C3 and Kimura disease: Renal abnormalities are seen in 10% to 60% and proteinuria is reported in 15% to 18% of the cases of Kimura disease.[2,18,19] Renal lesions, including membranous nephropathy, mesangial proliferative glomerulonephritis, and minimal change disease, typically appear months or even years after lymph node enlargement or development of subcutaneous nodules.[3,20–22] In adults, membranous nephropathy is predominant and immunofluorescent microscopy mainly shows deposition of IgG and C3 and occasionally IgM and IgA, mostly in the capillary loop and less frequently in the mesangium.
