Abstract
Acrylates can be the causative allergen in contact dermatitis to adhesives on the skin. The presence of acrylates in the adhesive, however, has to be confirmed. We present a case of an 81-year old male who developed contact dermatitis on his lower back at the same site where Transcutaneous electrical nerve stimulation (TENS) was applied continously for three years. Despite positive patch test reactions to several (meth)acrylates,they were not found to be present in the adhesive layer of the electrodes. Additional patch testing with the ingredients of the adhesive layer according to the material safety data sheet (MSDS), with extracts of the electrodes, and with thin-layer chromatograms were performed. The patient showed a positive patch test reaction to acrylic acid, and its presence in the electrode was confirmed with high-pressure liquid-chromatography-UV (HPLC-UV). A TENS electrode that did not contain either (meth) acrylates or acrylic acid was prescribed, after which the dermatitis disappeared.
