A Case of Cefotiam-Induced Contact Urticaria Syndrome

Abstract

Contact urticaria refers to a wheal-and-flare response which occurs on intact skin after application of a chemical. When contact urticaria is accompanied by systemic symptoms, it is known as the contact urticaria syndrome. We report a case of contact urticaria syndrome occurring in a 24-year-old nurse, due to occupational exposure to cefotiam. An open patch test showed a positive reaction to cefotiam.
