The condition isn't contagious. DermNet provides Google Translate, a free machine translation service. the histopathological assessment was performed from the epidermis down and included these following features: epidermal changes (atrophy, hyperkeratosis, and hypergranulosis), interface changes (basal vacuolization and lichenoid dermatitis), superficial perivascular infiltration (mild, moderate, and severe), perifollicular infiltration/fibrosis, In this model, the initiation of suppressive IL-10-producing B cells is controlled by a TLR. In uncircumcised men, circumcision is usually recommended to avoid phimosis (14). Irla N, Schneiter T, Haneke E, Yawalkar N. Nail lichen planus: successful treatment with etanercept, Successful treatment of palmoplantar nail lichen planus with cyclosporine. [41] CD40 (the B cell-activating receptor) and the Toll-like receptors (TLRs) seem to contribute to the suppression function of B cells. Here, the prevalence of chronic inflammatory skin disease, including LP, was contrasted in over 23,000 patients with hepatitis C and a 3-fold greater number of non-hepatitis controls. 50. Oral antihistamines may be helpful to minimize the itch (14). Methodology: Eduardo Anitua, Laura Pias, Mohammad Alkhraisat. So far, only one mouse model has been established that resembles aspects of LP pathogenesis. It is not an actual lichen, and is only named that because it looks like one. (2, 3) Following this presumed injury, the loss of tolerance in LP occurs in the context of an association with the MHC that may additionally be shaped by associated viral infections and other environmental factors. This is particularly important in oral LP where painful erosions can result in significant malnutrition and weight loss. Mirza S, Rehman N, Alrahlah A, Alamri WR, Vohra F. Efficacy of photodynamic therapy or low level laser therapy against steroid therapy in the treatment of erosive-atrophic oral lichen planus. Chiang C, Sah D, Cho BK, Ochoa BE, Price VH. the display of certain parts of an article in other eReaders. Introduction. [28]. (g) Direct immunofluorescence microcopy staining with fibrin deposition in the epidermis (400 ). To better characterize the histopathology of oral lichen planus and oral lichenoid lesions and to highlight the differences between them in order to support the clinician in the diagnostic and therapeutic management of such conditions. The ePub format uses eBook readers, which have several "ease of reading" features More prospective studies are needed to assess this association. [11]. Intralesional steroid injections may improve response rates (161). Cutaneous LP tends to manifest during the fifth and sixth decades of life, with almost two-thirds of patients presenting with the disease between the ages of 30 and 60 years (9, 31, 32). Lichen planus is aT-cell mediated autoimmunedisorder in which inflammatory cells attack an unknownproteinwithin the skin and mucosalkeratinocytes. These include changes in the oral microbiome (e.g., Candida sp., various other bacterial infections) and dental metals precipitating allergic contact reaction (5457). Thus, a low diversity of cutaneous bacterial communities may generate a pro-inflammatory state, even under steady-state conditions, that shares features of LP (Figure 2); thereby, potentially lowering the threshold for LP to develop. Drug-induced LP should always be considered and excluded prior to commencing immunosuppressive therapy (14) and the responsible drug discontinued or substituted. Alsenaid A, Alamri A, Prinz JC, Ruzicka T, Wolf R. Lichen planus of the lower limbs: successful treatment with psoralen cream plus ultraviolet A photochemotherapy. 2013;149:1082.

Dr Aaron Sarwal Follow MDS Student (Conservative Dentistry and Endodontics) at National Dental College and Hospital Advertisement Recommended The appearance of lichen planus-like lichenoid dermatoses has been likened to the scurfy, finely furrowed, dry excrescences of the symbiotic vegetation known as lichen. LPLK is observed worldwide across all racial and ethnic groups; however, lighter-skinned individuals (especially Caucasians) are more prone to Large Cell Acanthomas than darker-skinned .

Lichen planus (LP) is a T cell-mediated disease affecting the stratified squamous epithelia of the skin and/or mucus membrane. Ries S, Hilgenberg E, Lampropoulou V, et al. If this is a solitary lesion, a benign lichenoid keratosis is favored. Oral lichen planus Furthermore, in 2 independent case series, tofacitinib used as either monotherapy or adjunctive therapy led to clinical improvement in 11/13 patients (95, 96). Lichen planus is a fairly common, itchy, non-infectious rash that usually occurs in adults. Clinically, it has specific and clearly identifiable features; bilateral symmetric presentation showing a lace-like network of fine white lines (known as Wickham's striae) is an essential element of OLP even if the lesion exhibits a mainly atrophic and erosive pattern. Setterfield JF, Neill S, Shirlaw PJ, Theron J, Vaughan R, Escudier M, et al.. Size ranges from pinpoint to larger than a centimetre.

The classical skin changes are pruritic, purple, polygonal, flat-topped (planar) papules crossed by fine white lines, while erosions are seen on the mucous membranes (Figure 1).

Functional evidence for a pathogenic contribution of IL-17, including the IL-17 pathway, stems from the observation of increased IL-17 and IL-23 expression in LP (84), as well as the clinical improvement following off-label treatment of LP patients with the anti-IL-17 antibody secukinumab, or the IL-12/23-targeting ustekinumab or the IL-23 inhibitor guselkumab.
