case_images: Light microscopic (a-c) and electron microscopic (d) findings of kidney biopsy. a, b A mild infiltration of inflammatory cells, chiefly composed of lymphocytes and plasma cells was observed along with a small number of eosinophils in the interstitium of the kidney cortex (hematoxylin-eosin stain). c Fibrosis in the tubulointerstitium was mild (Masson trichrome stain). d Electron microscopy showed no deposits, no thickening or thinning of the basement membrane, and little foot process effacement in the glomerulus
