Contact urticaria caused by a fluorescent dye.
A 28-year-old man developed urticaria while he was working in the garage. We suspected contact urticaria, which can be caused by some products used in his field, and we carried out a prick test using his work gloves and shoes. His gloves were orange and black in colour, his shoes were black and white in colour, and the materials they were made of were unknown. The results of the prick test using the gloves and shoes were positive. Gas chromatography/mass spectrometry was applied, and a fluorescent dye was found to be present in his gloves and shoes. The results of a prick test using the fluorescent dye were positive. His urticaria improved after he stopped using these gloves and shoes. This was a rare case of contact urticaria caused by a fluorescent dye in clothing.
