Case of Acute Annular Urticaria / 대한피부과학회지

ABSTRACT

Acute annular urticaria is a morphologic subtype of urticaria, characterized by the acute onset of annular, arcuate and polycyclic erythematous wheals. Angioedema of the face, hands and feet and dermographism are often associated. Systemic symptoms are usually limited to fever of short duration. Patients with acute annular urticaria are usually benefit from the oral antihistamine, and systemic corticosteroids are rarely required except in the most severe cases. Episodes usually resolve within 8 to 10 days. Acute annular urticaria is more common in infancy and early childhood. We report a case of acute annular urticaria in a 9-week-old male infant whose skin lesion developed 3 days after the vaccination against diphtheria and poliomyelitis.
