A Case of Aquagenic Urticaria / 대한피부과학회지

ABSTRACT

Aquagenic urticaria is a rare form of physical urticaria. It is manifested as pruritic multiple erythematous maculopapular eruptions mainly on the neck, chest and upper extremities by direct water contact. We report a 15-year-old male with urticarial lesions on the chest and both arms for 3 months. The lesions occurred 20 minutes after showering, irrespective of the water temperature. His symptom was temporarily controlled by oral antihistamines with UVB irradiation or PUVA therapy.
