A 59-year-old woman presented at a dentist with swelling on the left side of the buccal mucosa hour and a half after temporary teeth was placed. The temporary teeth was removed a few hours later, when the woman developed a fever of 37.5℃, blisters on her palate and swelling on the pharynx that made breathing difficult. Patch tests revealed positive reactions to the temporary teeth, liquid resin, polymerized resin, 2-hydroxyethyl methacrylate（2-HEMA）, ethyleneglycol dimethacrylate（EGDMA）, gold sodium thiosulfate, potassium dichromate and mercuric chloride. However, there was no reaction to methyl methacrylate（MMA）which is the main component of acrylic resin. The liquid resin includes methacrylate monomers, which have a structure similar to that of 2-HEMA and EGDMA. Based on these result, we diagnosed a methacrylate resin allergy. There are fewer reported cases of methacrylate resin allergy in dental patients than in dental workers；indeed, there are just four, including this case, possibly because it is easy to overlook mild symptoms. It was important that we included 2-HEMA and EGDMA, not just the main agent in patch testing when we suspected a methacrylate resin allergy.
