Figure 1 Abdominal computed tomography scan and histology of the mass. A: Computed tomography of the abdomen reveals a large mass, highlighted in red, in the left lobe; B: Effacement of normal liver by nodules of atypical lymphocytes [hematoxylin-eosin (H and E), 2.5 ×]; C: Hepatocytes are admixed with neoplastic lymphocytes (H and E, 20 ×); D: Lymphoma cells infiltrate into the bile duct forming lymphoepithelial lesions (arrows) (H and E, 40 ×); E, F: By immunohistochemistry, the neoplastic cells are positive for CD20 (E) and negative for CD5 (F) (40 ×, each).

Figure 2 Positron emission tomography-computed tomography and histology of the liver mass. A: Liver shows diffuse fluorodeoxyglucose activity throughout the parenchyma with the maximum standardized uptake value of 8.6; B: The atypical lymphocytes grow diffusely forming mass with occasional lymphoepithelial lesions (40 ×); C, D: By immunohistochemistry, the neoplastic lymphocytes are positive for CD20 (C, 40 ×) and have low MIB-1 proliferative index (D, 40 ×).
