Experimental photoallergic contact dermatitis to bisphenol A.

A single clinical report describes photoallergic contact dermatitis to bisphenol A, with subsequent persistent light reactivity, in a group of eight outdoor workers. In a mouse model we have induced photoallergic contact dermatitis to bisphenol A; sites of photochallenge reactions flared when later tested with UVA alone. Attempts to induce photoallergy to bisphenol A in guinea pigs failed.
