There are three major hypotheses for the pathogenesis of vitiligo that are not exclusive of each other: biochemical/cyt...

BACKGROUND Autoimmunity has been implicated in the destruction of melanocytes from vitiligo skin. Major histocompatibility complex (MHC) class-II linked genes proteasome subunit beta 8 (PSMB8) and transporter associated with antigen processing 1 (TAP1), involved in antigen processing and presentation have been reported to be associated with several autoimmune diseases including vitiligo. OBJE...

Vitamin D plays a role in the process of melanogenesis, namely increasing L-Dopa cells, inducing differentiation immature melanocytes, and melanocyte activity. The use vitamin dermatology is treatment vitiligo, psoriasis vulgaris, atopic dermatitis, verruca alopecia. Vitiligo an autoimmune disease skin form depigmentation due to destruction melanocytes by T cells. clinical manifestations vitili...

Vitiligo has been associated with the host's genetic profile, metabolic abnormality and immunostatus. The purpose of this study was to investigate the association of vitiligo with autoimmune diseases for 31 out of 39 subjects with vitiligo and their first-degree relatives living in a small Caucasian inbred rural community. They were compared with healthy individuals. A 2.28% prevalence of vitil...

INTRODUCTION Vitiligo is a common acquired pigmentary skin disorder. Vitamin D is responsible for skin pigmentation, increases tyrosinase activity and melanogenesis, and exhibits immunoregulatory functions. Low levels of vitamin D are associated with many autoimmune diseases, including systemic lupus, diabetes mellitus, rheumatoid arthritis, multiple sclerosis and alopecia areata. Few reports h...

Vitiligo is an acquired pigmentry disorder of the skin and mucous membranes which manifests as white macules and patches due to selective loss of melanocytes. Etiological hypotheses of vitiligo include genetic, immunological, neurohormonal, cytotoxic, biochemical, oxidative stress and newer theories of melanocytorrhagy and decreased melanocytes survival. There are several types of vitiligo whic...

Vitiligo is one of the most common pigmentary skin disorders; it is characterized by circumscribed depigmented macules due to the destruction of melanocytes. Although the etiology of vitiligo has not been fully elucidated, multiple factors including autoimmune and oxidative stress have been implicated in the pathogenesis of vitiligo. In contrast, dermal melanocytosis is histologically character...

Background: Vitiligo is a depigmenting disorder characterized by the loss of melanocytes. Thyroid functional disorders and autoimmune thyroid diseases have been reported in association with vitiligo. This study was thus conducted to find out any association of vitiligo with thyroid dysfunction. Methodology: This study was conducted at the Dermatology Department of a teaching medical college. Th...

The rarely seen eruptive syringoma (ES) is characterized by small, skin-colored, papules. Lesions are benign; however, treatment is often unsuccessful. Recent studies have a suggested role of the autoimmune response, rather than reactive proliferation of acrosyringium in the pathogenesis of ES. There are reports in the literature of an association between syringoma and diabetes mellitus as well...

Background: Vitiligo is a hypomelanotic autoimmune skin disorder arising from a breakdown in immunological self-tolerance, which leads to aberrant immune responses against melanocytes leading to selective destruction of melanocytes. High levels of Interleukin 1(IL1) have been reported in various autoimmune disorders including vitiligo. The aim of present study was to explore the effect of IL1-α...
