The distribution of disease activity signs shows a discrepancy between segmental and non-segmental vitiligo. The new study also detected hotspots for the presence of different activity signs, such as the Koebner phenomenon and hypochromic areas. As the course of depigmentation in vitiligo is difficult to foresee, the possibility of determining skin signs of activity may be helpful for disease management [1]. A study by Dr Liesbeth Delbaere and colleagues (Ghent University Hospital, Belgium) aimed to establish the prevalence of confettiā€like depigmentation, the Koebner phenomenon, and hypochromic areas/borders [2]. An association to clinical activity was found for these signs that are included in the Vitiligo Signs of Activity Score (VSAS) [3]. The study included 503 vitiligo patients, of whom 446 had non-segmental and 57 had segmental disease [2].
