FIGURE 2

Anti-LRP2 nephropathy with concurrent kidney infiltration by CLL/small lymphocytic lymphoma (SLL) (Case 2). (A) Wedge-shaped TBM immune deposit (Jones, ×400). (B) Widespread TBM. (C) Focal brush border staining for IgG. (D) Immune deposits embedded within TBM and bulging toward the luminal aspect (transmission electron microscopy, direct magnification ×590). (E) TBM immune deposits stained with LRP2 (image courtesy of Dr Nidia Messias, Arkana Labs). (F) Capsular and patchy interstitial infiltrate (periodic acid–Schiff, ×100) is composed of (G) CD20-positive B cells (×200) with (H) a kappa light chain restriction by in situ hybridization studies (×200); lambda light chain in situ hybridization is negative (inset, ×200), consistent with a monoclonal B-cell population.
