title: Clinical and morphological recovery between two episodes of acute glomerulonephritis: a light and electron microscopic study with immunofluorescence.
abstract: A 4 year-old girl presented with 2 episodes of acute glomerulonephritis with clinical and morphological recovery between them. Both episodes were preceded by impetigo. The first and third renal biopsies showed glomerulitis with diffuse dense deposits in the mesangium, segmentary intramembranous dense deposits, atypical "humps" and granular C3. The second biopsy, taken between episodes, was considered to be normal. Two years and 5 months after the second episode the clinical evaluation and laboratory tests were normal.
