BACKGROUND An etiologically important role has been suggested for hepatitis C virus (HCV) infection in the development of B-cell non-Hodgkin's lymphoma (NHL). HCV has been recognized as the major cause of non-A, non-B chronic hepatitis throughout the world. Moreover, the occurrence of primary splenic malignant lymphoma (PSML) has been demonstrated in patients with chronic liver disease. METHODS In this study, the authors describe three patients with PSML. The clinical, histologic, and immunohistochemical features of the lymphomas were studied. Clonal immunoglobulin heavy chain gene rearrangement was investigated by polymerase chain reaction. RESULTS All three cases of PSML were detected by imaging studies performed in routine follow-up of cases of chronic liver disease associated with HCV infection. Macronodular lesions were found in the three spleens; two of them were of normal weight and another was moderately enlarged. The former two were the smallest PSMLs reported to date. The histology was B-cell NHL in all cases. All 3 patients were alive after splenectomy with an average follow-up of 51.7 months (range, 35-74 months). CONCLUSIONS HCV infection may play an etiologic role in the development of splenic B-cell lymphoma. The long survival of the patients in this study may have been due to early splenectomy.

D016133 Polymerase Chain Reaction In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.

D016403 Lymphoma, Large B-Cell, Diffuse Malignant lymphoma composed of large B lymphoid cells whose nuclear size can exceed normal macrophage nuclei, or more than twice the size of a normal lymphocyte. The pattern is predominantly diffuse. Most of these lymphomas represent the malignant counterpart of B-lymphocytes at midstage in the process of differentiation.
