Case 1 (a-d): (a), (b) diffuse alteration of the glomerular structure with marked endocapillary inflammatory hypercellularity, double contours, and crescent formation. Silver stain. (c) Immunofluorescence C3 (+++) with granular pattern and mesangial and capillary distribution. (d) Immunofluorescence IgG (+++) with granular pattern and mesangial and capillary distribution. Case 2 (e-h): (e) glomerulus with marked endocapillary inflammatory hypercellularity. PAS stain. (f) Immunofluorescence IgA (+++) with granular pattern. (g) Immunofluorescence C3 (++) with granular pattern and mesangial and capillary distribution. (h) Immunofluorescence IgG (-).
