Halo nevi association in nonsegmental vitiligo affects age at onset and depigmentation pattern.

Objective: To compare factors associated with halo nevi with nonsegmental vitiligo (NSV) vs NSV alone.

Design: Prospective observational study in 553 patients with a confirmed diagnosis of NSV attending a vitiligo clinic between January 1, 2006, and July 1, 2010.

Setting: Vitiligo Clinic at the Department of Dermatology, University Hospital Center of Bordeaux, Bordeaux, France.

Segmental vitiligo associated with generalized vitiligo (mixed vitiligo): a retrospective case series of 19 patients.

Background: Mixed vitiligo (MV), the association of segmental vitiligo (SV) and nonsegmental vitiligo, has been rarely reported.

Objective: The aim of this study was to delineate the clinical spectrum of MV through a case series of patients with typical SV associated with patchy bilateral vitiligo.

Methods: This was a cross-sectional evaluation in the setting of a prospective observational study conducted in the vitiligo clinic of the department of dermatology in Bordeaux, France.
