Segmental vitiligo is considered a subtype of vitiligo but thought of as a
separate entity than generalized vitiligo. It is marked by development of
circumscribed depigmented macules or patches. It is notably for early
presentation with unilateral distribution (lesions do not cross the midline) and
rapid stabilization. The underlying mechanisms is unclear for this condition,
unlike generalized vitiligo which is thought to be due to an autoimmune response
to melanocytes.
Segmental vitiligo looks like NSV but the term Focal is used because it is a limited area.
Segmental vitiligo has a different form; this condition spreads more rapidly but is considered more constant and stable than non-segmental. It is much less common and affects only about 10% of people with vitiligo.
Segmental vitiligo is more noticeable in early age groups, affecting about 30% of children diagnosed with vitiligo.
It is non-symmetrical and usually tends to affect areas of skin attached to nerves arising in the dorsal roots of the spine. It is more stable, less erratic and responds well to topical treatments.
Non-segmental vitiligo is the most common type of vitiligo and occurs in up to 90% of people who have the disorder.
Non-segmental vitiligo is the most common of the 2 types of vitiligo. It is often characterized by white patches that are generalized (seen anywhere on your body), symmetrical (if it’s on one side of your body, it’s in the same place on the other side. eg. both hands, both elbows, both feet, etc.) and increase in size over time.
