Clinical evaluation of the efficacy of trichloroacetic acid 70% after microneedling vs intradermal injection of 5-fluorouracil in the treatment of nonsegmental vitiligo; A prospective comparative study.

Abstract

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. According to the Physician's Global Assessment, there was no significant (P < .05) difference in the therapeutic response between the two studied groups. 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.
