Vitiligo is an asymptomatic but cosmetically disfiguring disorder that results in the formation of depigmented patches on skin and/or mucosae. Vitiligo can be segmental or non-segmental depending upon the morphology of the clinical involvement. It can also be classified as progressing or stable based on the activity of the disease. Further, the extent of involvement can be limited (localized disease) or extensive (generalized disease). The treatment of vitiligo therefore depends on the clinical classification/characteristics of the disease and usually comprises of 2 strategies...

Clindamycin is a lincomycin-derived antibiotic useful for the treatment of anaerobic and Gram-positive aerobic bacterial infections. Cutaneous adverse reactions are usually maculopapular exanthemas, although hypersensitivity syndrome, acute generalized exanthematous pustulosis, and Stevens-Johnson syndrome have also been reported (1). We report the case of a patient with a maculopapular rash triggered by clindamycin who developed cutaneous lesions on striae distensae (SD). A 47-year-old woman was referred to our clinic for pruritic cutaneous lesions which had started 6 days earlier...

Vitiligo is the most common acquired hypopigmentary disease in the community. Piperine as an herbal extract derived from black pepper has strong impact on the melanocyte proliferation and adverse side effects less than synthetic drugs such as corticosteroids. For the first time, this study was aimed to evaluate the effect of topical piperine combined with narrowband ultraviolet B (NB-UVB) on vitiligo treatment. In this double-blind clinical trial, 63 patients with facial vitiligo were randomly divided into 2 groups: treated with piperine (case) and placebo (control)...

Vitiligo commonly affects children, with half of affected individuals experiencing disease onset before the age of 20. Because childhood is a time of advancement in social and psychological development, understanding the extent of the effect of the disease and means of alleviation is crucial. Vitiligo has been shown to decrease children's quality of life, with greater distress in children with highly visible lesions and darker skin tones. This article reviews the literature regarding interventions that have been analyzed in children...

There is growing evidence to suggest that Th cells play pivotal roles in a variety of chronic inflammatory diseases, including vitiligo. However, the exact role of different subsets of Th cells in the pathogenesis of vitiligo is still a question. The purpose of present study was to determine the mRNA expression level of Th17 master transcription factor retinoic acid receptor-related orphan receptors gamma (RORɣt) and cytokine mRNA and protein expression profiles of Th17 cells. 22 patients with vitiligo and 22 normal subjects were enrolled in the study...

Background: Lip vitiligo is usually resistant to medical modalities of treatment, and in all these cases, surgery offers a hope. Suction blister grafting (SBG) has been tried since long for lip vitiligo with high rate of success. There have been no long-term follow-up studies of patients with SBG at a difficult-to-treat site like angles of lip, which prompted us to conduct this study. Aims and Objectives: To assess the pigmentation rate and patient satisfaction of SBG on vitiligo involving angles of lip...

Genital lichen sclerosus et atrophicus is an uncommon genital dermatosis. Its resemblance to vitiligo especially during the earlier stages leads to delay in its diagnosis. Apart from the common complications such as meatal stenosis, balanoposthitis, phimosis and painful erections, squamous cell carcinoma (SCC) is a rare but ominous complication of genital LSA. Herein, we present a case of long standing penile LSA complicated by SCC stressing upon the requirement of early diagnosis and management of LSA.

The role of epidermal keratinocytes in the pathogenesis of vitiligo has been ignored despite the fact that both melanocytes and keratinocytes form one functional and structural unit. Aquaporin3 (AQP3), a glycerol water channel expressed in epithelial tissue, is involved in the regulation of keratinocyte proliferation, cell migration, and has a potential role in hypopigmentation in vitiligo. Normally, acral skin differs significantly from non-acral skin. Acral skin shows significantly lower hair follicle density, melanocyte density, Langerhans cell (LC) density, epidermal MHCII expression...

BACKGROUND: Vitiligo is an autoimmune skin disorder in which the loss of melanocytes is mainly attributed to defective autoimmune mechanisms and, lately, there has been more emphasis on autoinflammatory mediators. Among these is the macrophage migration inhibitory factor, which is involved in many autoimmune skin diseases. However, little is known about the contribution of this factor to vitiligo vulgaris. OBJECTIVE: To determine the hypothesized role of migration inhibitory factor in vitiligo via estimation of serum migration inhibitory factor levels and migration inhibitory factor mRNA concentrations in patients with vitiligo compared with healthy controls...

IL-22 has been implicated in the pathogenesis of vitiligo. However, the role of aryl hydrocarbon receptor transcription factor that acts as a master regulator of IL-22-producing Th22 cells is not fully understood. The goal of this study was to investigate the expression pattern of aryl hydrocarbon receptor in peripheral blood mononuclear cells of patients with vitiligo and in normal controls. Transcript levels were determined by a reverse transcription quantitative real-time polymerase chain reaction. Aryl hydrocarbon receptor mRNA expression was drastically increased in patients with vitiligo compared to healthy controls (P = 0...

Melanocyte stem cells (McSCs) and mouse models of hair graying serve as useful systems to uncover mechanisms involved in stem cell self-renewal and the maintenance of regenerating tissues. Interested in assessing genetic variants that influence McSC maintenance, we found previously that heterozygosity for the melanogenesis associated transcription factor, Mitf, exacerbates McSC differentiation and hair graying in mice that are predisposed for this phenotype. Based on transcriptome and molecular analyses of Mitfmi-vga9/+ mice, we report a novel role for MITF in the regulation of systemic innate immune gene expression...

Vitiligo is characterized by progressive loss of skin pigmentation. The search for etiologic factors has led to the biochemical, the neurologic and the autoimmune theory. The convergence theory was then proposed several years ago to incorporate existing theories of vitiligo development into a single overview of vitiligo etiology. The viewpoint that vitiligo is not caused only by predisposing mutations, or only by melanocytes responding to chemical/radiation exposure, or only by hyperreactive T cells, but rather results from a combination of etiologic factors that impact melanocyte viability, has certainly stood the test of time...

Vitiligo is a disorder of the skin that causes depigmentation and asymptomatic macules whose exact cause is still unclear. Although its etiology is not fully elucidated, the main theory of its pathomechanism is that it is associated with the autoimmune process. There is few summarized information about the role of inflammatory mediators, as interleukins, in vitiligo. So, our aim was to present a systematic review of the role of interleukins in vitiligo, focusing on interleukins. In this review, we included all studies assessing interleukin levels in vitiligo patients conducted up to June 2017...

Skin is a protective organ and the largest of the human body. Due to its pivotal role in aesthetic appearance, skin health has a significant impact on quality of life. Chronic inflammation of the skin often marks the beginning of various skin diseases. Immune-mediated responses serve to protect the body from external insults and require succinct control, and can lead to ongoing cellular damage and various skin conditions if left unchecked. Studies have shown that phytochemicals can alter processes involved in skin inflammation and alleviate the effects of aging, cancer, atopic dermatitis, psoriasis, and vitiligo...

To protect the human skin from extensive solar radiation, melanocytes produce melanin and disperse it via melanosomes to keratinocytes in the basal and suprabasal layers of the human epidermis. Moreover, melanocytes are associated with pathological skin conditions such as vitiligo and psoriasis. Thus, an in vitro skin model that comprises a defined cutaneous pigmentation system is highly relevant in cosmetic, pharmaceutical and medical research. Here, we describe how the epidermal-melanin-unit can be established in vitro...
