Light microscopy findings (PAS stain; PAM stain, 400x). Light microscopy Olympus BX53, OLYMPUS DP73 camera, and cellSense (Olympus Corporation, Center Valley, PA, USA) was used to capture the images. The images were obtained with eyepiece at 10X magnification and objective at 40X. No enhancement of the images was performed. The measured resolution was 4800 × 3600. The histological pattern was predominantly membranoproliferative glomerulonephritis characterized by diffuse and global double-contoured glomerular capillary walls (red arrow) with mesangial cell interposition and mesangial expansion by increased mesangial cell number and matrix. Moreover, it showed endocapillary hypercellularity (black arrow)
