HCV-seropositive primary hepatic DLBCL. a, b, c Immunoperoxidase staining. d In situ hybridization, ×200. a Many CD20-positive large lymphoid cells show a diffuse infiltrating pattern. b CD10-positive large lymphoid cells are diffusely distributed. Bile canaliculi have focal weak CD10-positivity in the upper right hepatic lobule. c Large lymphoid cells are positive for CD25. d Many nuclear EBER signals are detected in medium-sized and large lymphoid cells. Two bile ducts on the right are preserved
