In PASM staining, 60 % of tubules were atrophic, others showed dilatation with flat epithelial cells, renal interstitial showed diffuse fibrosis with a large number of plasma cell diffuse infiltration and IgG4 staining was positive (average 47 IgG4-positive plasma cells per high power field) (Figs. 1, 23).
