In light microscopy, a focal proliferative glomerulonephritis with mesangial segmental hypercellularity and increase in the mesangial matrix was seen in almost all glomeruli. Immunofluorescense microscopy demonstrated mesangial, granular IgA depositions and lesser amounts of C3 and kappa (Figure 1).
