Re-pigmentation of Vitiligo Involving Angle of Lip Using Radiofrequency Cautery and Topical 5-Fluorouracil.

Vitiligo involving the angle of lip is a therapeutically challenging site because of the small and delicate area, high mobility, and lack of hair follicles. Dermabrasion combined with topical 5-fluorouracil cream has shown promising results in various studies involving different sites. Here we present a novel technique of using radiofrequency cautery for abrasion of epidermis followed by application of 5-fluorouracil cream. This technique has the advantage of being simple, easy, cost-effective with less downtime. A single session can yield excellent pigmentation in small areas such as the angle of lip.
