Figure 1. Microscopy of immunostaining on first (A, B) and second (C-F) biopsy by immunohistochemistry (A-D) or direct immunofluorescence (E, F): (A) weak granular mesangial staining for IgG; (B) moderate intensity mesangial staining for IgA; (C) absent IgG; (D) weak mesangial IgA staining; (E) weak linear IgG; (F) strong granular mesangial IgA staining. Original magnification (A-F) × 400.
