Abstract
A 30-year-old white male presented with hematuria, proteinuria and normal renal function following a flu-like illness. IgA was mildly elevated but C3 and C4 levels were normal in serum. Renal biopsy showed a mesangial proliferative nephritis with immunohistochemical features of IgA nephritis but with an unusual pattern and distribution of deposits in glomerular, tubular and Bowman’s capsular basement membranes.
