The perilesional skin in vitiligo: a colorimetric in vivo study of 25 patients

Background: The aim of this work was to study in vivo the perilesional skin in vitiligo with a colorimetric method. Methods: Twenty‐five patients affected by vitiligo were included. For each patient, three different areas were considered: the lesional, the perilesional and the normal skin as far as 5 cm from the nearest vitiligo spot. Skin pigmentation measurements were performed with a chromameter. Results: The results showed that luminance L* decreased significantly in relation to increasing distance from the vitiligo spot. As expected, L* in the vitiligo spot was significantly higher than in the perilesional (P
