Latex allergy is a known cause of allergic contact dermatitis. It produces mild symptoms, including skin rash and itching, which usually subside in a few days. However, latex allergy can also induce anaphylaxis, a severe type I hypersensitivity reaction. The diagnostic tools used for IgE-mediated latex allergy include history assessment, skin test, provocation test, and serological test. The best management technique is prevention, and the best preventive measure is avoidance.We report a case of anaphylactic shock during cesarean section surgery in a patient with no previous allergic history. A thorough work up revealed that the patient had a latex allergy.
