Oral lichen planus

Erosive oral lichen planus (OLP) is a challenging disease. This T cell driven disorder frequently shows a treatment unresponsive course and strongly limits patients' quality of life. The disease lacks FDA or EMA approved drugs for its treatment and the efficacy of the commonly administered treatments (i.e. topical and systemic steroids, steroid sparing agents) is often only partial. Although the etiopathogenesis of the disease still needs to be fully elucidated, recent advances helped to identify interferon-ɣ (IFN-ɣ) as a pivotal cytokine in OLP pathogenesis, thus making the interference with its signalling a therapeutic target...

Buccal lichenoid lesions (BLLs) are characterised by a unique, linear whitish striation in the buccal region and can be accompanied by ulcers, plaques, erythemas, atrophies and blisters. They are distinguished from oral lichen planus (OLP) by the association of the administration of a drug or contact with a metal. Herein, we present the case of a 42-year-old woman with underlying hypertension with amlodipine-induced BLLs. She complained of a 1-month history of right buccal whitish streaks and oral ulcers 2 months after taking amlodipine...

Compelling evidence indicates that dyslipidemia is positively associated with oral lichen planus (OLP). The types and magnitude of lipid metabolism disturbance in peripheral blood of OLP patients have been investigated in different studies. Yet, consensus on how these different lipid components varied in levels for the development of OLP lesions has not been reached so far. Herein, a total of 8 eligible studies were recognized, which enrolled 533 cases of OLP and 499 healthy controls. The analysis showed that the average total triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) levels were considerably higher, and high-density lipoprotein cholesterol (HDL-C) levels were significantly lower in OLP patients compared to healthy controls...

Erosive oral lichen planus (EOLP) represents a significant challenge in dental and medical management due to its chronic inflammatory nature, painful symptoms, and impact on quality of life. This study aims to evaluate the current diagnostic approach with novel non-invasive techniques, such as dermoscopy, and also the landscape of treatment options for EOLP, focusing on its efficacy, safety, and the challenges that it present in clinical practice. Through a comprehensive literature review, we explored the use of topical corticosteroids, systemic immunosuppressants, biologics, and Janus kinase (JAK) inhibitors in treating EOLP, alongside examining patient compliance, psychological impacts, and the risk of adverse effects and recurrence...

OBJECTIVES: This study aimed to compare the efficiencies of 0.05% clobetasol propionate, 0.1% triamcinolone acetonide, and 5% amlexanox in the management of oral lichen planus (OLP). MATERIAL AND METHOD: A total of 120 patients diagnosed with oral lichen planus were equally divided into three groups and treated with 0.05% clobetasol propionate (group A), 0.1% triamcinolone acetonide (group B), and 5% amlexanox (group C) topical medicaments. The patients were evaluated for pain using the visual analog scale (VAS) and erosive lesion...

Oral cancer is detected in 270,000 people per annum or around 3% of all malignancies. It ranks sixth among males and twelve among females in terms of prevalence. Mostly, all oral squamous cell carcinomas (OSCC) are responsible for 92-95% of cases. Oral carcinoma starts five years before the average age of PMD patients, who range in age from 5th to 6th decade of life. Thus, the goal of this study is to identify any relevant risk factors and assess the incidence of oral possibly malignant disorders in both men and women living in rural Bhojpur District, Bihar...

BACKGROUND: Chronic mucocutaneous symptoms are a hallmark of lichen planus (LP), an inflammatory disease of the stratified squamous epithelium. The most severe type of mucosal lichen is oral erosive lichen planus (OELP). MATERIALS AND METHODS: Thirty patients were included in this prospective trial, with fifteen patients each assigned to Group A and Group B. Patients were given a choice between a placebo gel and an ayurvedic gel comprising pure turmeric, Calendula officinalis, and tulsi powder in an oral basis...

Background: Oral potentially malignant disorders (OPMDs) are a group of chronic oral mucosal diseases associated with an increased risk of malignant transformation. Multiple studies have investigated the prevalence of these conditions in multiple regions; however, there are limited data about the prevalence of OPMDs in the Kingdom of Saudi Arabia (KSA). This paper aims to review the prevalence of OPMDs in the KSA, to ensure better understanding of the population risk and propose a more standardised approach to the diagnosis and management of this group across the KSA...

The aim of this article is to report clinical features and therapeutic approach of cicatrizing keratoconjunctivitis secondary to ocular lichen planus based on a case report. The patient is a 77-year-old female with a history of ocular discomfort and recurrent keratoconjunctivitis that did not improve with conservative treatment, as well as a history of oral and nasal aphthous ulcers. After a complete ophthalmologic, dermatologic and anatomopathological study, the diagnosis of ocular lichen planus was established and immunosuppressive treatment was initiated...

Bone augmentation is often required before the installation of dental implants. Here, we report a case for a patient who previously received bone augmentation at the upper right jaw using a xenogenic graft, followed by successful implant installation. Seven years later, the patient presented with mucosal fenestration with bone exposure at the area and gave a history of a recent diagnosis of cutaneous lichen planus. Several attempts were made to manage the situation, and finally, we resorted to connective tissue graft placement at the site...

BACKGROUND AND AIMS: Oral lichen planus (OLP) is an inflammatory mucocutaneous disorder with an immune-mediated pathogenesis. The tumor necrosis factor-α (TNF-α) level in the serum of OLP patients is significantly higher than in the control group. TNF-α-857 C/T polymorphism can be related to the increased TNF-α level in blood circulation. This study investigated the relationship between TNF-α (-857 C/T) polymorphism and OLP patients in an Iranian population...

MATERIALS AND METHODS: This was a comparative prospective interventional study and the study was conducted among 50 patients presented to the Department of Otorhinolaryngology with premalignant oral lesions from the year 2020 to 2022...

AIM: Oral lichen planus (OLP) is a T-cell-mediated chronic inflammatory disease classified as an oral potentially malignant disorder (OPMD) and increased transformation risk to oral cancer. Oral lichenoid reactions (OLRs) share the clinical manifestations of OLP. This study aimed to determine histomorphometric changes in OLPs and OLRs in comparison to the healthy control, which helps to plan for the establishment of diagnostic criteria. MATERIALS AND METHODS: This cross-sectional prospective study was conducted on a total of 75 tissue-embedded paraffin-block samples, including OLPs (n = 25), OLR cases (n = 25), and healthy control individuals (n = 25)...

With the rise of Janus kinase (JAK) and Signal Transducer and Activator of Transcription (STAT) inhibitor use in dermatologic conditions, there has been increasing hope in treating extensive and difficult-to-treat inflammatory cutaneous conditions. Today we report a case of oral lichen planus successfully treated with an oral JAK1 inhibitor, upadacitinib. This case had been unresponsive by several standard methods but responded with 70% improvement within 1 month when treated with upadacitinib.  J Drugs Dermatol...

OBJECTIVE: γδ T cells are a distinct subset of unconventional T cells, which link innate and adaptive immunity by secreting cytokines and interacting with other immune cells, thereby modulating immune responses. As the first line of host defense, γδ T cells are essential for mucosal homeostasis and immune surveillance. When abnormally activated or impaired, γδ T cells can contribute to pathogenic processes. Accumulating evidence has revealed substantial impacts of γδ T cells on the pathogenesis of cancers, infections, and immune-inflammatory diseases...
