The main symptom of leucoderma is white patches on the skin. The patches that affect the skin look can be small or large, depending on the patterns. Vitiligo has two common patterns, they are segmental or focal and non-segmental or generalized. The white patches with a segmental or focal pattern come with a smaller size. Not only that but the pattern only appears on a few areas of the body. Meanwhile, the white patches with non-segmental or generalized patterns tend to widespread in all areas of the body and look asymmetrical. This non-segmental leucoderma is usually more progressive than the segmental one.
