Parallel tubular structures (PTS) and/or the associated electron-dense granules, thought to contain molecules responsible for target cell lysis, can be detected in the cytoplasm of lymphocytes with large granular lymphocyte (LGL) morphology. In the present study we compared PTS presence in freshly isolated peripheral blood lymphocytes and peripheral blood lymphocytes incubated overnight in the presence of human pooled serum, sera from patients with Hodgkin's disease and interferon-alpha. Under all conditions we found PTS in the majority of CD16+ cells (64.3-74.8%) but less than 41.8% in CD57+ cells. In the case of double-labeled lymphocytes, 41.0-61.7% CD16+/8+ but only 24.2-27.5% CD57+/8+ cells were PTS+. Thus, in all cases where lymphocytes expressed CD16 antigen there was a high percentage of PTS positivity. Although the PTS+ cells exhibited phenotypic heterogeneity there was, except for a proportion of CD57+ lymphocytes which exhibited less of the characteristic LGL features, generally LGL morphological homogeneity. CD16 lymphocytes are potentially more cytotoxic than CD57 and CD8 cells. Taking this into consideration, the presence of the PTS in the majority of CD16 cells suggests an important role for PTS in target cell lysis.

Two markers for cells in the growth fraction, the T9 antigen (i.e. the transferrin receptor) and the T10 antigen were investigated in frozen tissue sections of 105 non-Hodgkin lymphomas (NHL). The results were correlated with the histological subtype and the pattern of tumour infiltration by reactive cells. Special attention was directed to the density of natural killer (NK)-like cells using the anti-HNK1 (Leu7) antibody since the transferrin receptor (tfr) or other growth-associated membrane structures may serve as target for NK cells. Our study confirms a relationship between number of tumour cells with the T9 marker and tissue infiltration by HNK1+ cells in NHL of low (chronic lymphocytic leukaemia, hairy-cell leukaemia, immunocytic lymphoma, centroblastic-centrocytic lymphoma) and intermediate (centrocytic and centroblastic lymphoma) but not in NHL of high malignant grade (immunoblastic and lymphoblastic lymphoma). Comparable results were obtained with the T10 antigen although the correlation was less close. The percentage of cells in the growth fraction, defined by the expression of the T9 and T10 marker, corresponded with prognostically unfavourable subgroups with the remarkable exception of follicular NHL of centroblastic-centrocytic type. This lymphoma showed high numbers of cells with the T9 and the T10 marker in a microenvironment resembling normal germinal centres in many aspects.

The number of B lymphocytes, T lymphocytes and their helper/inducer, cytotoxic/suppressor and NK/K subpopulations was measured in peripheral blood and spleen cell suspensions from patients with Hodgkin's disease (HD) in the active stage of the disease and in remission status, as well as in Non-Hodgkin lymphomas (NHL) in active stage of the disease. B lymphocytes were determined by direct immunofluorescence and T lymphocytes with the E rosette technique. Helper/inducer, cytotoxic/suppressor, and NK/K T lymphocytes were determined by indirect immunofluorescence with the monoclonal antibodies OKT4, OKT8 and Leu 7 (HNK1). In the same way, Lyt3 was used for determination of the total T lymphocytes. Whereas in peripheral blood of the NHL group an increase of B lymphocytes and a slight reduction of T lymphocytes could be observed, with normal distribution of the subpopulations, in patients with active HD as well as in those in remission, a marked absolute and relative decrease of T helper/inducer cells was found with normal cytotoxic/suppressor and NK/K proportion. In contrast to this, a significant increase of helper/inducer T lymphocytes with decreased cytotoxic/suppressor T proportion was found in spleen cell suspensions of patients with HD.

Several recent reports have suggested that nodular lymphocyte predominance Hodgkin's disease (NLPHD) may be distinct from other forms of Hodgkin's disease and may be more closely related to B-cell non-Hodgkin's lymphoma. This is primarily based on immunophenotypic studies that have shown that the L & H cells in NLPHD demonstrate a B-cell phenotype. In 1989, Poppema reported that the T cells in NLPHD differ from T cells in other forms of Hodgkin's disease in that they demonstrate reactivity for Leu 7 (CD57). In this study we tested the hypothesis that Leu 7 (CD57) reactivity of small lymphocytes in NLPHD is an immunophenotypic feature that distinguishes NLPHD from nodular sclerosing Hodgkin's disease and from certain B-cell lymphomas that may histologically simulate NLPHD, namely T-cell-rich B-cell lymphoma and follicular lymphoma. Using an image analysis method, we found Leu 7 (CD57) reactivity in an average of 18.9% of the small lymphocytes in the nodules of NLPHD compared with 3.9% in nodular sclerosing Hodgkin's disease, 4.3% in T-cell-rich B-cell lymphoma, and 2.1% in follicular lymphoma. Moreover, Leu 7 (CD57)-reactive small lymphocytes often showed a distinctive pattern in NLPHD, forming a ring of cells around the large L & H cells. While scattered Leu 7 (CD57)-reactive lymphocytes were found in the other disorders, the percentage of reactive cells and the pattern of reactivity were significantly different in NLPHD. These results suggest that Leu 7 (CD57) reactivity may be used as an additional immunophenotypic criterion in distinguishing NLPHD from nodular sclerosing Hodgkin's disease, T-cell-rich B-cell lymphoma, and follicular lymphoma. The clinical and biological significance of Leu 7 (CD57) reactivity of small lymphocytes in NLPHD merits further investigation.

Epstein-Barr virus (EBV) has been associated with a wide variety of neoplastic conditions including nasopharyngeal carcinoma, gastric carcinoma, lymphoproliferative disorders in immunocompromised hosts, Hodgkin's disease, and non-Hodgkin's lymphomas of either B or T-cell phenotype. Although the presence of EBV in neoplastic lymph nodes has been well studied, very few studies have examined the distribution of EBV in normal or reactive lymph nodes. We studied normal or reactive lymph nodes from patients in Peru, a geographical region with a relatively high prevalence of EBV infection as compared with the United States or Europe. EBV DNA-RNA in situ hybridization was performed using a 30-base biotinylated oligonucleotide complementary to the EBER1 gene of EBV. Ten cases showed the presence of EBV RNA in scattered cells (less than 50 per section) and were utilized in the study. Most of the cells labeling for EBV RNA were small lymphocytes although some large lymphocytes also labeled. These cases were then subjected to double-labeling immunohistochemical/in situ hybridization studies using monoclonal antibodies L26(CD20), Leu22(CD43), Leu7(CD57), and the polyclonal antibody CD3. In their respective sections, of those cells that showed positive labeling for EBV RNA, 44% double labeled for L26, 24% double labeled for CD3, and 23% double labeled for Leu22. No cells double labeled for Leu7. This study shows that EBV RNA is expressed in both B and T-cells in nonneoplastic lymph nodes. These findings are compatible with other studies that have shown the presence of EBV in both B and T-cell non-Hodgkin's lymphomas.

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.

Possible associations between the immunophenotype of Hodgkin (H) and Sternberg-Reed (S-R) cells, the expression of CD57 (Leu 7) antigen, and the presence of Epstein-Barr virus (EBV) were investigated in lymph node specimens from 50 cases of Hodgkin's disease (HD), including 26 cases of mixed cellularity and 24 cases of nodular sclerosis. Tissues were fixed in 10% neutral formalin, or/and B5 solution. H and S-R cells were CD30+, CD15+ (85% of the cases) and LCA (CD45). A proportion of neoplastic cells positive for either T-cell markers (CD3) or B-cell markers (CD20) was observed in 10% and 34% of the cases, respectively. Membrane positivity for CD57 antigen was found in H and S-R cells in 10 cases (8 cases of mixed cellularity, and 2 cases of nodular sclerosis). Such immunopositivity was only observed in B5-fixed sections. No staining for CD57 antigen was identified in H and S-R cells of any case with CD20 positive neoplastic cells. H and S-R cells of both CD57-positive and CD57-negative cases were further studied by immunohistochemistry for LMP1, by in-situ hybridization for EBER and by polymerase chain reaction (PCR) for EBV-DNA. No association was identified between the expression of CD57 antigen and the presence of EBV sequences, transcripts or proteins. Our findings do not support a B-cell origin for H and S-R cells in CD57-positive cases of Hodgkin's disease and suggest that these neoplastic cells may be related to natural killer (NK) or T-cells expressing CD57 antigen.

B-cell non-Hodgkin's lymphomas with a marked preponderance of reactive T cells, so-called T-cell rich B-cell lymphomas (TCRBCLs), can be morphologically confused with Hodgkin's disease (HD). To establish helpful distinguishing features in paraffin sections, 10 cases of L26-positive, CD15-negative HD and 10 cases of TCRBCL were compared; 4 cases of HD had morphologic features of the nodular lymphocyte predominant (LP) type. Nine of 10 cases of HD contained fewer than 20 mitoses/20 high power fields (hpf) and only 1 had pericapsular involvement. In contrast, 9 of 10 TCRBCL had greater than 20 mitoses/20 hpf and 7 had perinodal infiltration. HDLP was easily distinguished from TCRBCL by the expanded dendritic meshworks outlining the L & H nodules and the high content of CD57-positive lymphocytes. The remaining 6 cases of non-LP L26-positive HD had a relatively distinctive immunostaining pattern, with absence of CD45 and discordant reactivity for L26 and Ki-B5 in Reed-Sternberg cells and variants. Only 3 cases of TCRBCL had a similar CD45 and L26/Ki-B5 immunostaining pattern, and these could be distinguished by demonstrable cytoplasmic light-chain restriction. These results show that evaluation of the mitotic count, pericapsular involvement, and immunohistochemical staining patterns for Ki-M4p, CD57, L26/Ki-B5, and CD45 can help to discriminate TCRBCL from L26-positive HD when only fixed material is available.

Anaplastic large cell lymphoma (ALCL) is composed of large, frequently bizarre, cells of T- or null-cell phenotype that show a preferential sinusoidal growth pattern and consistent CD30 positivity. Whether these tumors represent a single entity or several, and what the exact cell origin, is controversial. Recently, granzyme B, a cytotoxic granule component, was reported in a small percentage of ALCL, suggesting that some cases may originate from cytotoxic lymphocytes. To further investigate this possibility, we performed an immunohistochemical study of 33 ALCLs of T- and null-cell type, using monoclonal antibodies to cytotoxic cell-associated antigens, including CD8, CD56, CD57, and the cytotoxic granular proteins perforin and TIA-1. In addition, CD4 expression was also evaluated. ALCL cases included 27 classical systemic forms and variants, 3 primary cutaneous (PC) forms, and 3 acquired immunodeficiency syndrome-associated forms. Cytotoxic antigen expression was also studied in 51 cases of Hodgkin's disease (HD) and 17 large B-cell lymphomas (LBCLs) with anaplastic cytomorphology and/ or CD30 positivity. We found that 76% of ALCLs, representing all subtypes except the PC forms, expressed either TIA-1, perforin, or both proteins. Expression of TIA-1 and perforin were highly correlated (P < .001). On the basis of their immunophenotypic profiles, several subtypes of cytotoxic antigen positive and negative ALCL could be recognized. Fifty-five percent of ALCLs (18 of 33) displayed an immunophenotypic profile consistent with cytotoxic T cells. Six cases expressed cytotoxic granular proteins in the absence of lineage specific markers, and one case expressed both T-cell- and natural killer cell-like markers. These 7 cases (21%) were placed into a phenotypic category of cytotoxic lymphocytes of unspecified subtype. Twenty-four percent (8 cases) of ALCLs were cytotoxic granule protein negative. All but one of these displayed a T-cell phenotype. Cytotoxic granule protein expression did not correlate with the presence of the NPM-ALK fusion transcript. Only 10% of the 51 HD cases were found to be TIA-1+, and none expressed perforin. Cytotoxic antigen expression was absent in LBCL. The expression of cytotoxic granule proteins in the majority of ALCL implies a cytotoxic lymphocyte phenotype and suggests that most cases originate from lymphocytes with cytotoxic potential. Furthermore, the demonstration of cytotoxic cell related proteins may be a useful addition to the current panel of antibodies used to distinguish ALCL, HD, and anaplastic LBCL.

There is wide consensus that lymphocyte predominance Hodgkin's disease (LPHD) represents a distinct clinicopathological entity of B-cell origin. However, inconsistent results of immunophenotyping studies and low confirmation rates among multi-center trials pose the question of whether LPHD really expresses heterogeneous marker profiles or whether it represents a mixture of morphologically similar entities. Among 2,836 cases reviewed by the German Hodgkin Study Group, immunophenotyping was performed on 1) cases classified or confirmed as LPHD by the reference panel (n = 104) or 2) cases not confirmed as LPHD but classified as classical HD (cHD) within the reference study trial (n = 104). In most cases, immunohistochemistry revealed a phenotype either LPHD-like (CD20+, CD15-, CD30-, CD45+) or cHD-like (CD15+, CD30+, CD20-, CD45-). In 27 cases, the immunophenotype was not fully conclusive. Additional markers for Epstein-Barr virus and CD57 and in situ hybridization for mRNA light chains allowed for a more clear-cut distinction between LPHD and cHD. However, in 25 of 104 cases, immunohistochemistry disproved the morphological diagnosis of LPHD of the panel experts, whereas 13 cases originally not confirmed as LPHD showed a LPHD-like immunopattern. Immunohistochemically confirmed LPHD cases showed a significantly better freedom from treatment failure (P = 0.033) than cHD; this was not observed in the original study classification based only on morphology (P > 0.05). Significantly better survival for LPHD cases improved from P = 0.047 (original study classification) to P = 0.0071 when classified by immunohistochemistry. Our results show that LPHD is a more immunohistochemical rather than a purely morphological diagnosis. Immunophenotyping of HD biopsies suspected of being LPHD is mandatory when a modified therapy protocol, that is, one different from those used in cHD, is discussed.
