Clinical Application Questions

A 48-year-old woman is seen for intensely pruritic raised lesions on her trunk and extremities of 3 weeks' duration. Clinically her lesions look to you like hives.

1. What questions should you ask the patient about the lesions to support your suspicion?

2. Would this most likely be classified as acute urticaria, chronic urticaria, or chronic intermittent urticaria, and why?

3. Assuming this is acute urticaria, what history should be sought to establish a possible cause?

4. Assuming this is acute urticaria, what laboratory studies are indicated?

5. What is the appropriate treatment at this point?

6. What is the prognosis for acute urticaria?
