Official Title: Natural History of Urticaria Pigmentosa in Children
Brief Summary: The purpose of this study is to determine how long the skin lesions usually last and what kind of symptoms and signs children with urticaria pigmentosa may develop over the years. This information will allow physicians to better care for patients who have been diagnosed with this disease and to provide their parents with more complete information regarding what to expect for the future of their child. This research is being done because many unanswered questions remain regarding children with urticaria pigmentosa and its course.
