Cutaneous signs of dioxin exposure.

Cutaneous stigmata of exposure to the halogenated compounds, including dioxin, may be the most sensitive index of exposure. The most common skin findings include chloracne, hyperpigmentation and hirsutism. Dioxin exposure may occur in a number of ways, in industrial, military and accidental settings. The cutaneous signs of dioxin exposure should prompt a careful evaluation for associated systemic disorders.
