What is Segmental Vitiligo?

Segmental vitiligo (SV) is a special form of vitiligo that has a unilateral distribution, usually along a single dermatome. Unlike the classical nonsegmental form, it is more common in children and adolescents, has a rapid onset and tends to stabilize within 1-2 years.

The pathogenesis involves sympathetic nervous system-related autoimmune mechanisms, neural factors and oxidative stress. It can affect the face, neck, trunk and extremities; whitening of hair and eyebrows may accompany.

SV is less associated with autoimmune diseases and responds better to surgical treatments (melanocyte transplantation). Pigmentation can be regained with topical and phototherapy treatments started at an early stage.

Symptoms

Unilateral dermatomal white patches
Rapid expansion of the lesion stopping after 1-2 years
Whitening of hair and eyebrows within the lesion
Absence of itching
Less family history of vitiligo
Onset usually in children and young adults
Involvement of face, trunk and extremities

Risk Factors

Younger age group
Trauma or friction (Koebner phenomenon)
Stress
Sympathetic nervous system variations
History of local infection
Oxidative stress

  • If unilaterally spreading white patches are noticed
  • If a child suddenly develops a hypopigmented plaque
  • If whitening of hair or eyebrows accompanies
  • If lesions are spreading or increasing in number
  • When aesthetic and psychological impact is significant
