A frequent immune-related adverse event of checkpoint-inhibitor (CPI) treatment, which manifests as depigmented spots on the skin is known Vitiligo-like depigmentation (VLD). The aim this study was to further characterize clinical, biological and prognostic features melanoma patients with VLD under CPI-treatment explore whether they exhibit a characteristic immune response profile in peripheral...

BACKGROUND In vitiligo, melanocytes are gradually lost in depigmented macules of the skin. The disappearance of melanocytes has, however, not been clearly observed and consequently the aetiology of the disease (autoimmune, neural, cytotoxic) is still elusive. The starting point of vitiligo macules is frequently determined by local conditions such as wounds and excoriations, but may also follow ...

background: vitiligo is an acquired, idiopathic disorder characterized by circumscribed depigmented macules and patches. the exact etiology and pathogenesis of vitiligo is not clear. many theories have been presented regarding this subject among them aautoimmune theory is the most important one. the association of vitiligo with other autoimmune disorders has been reported, but the relationship ...

Tumor antigen-reactive T cells can be detected in a large proportion of melanoma patients, but their efficacy on tumor control in vivo remains unclear. On the other hand, vitiligo, a skin disorder characterized by patchy depigmented macules, may occur spontaneously or after antitumor therapies. Moreover, vitiligo is significantly associated with positive clinical response, but the mechanism is ...

INTRODUCTION Vitiligo is an acquired, idiopathic disorder characterized by circumscribed depigmented macules and patches, which affects approximately 0.1-2% of the general population worldwide. Zinc is an essential trace element that is necessary for growth and development at all stages of life. Some studies have reported an association between serum zinc levels and vitiligo. AIM To measure t...

Background: Vitiligo is an acquired idiopathic pigmentary skin disorder characterized by sharply demarcated milky white macules with variable size and shape. It has an estimated worldwide incidence of 0.5-4% and occurs in half of the patients before the age of 20 years. Since exact pathogenic mechanism is unknown, several proposed hypotheses are alternation of cellular and humoral immunity, mel...

Pruritus with unknown origin is a common complaint and secondary causes should be investigated. We report a 22-year-old man with intractable localized pruritus and painful burning, stinging sensations in the bilateral arms, shoulders, neck and upper back for 3 weeks. A dermatologist was consulted in the emergency department. On physical examination, there were multiple excoriated erythematous m...

OBJECTIVE Vitiligo usually presented as asymptomatic depigmented macules and patches. Little is known regarding itch in vitiligo. This study aimed to evaluate the prevalence and characteristics of itch in vitiligo patients. PATIENTS AND METHODS A cross-sectional study was conducted on vitiligo patients. Itch character and intensity were determined through questionnaires. Evaluation was also m...
