Abstract
Acute urticaria is a frequent benign disease in children and is often secondary to
infections. Usually it is a self-limited histamine-dependent cutaneous condition marked by
transient, erythematous, and pruritic wheals and frequently by acral angioedema. A haemorrhagic
pattern characterised by annular and polycyclic lesions with central ecchymosis
is a possible presentation especially in young children and it can be so alarming as to
cause hospital admission. Establishing the correct diagnosis of acute annular urticaria (a
morphologic subtype of simple infectious urticaria recently referred as urticaria multiforme)
is important to prevent an unnecessary diagnostic work up. In an otherwise well-appearing
child erythema multiforme, serum sickness-like reaction and acute haemorrhagic oedema
of infancy are the principal differential diagnoses. A direct history and physical examination
can reliably distinguish all these conditions, avoiding laboratory investigations
and allowing appropriate treatment. Reassurance and oral non-sedating antihistamine
therapy are sufficient.
