Sally is 17 years old and recently became bothered by a rash that is itchy, red, inflamed, and dry. She also has scaly areas that she says are getting worse. The rash is only around her umbilicus and on her elbows. Both of her parents have psoriasis, but she doesn't believe this is the problem, because it appears different from her parents' lesions. She lives in Florida, is under a lot of stress in high school, and just recovered from a lingering upper respiratory infection (URI).
