(A1-A3) Histological examination of lymph node biopsy: Reactive proliferation of lymphoid tissue in the neck behind the right ear, accompanied by follicular hyperplasia, epithelioid vascular endothelial hyperplasia and a large number of eosinophils infiltration. It's consistent with Kimura's degenerative lymphadenopathy. (B1, B2) Hematoxylin eosin staining showed no eosinophil infiltration in the kidney.

Pathological biopsy in October 2011 suggested: Reactive hyperplasia of lymphoid tissue in the neck behind the right ear, accompanied by follicular hyperplasia, epithelioid vascular endothelial hyperplasia and numerous eosinophilia infiltration, was consistent with KD lymphadenopathy (Figure 1A). Hematoxylin eosin staining showed no eosinophil infiltration in the kidney (Figure 1B).
Mild segmental hyperplasia of mesangial cells and stroma. Vacuolar degeneration of basement membrane. There was mild focal atrophy of the renal tubules, occasional protein, red blood cell tube. Mild small focal fibrosis of interstitium, a small amount of chronic inflammatory cells and foam cell leaching Embellish. The arterioles were thickened. Consider minimal degenerative glomerulopathy.
