Thiurams are accelerants that are commonly used to manufacture natural rubber latex products. These mixes are present in natural or synthetic rubber products making up materials that are used either at work or at home. Many tire workers are sensitized to black rubber mix. Concerning nonoccupational exposure, it has been shown that black rubber footgear and the rubber tips of walking sticks can also cause contact dermatitis. Positive reaction to p-tertbutylphenol formaldehyde resin is related to contact with waterproof glue, bonded leather, and construction materials, whereas that to p-phenylenediamine is related to contact with permanent or semipermanent hair dyes, dyed textiles, and cosmetics; however, these are less relevant compared with our case. In conclusion, this report suggests that patients with HHE should be comprehensively evaluated through history taking and correctly treated by avoiding the suspicious material. ACKNOWLEDGMENT
