Renal biopsy data for Case 3: (A–C) First renal biopsy demonstrating (A); light microscopy with Jones silver stain demonstrating membranoproliferative pattern of injury 40×; (B) immunofluorescence demonstrating dominant C3 binding in a segmental confluent granular to pseudolinear pattern; (C) electron microscopy showing dense deposits within segments of the basement membrane, it also shows electron dense deposit-like aggregates in scattered subepithelial and intramembranous areas; (D–F) second renal biopsy re-demonstrates a membranoproliferative pattern of injury, C3 dominant binding on immunofluorescence and dense deposits.
