What is Aquagenic Urticaria?

Aquagenic urticaria is a skin condition that causes the rapid development of hives in the skin when the skin comes into contact with water. This can make it difficult for some people to come into contact with water. Aquagenic urticaria is a type of physical urticaria. The hives are about 1 to 3 mm in size with clearly defined edges. These hives can occur anywhere in the body but are more commonly observed on the neck, the upper part of the torso, and the arms. Hives can start to develop within 30 minutes of contact with water.

Moreover, aquagenic urticaria can be diagnosed through medical history, physical examination, and water challenge tests. Furthermore, treatments for aquagenic urticaria include antihistamines, topical medication (oil-based emulsions), and phototherapy.

What is Aquagenic Pruritus?

Aquagenic pruritus is a skin condition that causes the skin to itch when it comes in contact with water without developing visible signs such as hives or rashes. It is also defined as intensive skin itching when water touches the skin. Aquagenic pruritus occurs without an apparent cause or as a symptom of another condition. Approximately two third of polycythemia vera patients have aquagenic pruritus. It may also occur with other medical conditions like chronic urticaria or hives, hypereosinophilic syndrome, myelodysplastic syndrome, and other blood cancers. The symptoms of this condition include severe itching, stinging, tingling, burning sensation after the water gets on the skin, and emotional stress.
