Late patch test reaction to acrylates in a dental worker.
A dental technician developed eyelid and hand dermatitis. She had been previously patch-tested elsewhere with a sample of an acrylic material from a nail salon that reportedly was positive only after 1 month. Repeat testing with ethyl acrylate and methyl methacrylate gave no reaction at 48 or 96 hours, but became positive 5 weeks later. This very late reaction is probably a true allergic manifestation and not a case of active sensitization.
