Sir, An unusual and potentially important facet of vitiligo is its relationship to malignant melanoma. The selective destruction of pigment cells that occurs in vitiligo can be regarded as a therapeutic goal sought in melanoma treatment. Thus, the association of vitiligo and melanoma is of special interest to dermatologists, immunologists, and oncologists, and vitiligo can be viewed as an exper...

BACKGROUND Vitiligo is a well-recognized pigmentary disorder of the skin and /or mucous membrane characterized by circumscribed ivory or chalky white macules devoid of identifiable melanocytes. The pathogenesis of vitiligo is complex and still not well understood. According to autocytotoxic hypothesis, oxidative stress has been suggested to be the initial pathogenic event in melanocyte degenera...

BACKGROUND/OBJECTIVES Prior studies have demonstrated that both the skin surface pH and epidermal permeability barrier function vary with skin pigmentation types. Although melanin deficiency is the main feature of vitiligo, alterations in cutaneous biophysical properties in vitiligo have not yet been well defined. In the present study, stratum corneum (SC) hydration, the skin surface pH and epi...

Progressive Childhood vitiligo is a common acquired de-pigmenting condition that can affect skin and hair with devastating psychological effects on patients as well as their parents. Children with vitiligo often suffer from anxiety and depression because of their unusual appearance. Management of progressive vitiligo in children is difficult as therapeutic options are restricted when compared t...

OBJECTIVE Vitiligo is a rare side effect of carbamazepine whose exact mechanism is unknown. The aim of this report is to describe a single case of vitiligo induced by carbamazepine. METHODS The case was a patient with Bipolar I disorder whose medications were changed from valproate to carbamazepine and who developed vitiligo after a short while. We followed the case for about four years when ...

Background. Lymphocytic dermal infiltrations accompany the melanocytes loss in depigmenting vitiligo skin. These lymphocytes are incriminated during the pathogenesis of the disease. Fas receptor is a death receptor on the surface of cells that leads to programmed cell death (apoptosis) and FasL is its ligand. Fas/FasL system plays a crucial role in modulating apoptosis. Objectives. This study i...

Gefitinib is a tyrosine kinase inhibitor that targets and inhibits epidermal growth factor receptors. It was initially used to treat non-small cell lung cancer but has increasingly been used for other solid tumors such as those in the breast, colorectal sites, and head and neck, as in our patient. Vitiligo is an autoimmune disorder that results in the destruction of melanocytes and subsequent s...

Background. Vitiligo is an acquired depigmentary skin disorder resulting from autoimmune destruction of melanocytes. Regulatory T cells (Tregs), specifically CD4(+)CD25(+) and Forkhead box P3(+) (FoxP3(+)) Tregs, acquired notable attention because of their role in a variety of autoimmune pathologies. Dysregulation of Tregs may be one of the factors that can break tolerance to melanocyte self-an...

INTRODUCTION AND OBJECTIVE Vitiligo is a chronic autoimmune skin disease caused by the destruction of melanocytes. Although quality of life (QOL) in vitiligo has been studied in different countries, it has not yet been investigated in Mexico. The aim of this study was to assess the QOL of Mexican patients with vitiligo. MATERIAL AND METHOD We conducted a cross-sectional study at the research ...

Vitiligo is a common depigmenting skin disorder, characterized by acquired, idiopathic, progressive, circumscribed hypomelanosis of the skin and hair, with total absence of melanocytes microscopically. It occurs worldwide, with an incidence rate of between 0.1% and 2%. Vitiligo is an important skin disease having a major impact on the quality of life of the patient suffering from it. The causes...
