Hello and thank you for your question. Vitiligo is an autoimmune condition that is due to a patient’s own immune system attacking their own pigment producing cells, resulting in white patches forming. Vitiligo is usually asymptomatic but can sometimes by itchy. Also it exhibits an interesting phenomenon called “Koebner’s phenomenon” where scratching or injuring neighbouring normal skin can lead to vitiligo patches appearing in them. Do see a Dermatologist for help with treatment of your vitiligo patches. Topical creams, light therapy or even cellular grafting can be helpful.
