Leukocytoclastic vasculitis mistaken for chronic idiopathic urticaria

Chronic urticaria is a commom health problem. Though not a rare disease, only part of these patients are correctly diagnosed and even fewer of them evaluated and treated in a proper way. Herein described, a case report of an old female with such diagnosis since 8 years ago. She suffered from multiple episodes of diffuse and itching hives and plaques evaluated by dermatologists and allergy specialists along these past years. Skin lesions of long lasting nature and pettechial appearance made this diagnosis reappraised and a skin biopsy was ordered. Vasculitis was shown. The bottom line: leukocytoclastic vasculitis mistaken for chronic urticaria is something to be considered when evaluating an apparent simple case of chronic idiopathic urticaria.
