Chemical leukoderma mimics vitiligo and arises after chronic exposure to specific chemical compounds (phenolic and catecholic derivatives) with demonstrated cytotoxicity to melanocytes. Tyrosinase-related protein-1 facilitates cytotoxicity by catalytic conversion of the compounds, resulting in the generation of radical oxygen species. This report describes 4 cases of chemical leukoderma, 2 caused by contact with personal accessories and 2 caused by occupational exposure to chemicals.
