Leukocytoclastic vasculitis, hepatitis B, and the risk of endoscopy

Leukocytoclastic vasculitis, presenting with palpable purpura, is a relatively common problem encountered by both primary care practitioners and dermatologists. A variety of potential etiologies exists and includes autoimmune, neoplastic, and infectious causes. We report a case of leukocytoclastic vasculitis that led to the diagnosis of acute hepatitis B, perhaps acquired through colonoscopy.
