ABSTRACT
Vitiligo is a skin disorder commonly acquired. Although different therapies are used, they are refractory to therapy in many cases. Trauma has been reported to cause hyperpigmentation by the pigment incontinence, which results in the build-up of melanophages in the upper dermis after basal cell layer destruction. To detect the effectiveness of trichloroacetic acid (TCA) 70% in the treatment of nonsegmental vitiligo after skin microneedling by dermapen or intradermal injection of 5-fluorouracil. PATIENTS AND METHODS: A prospective comparative study was enrolled with 32 patients with vitiligo who were assigned to two equal groups. Each containing 16 patients; group 1 was treated by microneedling followed by TCA 70%, group 2 was treated by intradermal 5-FU injection. This was done every 2 weeks for 2 months. RESULTS: According to the Physician's Global Assessment, there was no significant (P < .05) difference in the therapeutic response between the two studied groups. CONCLUSIONS: Both microneedling plus TCA 70% and 5-FU intradermal injection are a simple means of treating vitiligo with cosmetically accepted repigmentation of all age groups, as well as a relatively safe alternative or additive method that can be used before (or in combination with) any of the well-known and widely approved method for stable nonsegmented vitiligo treatment.
