Diagnostic Considerations

A potential diagnostic pitfall is the failure to consider a diagnosis of urticarial vasculitis in patients with lesions lasting longer than 24 hours, in patients with lesions associated with pain more than with itching, and in patients with lesions resolving with pigmentary changes or scaling.

In addition to the conditions listed in the differential diagnosis, other problems to be considered include the following [30] :

  • Chronic infantile neurologic cutaneous articular syndrome
  • Familial cold autoinflammatory syndrome
  • Melkersson-Rosenthal syndrome
  • Muckle-Wells syndrome
  • Reticular erythematosus mucinosis
