World Vitiligo Day takes place on June 25, 2017. The World Vitiligo Day is an initiative aimed to build global awareness about vitiligo, a frequent and often disfiguring disease that can have significant negative psychosocial impact on patients, also because of numerous misconceptions still present in large parts of the world.
Vitiligo is an acquired disease characterized by skin depigmentation, due to destruction or malfunction of melanocytes (cells that produce melanin). It is present worldwide, and its prevalence in different countries ranges from less than 0.1% to more than 8% of general population (~1% in the United States and in Europe); thus, it can be estimated that approximately 100 million people in the world are affected.
