title: Chronic urticaria associated with bacterial infection. A case of dental infection.
abstract: In most cases of chronic urticaria, a specific etiology cannot be determined. This should not discourage the physician from continuing to search for its underlying cause. Infection has long been considered a cause of urticaria, although the incidence is probably low when all other common causes are considered. A case of chronic urticaria of five years duration, which was associated with chronic extensive dental infection and periodontal disease, is presented to show the importance of infection as a trigger mechanism of urticaria.
