Abstract
Hepatitis C virus (HCV) is one of the main viral causes of hepatocellular carcinoma (HCC) and is associated with lymphoproliferative disorder such as non-Hodgkin's lymphoma (NHL). However, there are only few case reports on concomitantly induced NHL and HCC by HCV. Herein, we report a case of synchronous NHL and HCC in a patient with chronic hepatitis C which was unexpectedly diagnosed during liver transplantation surgery. This case suggests that although intrahepatic lymph node enlarge-ments are often considered as reactive or metastatic lymphadenopathy in chronic hepatitis C patients with HCC, NHL should also be considered as a differential diagnosis.

Fig. 1.
Gadoxetic acid-enhanced magnetic resonance image shows a 2.3 cm sized hepatic nodule in S8 (white arrows), which is enhanced on arterial phase (A) and washed-out on equilibrium phase (B). Another 2.1 cm sized hepatic nodule in S4 (white arrows) is noted with same enhancement pattern on arterial (C) and equilibrium phase (D). An enlarged lymph node is also seen along the common hepatic artery, and it is enhanced on arterial phase (E) and iso-attenuated on equilibrium phase (F). After the first transarterial chemoembolization, the compact lipiodol uptake by both hepatic nodules is shown in pre-enhanced phase (G, H).

Fig. 2.
(A) Axial and (B) maximum intensity projection image of 18 F-FDG PET-CT shows hyper-metabolic activity in the enlarged periportal lymph node (white arrow), the maximum standar-dized uptake value (SUVmax) of which is 6.8. The SUVmax of the hepatic nodules is 3.45, which is iso-metabolic compared to normal hepatic paren-chyma.

Fig. 3.
Low-power photomicrograph of the periportal lymph node reveals characteristic nodular growth pattern in H&E (A; ×20) and CD20 immunohistochemical stain (B; ×20). At high-power microscopic view, each follicle is comprised predominantly of large cells resembling centroblasts (C; H&E, ×400). The neoplastic lymphocytes are positive for Bcl-6, which is expressed in germinal center cells (D; ×200).
