title: Evolution of IgA nephropathy into Henoch-Schoenlein purpura in an adult.
abstract: IgA nephropathy (IgAN) and Henoch-Schoenlein purpura (HSP) are clinically distinct conditions indistinguishable on renal biopsy. However, progression from IgAN to HSP has rarely been reported, particularly in adults. We report such a case: a young man with biopsy-proven IgAN and no systemic features of HSP who six years later developed classical HSP. This supports suggestions that the two conditions are different manifestations of the same disease.
