BACKGROUND: Subjective histopathology is currently used to diagnose oral squamous cell carcinoma (OSCC). We tested if abundances of a panel of microRNA could be an objective OSCC indicator. METHOD: Literature review enabled identification of 10 microRNAs associated with oral and head and neck malignancies. We extracted RNA from formalin-fixed paraffin embedded biopsies; 20 each with OSCC, dysplasia or histologically normal epithelium (HNE) and 10 with oral lichen planus (OLP)...

INTRODUCTION: MicroRNA (miRNA) 320a and vascular endothelial growth factor receptor 2 (VEGFR-2) expression as the angiogenic biomarkers might be therapeutic targets in Oral lichen planus (OLP). IL-6 and C-reactive protein (CRP) could be prognostic in OLP, dysplastic OLP and Oral squamous cell carcinoma (OSCC). Therefore, their salivary detections as the noninvasive tools were aimed in this study. MATERIALS AND METHODS: Histopathologic examinations were carried out to distinguish the patients with dysplastic OLP and OSCC...

Oral lichen planus (OLP) is a common T-cell mediated chronic inflammatory disease. Although the etiology is still unclear, present studies suggest that the composition of the oral microbiota and psychological problems are implicated in the etiology of OLP. The pathogenesis of OLP includes mainly antigen-specific and non-specific mechanisms. Antigen-specific mechanisms involve T-cell activation following antigen presentation and apoptosis of basal keratinocytes triggered by CD8(+) cytotoxic T cells, while non-specific mechanisms consist of matrix metalloproteinase over-expression and mast cell degranulation in OLP lesions...

Oral lichen planus (OLP) is a T-cell-mediated chronic inflammatory autoimmune disease affecting 0.1% to 4% of the world population. The WHO has already recognized it as an oral potentially malignant disorder. However, the reasons for the malignant transformation of OLP are far from being elucidated clearly. The purpose of this review is to clarify how the tumor-like microenvironment in OLP mediates its potentially malignant transformation. Areas covered: We review published articles on the microenvironment characteristics of tumors, the pathogenesis of OLP, and clinical studies of OLP...

Intralesional triamcinolone acetonide injection is indicated for multiple skin conditions such as keloid scars, alopecia areata, and hypertrophic lichen planus. Immediate hypersensitivity reaction remains uncommon. We report on a 24-year-old woman who had received multiple intralesional injections with triamcinolone acetonide (Kenacort) plus lidocaine for keloid scar treatment without any reaction for the previous 10 years. The immediate reaction occurred 15 minutes after injection, with numbness on her face and 5 minutes later with urticaria on her chest wall and upper extremities, together with hypotension (blood pressure of 90/60 mmHg)...

Oral lichen planus (OLP) is a chronic inflammatory disease regulated by T cell-mediated immune response. Autophagy and its major inhibitory pathway Akt/mTOR participate in T cell metabolism and homeostasis, which has been implicated in autoimmune diseases. In this study, the potential involvement of autophagy and its regulatory Akt/mTOR pathway were investigated in local T cells of OLP. The expression of Akt/mTOR pathway and autophagy-related proteins in OLP local lesions, as well as in T cells, were measured by immunohistochemistry and double-labeling immunofluorescence, respectively...

BACKGROUND: Liver enzymes appear to be involved in oral lichen planus (OLP), but it is not known whether the elevation develops concomitantly with exacerbations of disease. We compared the levels of serum hepatic aspartate (AST) and alanine (ALT) aminotransferases as markers of OLP exacerbation in patients with chronic hepatitis C from those with chronic liver disorders, seronegative for hepatitis C virus (HCV). METHODS: We studied 71 patients with OLP, (48 HCV seropositive and 23 HCV seronegative with chronic liver diseases) measuring AST and ALT...

The aim of this work was to evaluate the prevalence of TP53Arg72Pro mutations and their possible relationship with oral carcinoma and oral potentially malignant disorders in Argentine patients. A cross-sectional study was performed on 111 exfoliated cytologies from patients with oral cancer (OC), oral potentially malignant disorders (OPMD) and controls. The TP53Arg72Pro mutations were determined using conventional PCR. We evaluated univariate and multivariate study variables, setting p < 0.05. We found: (a) a low frequency of Pro72 variant in control group and a high frequency in OC and OPMD, as well in OC and oral leukoplakia (OL) diagnosis; (b) multivariate association among the TP53CC genotype and females over 45 years with no tobacco nor alcohol habits with oral lichen planus pathology; (c) multivariate association between the TP53GC genotype and males with alcohol and tobacco habits and OC and OL pathologies...

BACKGROUND: The treatment of erosive oral lichen planus represents a therapeutic challenge. Despite numerous existing remedies, some of these treatments display disappointed results. Since it is a chronic disease with no current cure, the best treatment should target mainly the reduction of the duration and severity of symptomatic outbreaks with minimal side effects. To date, corticosteroids remain the first choice of treatment for oral lichen planus (OLP) patients. Although, topical corticosteroids have been found to be the safest and the most successful agents in the treatment of OLP, their prolonged use may cause mucosal problems and may lead to systemic complications...

Graham-Little-Piccardi syndrome (GLPS) is a rare form of follicular lichen planus and comprises cicatricial alopecia of the scalp, noncicatricial alopecia of the axillae, and/or pubis and spinous follicular papules involving the trunk and extremities. We herein report a classic case of GLPS in a 49-year-old female. Uniqueness of our case is due to its additional features of frontal fibrosing alopecia (FFA). Although overlap between GLPS and FFA has been mentioned in literature, such numbers are scanty. Therapeutic response with oral steroid and retinoid is also far better in contrast to what is described in the existing literature...

Vulvo-vagino-gingival syndrome was described as a distinctive pattern of erosive plurimucosal lichen planus (LP), and it is a clinical triad of vulval, vaginal, and gingival LP. It can lead to sequelae such as vaginal and urethral stenosis which can have severe implications on the quality of life. We report a case of a 40-year-old female who developed urethral, vaginal, as well as anal stenosis as a result of long-term exclusive mucosal LP involving vulvo-vaginal and anal mucosa along with oral LP without any other cutaneous involvement...

OBJECTIVE: Oral lichen planus (OLP) presents with large numbers of T lymphocytes accumulating beneath the epithelium of the oral mucosa; however, its aetiology remains obscure. A potential role for an emerging novel T cell subset, Th9, in OLP has recently been suggested but remains to be clarified. The current aim was to investigate the expression and potential clinical significance of Th9 cells in distinct subtypes of OLP. MATERIALS AND METHODS: Peripheral blood samples were collected from 41 OLP patients and 18 healthy controls (HCs)...
