    Description Hypersensitivity angiitis, also known as leukocytoclastic vasculitis, is an inflammation of the small blood vessels in your skin. This occurs when neutrophils (a type of immune cell) enter the walls of small blood vessels where they disintegrate, leaving behind fragments. It may be triggered by a variety of different factors; however, approximately half of the cases are idiopathic (i.e. have unknown cause). Some triggers include infections, certain drugs, collagen vascular disease, autoimmune disease, or neoplastic disease. Drugs and infections are the most common triggers. Symptoms of the skin usually develop about a week after the triggering event. Approximately 90% of patients will have spontaneous healing of skin lesions within weeks to months, and about 10% will have chronic or recurrent disease. Henoch-Schonlein purpura is a subtype of leukoclastic vasculitis that affects children and is usually triggered by an upper respiratory infection.

    Data Source: Graphs on this page represent data in electronic health records and self-reported survey results from the All of Us research database. As of July 2024, there are 451,000 sets of electronic health records and over 560,000 participants who have completed initial survey questions. This dataset, however, may not be representative of the US population. A snapshot of the data can be found here. To protect participant anonymity, results derived from fewer than 20 participants are not graphed.

    Data Source: Graphs on this page represent data in electronic health records from the All of Us research database. As of July 2024, there are 451,000 sets of electronic health records collected from participants. In the United States, because electronic health records use billing codes for diagnoses, some conditions may not be perfectly captured by these data, especially if the condition is rare. A snapshot of the data can be found here. To protect participant anonymity, results derived from fewer than 20 participants are not graphed.
