The Value of Adding Mini-oral Pulse Steroid Therapy in Preventing Peri-lesional Halo Post Non-cultured Epidermal Cell Suspension (NCES) in Cases With Stable Segmental and Non-acral Vitiligo.

Plain-language summary

The goal of this clinical trial is to learn if adding mini-oral pulse steroid therapy improves the results of non-cultured epidermal cell suspension (NCES) surgery in patients with stable vitiligo. It will also evaluate the safety of this treatment approach. The main questions it aims to answer are: * Does adding mini-oral pulse steroid therapy reduce the development of a perilesional halo after NCES surgery? * Does the addition of steroids improve the degree of repigmentation and overall treatment outcomes in vitiligo lesions? Researchers will compare NCES surgery with mini-oral pulse steroids to NCES surgery alone to determine whether the steroid therapy improves surgical outcomes. Participants will: * Undergo NCES vitiligo surgery for stable segmental or non-acral vitiligo lesions. * Be randomly assigned to receive either surgery alone or surgery plus low-dose oral mini-pulse dexamethasone therapy. * Attend follow-up visits and clinical assessments for approximately 4 months. * Receive excimer laser sessions twice weekly after healing and have standardized photographs and scoring assessments to evaluate repigmentation.
