Primary effusion lymphoma (PEL) or body cavity-based lymphoma (BCBL) is a unique subgroup of B-cell lymphomas that exhibits exclusive or dominant involvement of serous body cavities without a detectable tumor mass. We present a case of a PEL/BCBL that exclusively involved the peritoneal cavity of a 58-year-old immunocompetent male with hepatitis C virus (HCV)-related liver cirrhosis. The lymphoma cells were large, highly atypical and expressed CD19, CD20, CD22, CD10, HLA-DR, and CD45 with kappa light chain restriction. Unlike typical PEL/BCBL, human herpesvirus type 8/Kaposi sarcoma herpes virus (HHV-8/KSHV) genomic sequence was not present in the lymphoma cells and there was no serologic evidence of human immunodeficiency virus (HIV) infection. This is the fourth reported case of HHV-8 negative, HIV negative PEL/BCBL in a patient with associated HCV-related cirrhosis and review of these cases showed some consistent clinicopathological features, i.e. exclusive involvement of the peritoneal cavity and phenotypic expression of B-cell associated antigens in contrast to the generally null phenotype PEL/BCBL. The occurrence of these cases suggests that HCV may play an etiological role in a subcategory of PEL/BCBL not associated with HHV-8.
