Abstract
INTRODUCTION: Some therapeutic decisions in vitiligo depend on the likelihood of the disease remaining stable and inactive. AIM: To determine a period of disease stability in vitiligo following which reactivation was unlikely. MATERIALS AND METHODS: This cross-sectional descriptive study was carried out in 200 patients where a detailed clinical history of the disease activity and stability over the course of vitiligo was recorded. RESULTS: = 0.16). However, in non-segmental vitiligo, we found no association between the duration of stability and risk of reactivation. CONCLUSIONS: Segmental vitiligo usually becomes inactive after the disease has been stable for 2 years. Non-segmental vitiligo is prone to reactivation even after prolonged periods of stability.
