Cutaneous and systemic sequelae from exposure to 2-vinylpyridine

We present the case of an employee of a chemical production factory who became sensitized to 2-vinylpyridine despite wearing full protective polyvinyl chloride clothing. He developed severe dermatitis at the site of contact, secondary eczematization over the flexures and periungual areas, as well as marked systemic upset. Pyridines are known sensitizers although this reaction pattern has not previously been described.
