Nuclear expressions for Epstein–Barr virus (EBV) nuclear antigen 2 (EBNA-2) and EBV-encoded RNA 1 (EBER1) were detected with immunohistochemistry (B) and in situ hybridization (C), respectively. The pathological diagnosis was diffuse large B-cell lymphoma with latency type III, EBV-infection.Back to article page
