title: Henoch-Schönlein purpura presenting with anuria in an adult.
abstract: Henoch-Schönlein purpura (HSP) is an immune complex-mediated systemic small vessel vasculitis that is most commonly described in children but may affect patients of any age. Our patient, a 91-year-old man, presented with anuria caused by IgA-mediated nephropathy; he later developed cutaneous leukocytoclastic vasculitis, thereby meeting the criteria for a diagnosis of HSP. This case is unique because of the patient's initial presentation with anuria, the possible underlying malignancy associated with his HSP, and his advanced age.
