Abstract

Aquagenic urticaria, a rare variant of chronic-inducible urticaria, is triggered by direct contact with water. It is distinguished by its characteristic small wheals accompanied by a halo of erythema from other forms of urticaria. It typically manifests with a delayed diagnosis due to the atypical trigger and the potential for diverse clinical presentations. We present a case of aquagenic urticaria in an adolescent male that demonstrates the need for accurate differential diagnosis and appropriate management.
