VITILIGO
Vitiligo is an acquired, often familial, melanocytopenic disorder that produces focal depigmentation of the skin.
About half of the patients has onset of lesion before the age of 20.
It is a progressive disease wherein spontaneous repigmentation may occur within 6 months.
Precipitating factors include emotional stress, sunburn, chemical exposure, skin trauma, inflammation, irritation or rash that may precede the lesions by 2-3 months.
Lesions are white-colored macules or patches with well-defined borders and otherwise normal skin surface.

Follow Up

Nonsegmental Vitiligo

  • NSV patients on narrow band UVB therapy should be reassessed on the 3rd & 6th mth of therapy
  • If still w/ disease progression after 3 mth of narrow band UVB therapy w/ topical steroid/calcineurin inhibitor therapy, consider switching to systemic corticosteroid therapy
    • After 3-6 mth, consider surgical interventions if disease is stable but w/o repigmentation, or depigmentation therapy if w/o repigmentation & w/ Koebner phenomenon
    • After 9 mth of narrow band UVB treatment, consider surgical interventions if disease is stable but repigmentation stopped

Segmental Vitiligo

  • Reassess patients on topical steroids & calcineurin inhibitors on the 6th mth of therapy
