Acute poststreptococcal glomerulonephritis mimicking Henoch-Schönlein purpura.

Two children with acute glomerulonephritis, cutaneous vasculitis, and abdominal pain are reported. One child also had transient arthralgia and gastrointestinal hemorrhage. Although the clinical presentation mimicked many of the features of Henoch-Schönlein purpura, both patients had unusual variants of poststreptococcal glomerulonephritis.
