ABSTRACT
Hepatitis C virus (HCV) infection may be complicated by non-Hodgkin's lymphoma. We describe eight cases of B-cell extranodal non-Hodgkin's lymphoma occurring during the course of chronic HCV-related hepatic disease (low-grade of mucosa-associated lymphoid tissue [MALT]-type; diffuse large cell; Burkitt; diffuse small cell). Some were localized to the liver (2), liver and spleen (1), spleen (1), peritoneal cavity (1), parotid gland (1); others manifested in the nasopharynx (1) and eyelid (1) but were accompanied by nodal disease. Four lymphomatous specimens available for molecular analysis exhibited clonal immunoglobulin gene rearrangements, lacked bcl-2, bcl-6, c-myc genes and p53 alterations, and did not contain replicative intermediate HCV RNA, as documented by a strand-specific reverse transcriptase-polymerase chain reaction. Low levels of positive-strand HCV RNA were detected in a single hepatic lymphoma, suggesting the presence of the virus in residual hepatocytes. The antigen-driven properties of HCV-associated B-cell malignant neoplasms may be considered for hepatic MALT-type lymphoma, which probably originated from lymphoid tissue acquired during long-standing HCV infection.
