Fig. 3. Pathologic findings of Epstein-Barr virus (EBV)-associated posttransplant lymphoproliferative disorder, characterized by T cell lineage of the liver. (A-C) Hematoxylin and eosin staining demonstrates infiltration of small lymphoid cells within the sinusoids, accompanied by occasional lobular necroinflammatory activity. The lymphoid cells were positive for (D) CD3, (F) Ki67, and (G) CD56 and negative for (E) CD20. (H, I) EBV in situ hybridization yielded positive results in scattered small T lymphocytes. The scale bar represents 100 μm. (A, B, D–H) ×200, (C, I) ×400 magnification.
