The most notable symptom of vitiligo is depigmentation of patches of skin that occurs on the extremities. Although patches are initially small, they often enlarge and change shape. When skin lesions occur, they are most prominent on the face, hands and wrists. Depigmentation is particularly noticeable around body orifices, such as the mouth, eyes, nostrils, genitalia and umbilicus. Some lesions have hyperpigmentation around the edges. In regards to psychological damage, vitiligo can have a significant effect on the mental health of a patient. Psychological stress may even result in an individual becoming more susceptible to vitiligo. Patients who are stigmatised for their condition may experience depression and similar mood disorders..
Non-segmental vitiligo
In Non-segmental vitiligo (NSV), there is usually some form of symmetry in the location of the patches of depigmentation. New patches also appear over time, and can be generalised over large portions of the body, or localised to a particular area. Vitiligo where little pigmented skin remains is referred to as ''vitiligo universalis''. NSV can come about at any age, unlike segmental vitiligo which is far more prevalent in teenage years.
