Types of Vitiligo

Vitiligo is a skin conditionin which a loss of pigment causes the skin to appear white (depigmentation). Irregular white patches may occur on any area of the body. Due to the difference between the affected and unaffected areas, this condition is more visible in people with darker skin. It affects 1% to 2% of the population and can affect anyone.

Vitiligo is classified into the following types:
Non-segmental vitiligo (NSV)
Subtypes are focal, mucosal, acrofacial, generalised, universal.
White patches are often bilateral and symmetrical.
Overlaps with other conditions which have known aetiology and are not classified as vitiligo.
Segmental vitiligo (SV)
Subtypes are focal, mucosal, uni-, bi- and pluri-segmental.
Rapid onset.
Unilateral.
Distribution may approximately match a dermatome.
Involves hair follicle depigmentation.
Mixed vitiligo (NSV + SV)
This is rare.
Unclassified

This category allows for a period of time of observation, after which a definitive classification can be made.
