3 Fig 2 Tissue sections of the pericardium showing (A) massive infiltration of mononuclear cells and plasma cells (H&E, ×100) (inset, H&E, ×200), and (B) IgG4-positive plasma cells (IgG4, ×100) (inset, ×200). (Bars = 50 μm; H&E = hematoxylin and eosin; IgG4 = immunoglobulin G4.)

4 Fig 3 Tissue sections of the mediastinal lymph node showing (A) follicular hyperplasia (H&E, ×20), (B) marked infiltration of plasma cells (H&E, ×100) (inset, H&E, ×200), and (C) IgG4-positive plasma cells. (IgG4, ×100) (inset, ×200) (Bars = 50 μm; H&E = hematoxylin and eosin; IgG4 = immunoglobulin G4.)
