Abstract:
Characteristic features of acute annular urticaria in 34 infants and small children were large, erythematous annular and polycyclic lesions with violaceous centers, eyelid, hand, and foot edema, absence of angioedema of the airway, absence of pruritus, spontaneous resolution in 8 to 10 days, and frequent history of furazolidone medication for diarrhea. Nondermatologists often misdiagnose acute annular urticaria as erythema multiforme and unnecessarily overtreat patients. The differential diagnosis with other conditions presenting with annular lesions in children is discussed.
