Forty-four cases of Hodgkin's disease (HD), mostly of the nodular sclerosing type, were investigated for the presence of Epstein-Barr virus (EBV) by polymerase chain reaction (PCR) and DNA and RNA in situ hybridization (DISH, RISH), as well as by immunohistochemistry for the detection of latent membrane protein-1 (LMP-1) of EBV. In situ hybridization (ISH) was combined with immunohistochemistry to correlate the presence and activity of the virus at the cellular level. In 18/34 (53 per cent) cases, EBV-DNA sequences could be detected with the PCR method. In 12/18 positive cases, DISH and RISH were also positive. In the remaining six EBV-PCR positive cases, two were also positive with RISH and LMP-1, whereas no positive signal with DISH could be obtained. All DISH and/or RISH positive cases were also positive for LMP-1. With RISH, not only the Reed-Sternberg cells and their mononuclear variants (RS cells) stained positive, but also small and intermediate cells frequently reacted with the EBV-specific probes (EBER-1 and -2). Double staining with cellular markers (CD3, CD20, CD45, CD45RO, CD68, and the lectin PNA) revealed that most of the smaller EBER-positive cells frequently did not express T, B, or histiocytic markers, but that they, as well as the RS cells, showed cytoplasmic and membranous staining with PNA. These smaller EBER-positive cells were not found in EBV-PCR negative HD. EBER-positive RS cells were almost always LMP-1 positive, as well as a substantial proportion of the intermediate-sized cells, whereas the majority of the small EBER-positive cells remained LMP-1 negative.(ABSTRACT TRUNCATED AT 250 WORDS)

Epstein-Barr virus (EBV) recently has been implicated in the pathogenesis of Hodgkin's disease (HD). Lymphomatoid papulosis (LyP) is a premalignant cutaneous lymphoproliferative disorder which shares several characteristics with HD. The hypothesis has been made that EBV may be associated with the pathogenesis of LyP. We therefore examined 17 skin biopsy specimens and two lymph nodes from nine patients with LyP for EBV RNA using the highly sensitive and specific EBER method. In all specimens, the large atypical cells were negative for EBV while poly T studies confirmed the presence of adequate RNA for detection of EBER. The negative EBER results were confirmed in seven LyP patients whose biopsies were also stained for latent membrane protein (LMP-1). Interestingly, one patient with clonally related LyP and HD had no EBV RNA detected in any specimen. We conclude that EBV is unlikely to be an important aetiological agent in LyP. If confirmed in other patients, HD associated with LyP may have a different aetiology from HD arising de novo.

CD30+ anaplastic large cell lymphoma (ALCL) represents a novel lymphoma entity at the borderline between Hodgkin's disease and non-Hodgkin's lymphomas. Phenotypic, genotypic, and karyotypic analyses have shown that ALCL are heterogeneous in cellular origin, and may be conceived as malignancies derived from activated, mainly T- or B-lymphoid cells, in some instances with an immature genotype. Epstein-Barr virus genomes and gene products, most notably the transformation-associated latent membrane protein (LMP), have been detected in a proportion of cases, and some cutaneous ALCL proved to harbor complete or incomplete HTLV-1 proviruses. These findings suggest that both EBV and HTLV-I, which are powerful inducers of CD30 expression in lymphoid cells in vitro, may contribute to the pathoetiology of ALCL.

Recently, in situ hybridization (ISH) techniques have shown that Epstein-Barr virus (EBV) could be detected in tumor cells of most angiocentric T-cell non-Hodgkin's lymphomas (NHL). These studies included only a few cases of T-NHL of the lung and pulmonary B-NHL and have not been investigated. Furthermore, the expression of the EBV-encoded latent membrane protein (LMP), which is known for its oncogenic properties, has not been reported. Twelve pulmonary NHL (six angiocentric T-NHL and six B-NHL) arising in nonimmunocompromised patients were examined for the presence of EBV-EBER mRNAs and LMP with ISH and immunohistochemistry, respectively. Four cases of pulmonary lymphomas arising in immunocompromised patients were also included in the study for comparison (one T-NHL in a patient under immunosuppressive treatment and three B-NHL in AIDS patients). EBV-RNA and LMP were detected in tumor cells in two of six nonimmunocompromised angiocentric T-NHL and in the four immunocompromised NHL. The six nonimmunocompromised B-NHL were EBV negative. These results suggest that EBV is associated with some angiocentric pulmonary T-NHL arising in patients without overt immunodeficiency whereas it is absent in such patients with B-NHL. The presence of the transforming EBV-encoded LMP in tumor cells suggests that EBV may be involved in the pathogenesis of some pulmonary T-NHL.

Epstein-Barr virus (EBV) can be detected in Hodgkin and Reed-Sternberg (HRS) cells in about one-half of cases of Hodgkin's disease (HD) in Western countries. To determine whether EBV is also associated with HD in a developing country such as China, we studied paraffin sections from 28 Chinese cases of HD for expression of latent membrane protein-I (LMP-I) and EBV-encoded small RNA (EBER-I), using immuno-histology and RNA/RNA in situ hybridization respectively. The cases were selected from a large series of Chinese lymphomas following histological and immunophenotypical revision. EBV gene expression was found in HRS cells in 17/28 cases, and was related to histological sub-type, being present in 10/11 of mixed cellularity, 6/14 nodular sclerosis, 0/1 lymphocytic predominance, 0/1 lymphocytic depletion, and 1/1 unclassified HD. The 2 methods for detecting EBV gene expression gave similar results, except in one case of nodular sclerosis, in which HRS cells were negative for EBER-I, but weakly positive for LMP-I. In 5/12 cases with EBER-negative HRS cells, rare small or medium-sized lymphocytes expressed EBER-I but not LMP-I. These results suggest that (i) Chinese HD is frequently associated with EBV; (ii) the proportional frequency and sub-type distribution of EBV-positive HD are similar in China and in the West; (iii) both LMP-I immunohistology and EBER in situ hybridization reliably detect EBV in HRS cells in routine biopsies, but the former is simpler and less resource-consuming to perform.

By in situ hybridization with EBER oligonucleotides and immunohistochemistry with anti-latent membrane protein 1 (LMP1) antibody, we compared the detection rate of Epstein-Barr virus (EBV) in Hodgkin's disease and anaplastic large-cell lymphomas in children. Among the 13 cases of Hodgkin's disease tested, 7 (54%) were found to be EBV associated (EBER transcripts +, LMP1 +). None of the 11 cases of ALC lymphomas was found to contain EBV genomes or gene products. This may indicate that EBV is not a pathogenic agent in anaplastic large-cell lymphomas in children in comparison to Hodgkin's disease.

Molecular analysis of the LMP (latent membrane protein) oncogene was performed in 21 Epstein-Barr virus (EBV) positive cases of Hodgkin's disease (HD) with proven LMP gene expression. In each case, viral DNA of the LMP gene was assessed for polymorphism (deletions, insertions, mutations) by polymerase chain reaction (PCR) amplification with selected primers. Specificity of the amplified targets was proven by internal oligonucleotide hybridisation and nested primer PCR. Homogeneity of the 5' LMP gene region coding for the amino terminal, transmembrane, and short extracytoplasmic domains of the protein was identified in all cases. However, deletions or insertions of small DNA sequences within the coding region for the intracytoplasmic LMP domain were observed in about 20% of cases. In one of them, a 30-base-pair deletion was precisely localized by DNA sequencing. A particularly high frequency of DNA polymorphism (30% of cases) was found in the 3' untranslated LMP region. However, when analysing the LMP gene in seven benign conditions, no DNA polymorphism was found. These data suggest conservation of oncogenic LMP regions coding for the protein domains known to be associated with transforming capacities and immunogenic functions. They also show a considerable genomic heterogeneity of the coding region for the intracytoplasmic domain and the 3' untranslated mRNA region. This LMP DNA polymorphism identified within a localized (Swiss) population suffering from HD is unexpected. Its eventual clinical significance remains to be determined.

Recent literature suggests that usual Hodgkin's disease (nodular sclerosing and mixed cellularity types or UHD) and nodular lymphocyte predominance Hodgkin's disease (NLPHD) may be distinct clinical and pathologic entities. Thus, coexistence of NLPHD and UHD in the same patient is expected to be rare. We undertook a review of cases accessioned as NLPHD and UHD in the Laboratory of Surgical Pathology at Stanford University Hospital between January 1980 and May 1992 and found five patients with UHD that predated, followed, or coexisted with lesions histologically typical of NLPHD. All of the patients were male with ages ranging from 10 to 30 years at presentation (median, 22 years; mean, 22.2 years). The sites initially involved by disease were primarily peripheral lymph nodes in the region of the head and neck: cervical (three), supraclavicular (one), submandibular (one). One patient presented with mixed-cellularity Hodgkin's disease (MCHD), two with nodular sclerosis Hodgkin's disease including the cellular phase, one with NLPHD, and the remaining patient presented with a composite malignancy comprising MCHD and NLPHD. Development of the second lymphoma was associated with a somewhat more variable distribution of nodal involvement. The morphologic features in each biopsy specimen resembled either typical NLPHD or UHD, except for one case in which cells with features of both Reed-Sternberg cells and lymphocytic and histiocytes cells were identified. However, the immunophenotypic profiles obtained with a panel of monoclonal antibodies remained distinct for all cases studied. None of the cases showed reactivity with antibodies against the Epstein-Barr-virus latent membrane protein. Thus, NLPHD and UHD maintain a distinct phenotype, even when occurring in the same patient. A second conclusion is that the utility of Leu-7 (CD57) reactivity in distinguishing NLPHD applies to problematic as well as classic cases. Finally, Epstein-Barr virus is not implicated in NLPHD cases associated with UHD.

Epstein-Barr virus (EBV) has been demonstrated in association with Hodgkin's disease (HD) in approximately 40 to 50% of cases in series from North America, Europe, and Japan. However, few data are available concerning this association in developing countries. Recent studies, including mostly a pediatric population from Peru and a pediatric population from Honduras, showed a higher percentage of EBV positivity compared with those in developed countries. To determine the prevalence of EBV in Hodgkin's disease in a Mexican adult population, we analyzed 50 formalin-fixed, paraffin-embedded cases of HD by a three-step technique using a monoclonal antibody to the latent membrane protein of EBV. All the cases were confirmed immunophenotypically as HD (CD15+ and/or CD30+, CD45-). Reed-Sternberg cells and variants were positive for LMP in 35 cases (70%). The staining was found both on the cell surface and/or within the cytoplasm with enhancement of the Golgi area. EBV latent membrane protein was found in 1/1 case (100%) of diffuse lymphocyte-predominant HD, 10/20 cases (50%) of nodular-sclerosis, 18/22 cases of mixed-cellularity (81%), and 6/7 (86%) cases of lymphocyte-depleted HD. Our results show a high prevalence of EBV in HD in this Mexican adult population. All histologic subtypes of HD in the population analyzed appear to be strongly associated with EBV, in contrast to the strong association of mixed cellularity HD in developed countries. Patient age and gender were not predictive of the presence of EBV.

We report a patient from an endemic area of adult T-cell leukemia/lymphoma (ATLL), who developed lymphoma with features characteristic of Hodgkin's disease (HD). Large atypical Reed-Sternberg/Hodgkin's cells (RS/H cells) had a CD3-CD15+CD20-CD30+CD45RO- immunophenotype. Epstein-Barr virus (EBV) latent membrane protein and EBV-encoded small RNA were detected in the RS/H cells. The patient received C-MOPP/ABVD chemotherapy for the HD resulting in a partial response. However, relapse occurred and he died of disease progression associated with serious bacterial infection. Although serial lymph node biopsies revealed consistent presence of the EBV-positive RS/H cells, the background small lymphocytes showed progressive increase in pleomorphism and nuclear irregularity. The lymphocytes had the T-cell phenotype, CD3+CD4+CD7-CD8-. Southern blot analysis using DNA probes for the human T-cell lymphotrophic virus-I (HTLV-I) and the T-cell receptor beta-chain gene demonstrated expansion of the HTLV-I infected monoclonal T-cells with the disease progression. We concluded that the patient synchronously presented two independent lymphoproliferative disorders; EBV-associated HD and ATLL resulting from HTLV-I infection.
