Urticarial Vasculitis in a Teenage Girl.

This case involves a 13-year-old female who presented to the pediatrician for a routine check-up with complaints of a long history of intermittent diarrhea followed by a severe rash lasting for up to a week afterwards. The mother had described her daughter's condition to multiple physicians, several whom had seen her during flare-ups. The nonmigratory lesions resembled "hives" with a single lesion lasting for 48 to 72 hours and resolving into what her parent described as a bruise. They often diagnosed her daughter with urticaria and prescribed steroids, which did resolve the acute flare-ups. None of the physicians, however, focused on the disease's evolution and chronicity in an effort toward diagnosis and prevention. The patient was referred by her pediatrician to a dermatologist who diagnosed the patient with urticarial vasculitis. She was initially started on dapsone 25 mg and was increased over a period of months to a maintenance dose of 100 mg daily. She has had no recurrences in her cutaneous or systemic symptoms on this dose. She is closely monitored by her dermatologist on a regular basis with twice yearly complete blood counts. Several attempts have been made to discontinue the dapsone, resulting in a flare of her gastrointestinal symptoms. This patient suffered with this condition for almost 10 years. This is a reminder that spending extra time to think through a patient's problem early on may prevent years of suffering for patients and their families.
