The word “Leucoderma” originated from Greek (Unani) “Leukos” meaning “white”, and “Derma” meaning “skin”. Leucoderma is often also called Vitiligo. It is a health disorder involving the cells that produce melanin, a chemical responsible for color. When these cells stop functioning, loss of pigmentation occurs which manifests itself in the form of blotches (usually on the skin but it may also affect other areas of the body such as hair, the inside of the mouth, and even the eyes). This otherwise harmless disorder is non-contagious; and it generally produces lighter spots on the body in dark skinned people and darker spots in light skinned people. This disorder is not age or gender specific. Please note that extreme cases of Vitiligo are not treatable.
