Fig. 2

Immunohistochemical and molecular findings. A Faint CD68 expression in neoplastic cells (CD68 immunostain; original magnification: 600x). B Faint CD31 expression in neoplastic cells (CD31 immunostain; original magnification: 600x). C Epstein-Barr virus-encoded RNA is detected in neoplastic cells (EBV chromogenic in situ hybridization; original magnification: 200x). D IgG-positive plasma cells in large fibrotic areas (IgG immunostain; original magnification 200x). Shown as inset: approximately 25% of IgG-positive plasma cells are IgG4-positive (IgG4 immunostain; original magnification: 200x)
