Aquagenic pruritus responding to intermittent photochemotherapy.
Aquagenic pruritus is a rare but distinct entity in which intense itching develops after contact with water, in the absence of cutaneous signs or underlying disorders that could explain the symptoms. The aetiology is currently unknown, and treatment difficult, with a poor response to antihistamines. Psoralen-ultra violet A (PUVA) photochemotherapy can be effective, but frequent maintenance therapy may be required to prevent relapse of symptoms. We present a patient with typical aquagenic pruritus who responded well to PUVA, and who has remained well controlled on infrequent maintenance.
