Leucoderma secondary to wig wearing

Abstract

DEAR EDITOR, We reported a case of a 30-year-old Chinese man, without a personal or family history of leucoderma, developing a well-demarcated band of depigmentation without itching or erythema for 1 year, the shape of which was consistent with wig adhesives containing acrylate. He was diagnosed with chemical leucoderma, supported by a semiopen test, highly suspected to be acrylic induced. Chemical leucoderma, an acquired vitiligo-like depigmentation, is induced by repeated exposure to specific chemical compounds that are toxic to melanocytes. 1 It is important to quickly identify chemical composition when chemical-induced leucoderma is suspected, avoiding leucoderma after patch testing, especially with acrylate. 2
