Abstract
To better characterize the clonality and pathogenesis of Hodgkin's disease (HD), we used polymerase chain reaction (PCR) and Southern blot to analyze the rearrangement of immunoglobulin (Ig) and T-cell receptor (TCR) genes, the bcl-2 oncogene, and the Epstein-Barr virus (EBV) genotype. In situ hybridization studies of EBV were also done. Twenty-six cases of HD were compared with 15 cases of non-specific lymphadenitis, 7 with incipient adult T-cell leukemia/lymphoma (ATLL), and 4 T-cell rich B-cell lymphomas (TRBL), all of which histologically resembled HD.
