Aquagenic urticaria is a rare form of physical urticaria in which hives develop on the skin after contact with water, regardless of its temperature. It is sometimes described as an allergy, although it is not a true histamine-releasing allergic reaction like some other forms of urticaria. The condition typically results from contact with water of any type, temperature or additive.
The main symptom of aquagenic urticaria is the development of physical hives, which may or may not itch.
The hives associated with aquagenic urticaria are typically small (approximately 1–3 mm), red- or skin-colored welts (called wheals) with clearly defined edges. It most commonly develops on the neck, upper trunk and arms, although it can occur anywhere on the body. Once the water source is removed, the rash generally fades within 30 to 60 minutes.
Water in all forms, such as tap or sea water, swimming pool water, sweat, tears, and saliva can induce the lesions.
