Focal vitiligo: long‐term follow‐up of 52 cases

Abstract

Focal vitiligo is a rare subtype of vitiligo and most patients have long-lasting focal lesions after onset of the disease. In this study, focal vitiligo progressed to typical non-segmental vitiligo, but not towards typical segmental vitiligo. Progression 2 years after onset of focal vitiligo, occurs in 50% of the patients with eventual progression to non-segmental vitiligo. There seem to be no clinical signs that predict progression in focal vitiligo.
