Corn contact urticaria in a nurse.
A 33-year-old nurse presented with persistent hand dermatitis. Radioallergosorbent tests showed moderate to strong reactions to latex, avocado and banana. Despite avoidance of latex gloves, she failed to improve. Patch testing was negative. Prick testing showed a negative reaction to latex, but a strong reaction to corn, with relevance to cornstarch powder present in many medical examination gloves. She was diagnosed with corn contact urticaria, irritant contact dermatitis and type I hypersensitivity to latex fruits.
