Things Like Vitiligo
Vitiligo is a chronic skin disease due to which white or light pink patches appear on the affected area of the personís body. It may also cause the hair on the affected areas to turn grey or white as well. Vitiligo occurs when melanocytes that are responsible for making pigment in the skin, die or are unable to perform their function. This is a common skin disorder that has affected 1-2% of the people from all around the world. Though, it can be confused with many other skin conditions, such as pigmentation, white scars and hypopigmentation, and more.
There are two main types of Vitiligo patterns, including segmental and non-segmental (generalized). Non-segmental Vitiligo pattern is more common in people, and it typically affects the areas surrounding body openings, fingers, toes, and bony areas. This type of Vitiligo can occur at any age, whereas segmental Vitiligo pattern is more prevalent in adolescents.

Nevus depigmentosus is a stable disease which is limited to a small area. It appears in the form of white spots on body. It increases with the growth of body. The main cause of this disease is the irregularity in the function of melanocytes which produce little pigments.
