Anatomical segmentations in all forms of vitiligo: A new dimension to the etiopathogenesis.

Background: We have reported segmented lesions in acral vitiligo as well as in generalized vitiligo and thereby proposed somatic mosaicism as a predisposing feature in all forms of vitiligo. This study is a further attempt to characterize and understand such segmented lesions by screening a large series of patients.

Methods: We searched our electronic archives (from 2002 to 2014) and identified/reviewed the photos of 615 vitiligo patients inclusive of all clinical types.
