Some studies have reported an association between oral lichen planus and diabetes mellitus. The aim of this study was to compare the frequency of diabetes mellitus in patients with oral lichen planus and healthy persons. Materials & Methods: This case ‒ control study was performed on 50 patients...

it has been argued that oral lichen planus (olp) may increase the risk of oral cancer. patients with olp may be at an increased risk for developing of oscc (oral squamous cell carcinoma). here, the author reports a case of olp initially presenting with a clearly benign olp lesion that transformed into oscc over a course of 18 months. this report may provide a clear evidence for olp lesion as a ...

Both antigen-specific and non-specific mechanisms may be involved in the pathogenesis of oral lichen planus (OLP). Antigen-specific mechanisms in OLP include antigen presentation by basal keratinocytes and antigen-specific keratinocyte killing by CD8(+) cytotoxic T-cells. Non-specific mechanisms include mast cell degranulation and matrix metalloproteinase (MMP) activation in OLP lesions. These ...

OBJECTIVE To investigate the epidemiological and clinical characteristics of a relatively large cohort of patients with oral lichen planus (OLP) from eastern China. STUDY DESIGN A total of 518 patients with histologically confirmed OLP in a long-term follow-up period (6 months-21.5 years) were retrospectively reviewed in our clinic. RESULTS Of the 518 patients, 353 females and 165 males wer...

BACKGROUND China has been one of the countries with high prevalence of chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) liver disease. And lichen planus is an extrahepatic manifestation of patients with chronic HCV infection. This case-control study was conducted to investigate the relationship between oral lichen planus (OLP) and HBV/HCV infection in China. MATERIAL AND METHODS A ...

introduction: oral lichen planus (olp) and oral lichenoid lesions (olls) are clinically and histopathologically similar lesions but with different etiologies and treatment plan, thus differentiatingthese two has been the center of many researches. studies in different populations have beenperformed on clinical and histopathologic features of olp and olls. thus aim of the present studywas to eva...
