A case of allergic contact dermatitis presented with acquired vitiligo-like depigmentation developed persistent light reactivity: Unforeseen entity

Abstract

Chemical leukoderma is an acquired depigmentary skin disorder, caused by repeated exposure to specific chemical compounds or secondarily to allergic contact dermatitis or through direct toxic effects, sharing similar clinical and histological features with vitiligo. We report a case of widespread allergic contact dermatitis with chemical leukoderma which later became a persistent light reactor.
