We describe a 70-year-old woman with B-cell chronic lymphocytic leukaemia without nodal involvement, who developed non-Hodgkin malignant lymphoma in the toe-nails. Clinically, the affected nails looked like a typical mycotic infection, but later small tumours developed which affected the nails, and biopsy established the diagnosis. Treatment with chlorambucil (Leukeran) and prednisolone had a striking effect. Malignant infiltration of B lymphocytes in the nails is very rare, but should be considered in patients with malignant haematologic disease.

While Hodgkin's disease (HD) and non-Hodgkin's lymphoma (NHL) have long been regarded as distinct disease entities, recent observations suggest a closer association. The analysis of cases in which these diagnoses are made in the same anatomic site (composite lymphomas) or in separate sites (simultaneous or sequential HD and NHL) indicates that this phenomenon occurs more frequently than would be expected by chance alone. The most common form of composite lymphoma is coexistent nodular lymphocyte-predominant Hodgkin's disease (NLPHD) and large cell lymphoma (LCL) of B cell phenotype. This finding is consistent with a B cell origin for the abnormal cells in NLPHD, suggesting that LCL represents a form of histologic progression, with the existence of a clonal relationship between the two components. The association of other forms of HD (nodular sclerosis or mixed-cellularity) and NHL is less common, but still significant. As with NLPHD and LCL, one may observe composite lymphomas, or the diagnosis of HD may precede or follow the diagnosis of NHL. The vast majority of NHLs associated with HD are of B cell origin, most commonly follicular lymphomas. An association between HD and B cell chronic lymphocytic leukemia (CLL) is also observed. In selected cases, Reed-Sternberg (RS) cells are seen in a background of otherwise typical CLL, and some of these patients have progressed to disseminated HD. These findings suggest that, at least in some cases, HD may be clonally related to an underlying B cell malignancy, and that the RS cell may be an altered B lymphocyte.(ABSTRACT TRUNCATED AT 250 WORDS)

The final Workshop of the meeting focused on cases of Hodgkin's disease (HD) in combination with non-Hodgkin's lymphoma (NHL), either T, B, or anaplastic large cell (ALC) type. The cases selected for this session fell into five categories: nodular lymphocyte-predominance Hodgkin's disease (NLPHD) with NHL, B cell chronic lymphocytic leukemia (CLL) with HD-like transformation, follicular lymphoma (FL) with HD or anaplastic large cell lymphoma (ALCL) (composite or discordant), HD following mycosis fungoides (MF), and HD following ALCL. Taken together, these cases left the participants with the distinct impression that there is likely to be some biological relationship between HD and a variety of T cell and B cell NHL.

B-cell associated antigens are frequently expressed by the Reed-Sternberg (RS) cells of lymphocyte predominance (LP) Hodgkin's disease (HD) and are sometimes expressed by those of nodular sclerosis (NS) and mixed cellularity (MC) HD. Clonal immunoglobulin gene rearrangements have been detected in some HD cases as well. These findings suggest that at least some cases of HD may be of B-cell derivation. Rearrangements of the bcl-2 gene, associated with the t(14;18)(q32;q21) are present in more than 75% of follicular and 30% of diffuse lymphomas of B-cell origin, suggesting that this translocation plays an important role in B-cell lymphomagenesis. In this study, we investigated 34 cases of HD (10 LP, 14 NS, and 10 MC) for bcl-2 gene rearrangements to determine if this B-cell lymphoma-associated translocation also plays a role in the pathogenesis of HD. The cases of HD were analyzed by Southern blot hybridization, using DNA probes that detect the major and minor breakpoint cluster regions and a 5'bcl-2 breakpoint region recently cloned and found to be involved in B-cell chronic lymphocytic leukemia, and by the polymerase chain reaction (PCR), using oligonucleotides capable of amplifying and detecting the major breakpoint region (mbr) and minor cluster region (mcr) breakpoint regions in t(14;18). bcl-2 translocations were not detected in any of the 34 cases of HD by Southern blot hybridization or by PCR. This is in spite of the fact that RS cells expressing B-cell-associated antigen CD20 were detectable in 7/8 cases of LP HD and 6/24 cases of NS and MC HD with monoclonal antibody L26. Therefore, these results indicate that the bcl-2 gene translocation does not play an important role in the pathogenesis of HD and did not provide evidence for the B-cell origin of HD.

The association of chronic lymphocytic leukemia (CLL) and Hodgkin's disease has been controversial. Pleomorphic lymphoreticular cells resembling Reed-Sternberg cells have been observed in Richter's syndrome. Although most observers have favored the view that these cells are a component of a pleomorphic non-Hodgkin's lymphoma, some cases of histologically typical Hodgkin's disease have been described. We have studied two cases that appear to represent composite CLL and Hodgkin's disease, providing evidence for an interrelationship of these two disorders. Classic Reed-Sternberg cells and variants (RS-H) were seen in a background that was otherwise typical of CLL. Both patients initially presented with characteristic findings of CLL in the peripheral blood and bone marrow. The first patient was found to have RS-H cells within lymph nodes at initial presentation, and ultimately progressed to develop a disseminated lymphoma characteristic of Hodgkin's disease. In the second patient, RS-H cells were not discovered until 5 years later. Immunophenotypic studies confirmed these morphologic impressions. The predominant lymphocyte population had a phenotype consistent with B-cell CLL. By contrast, the RS-H cells were strongly positive for CD15 (Leu M1) with staining of the Golgi region and cell membrane. Additionally, the RS-H cells were surrounded by rosettes of lymphocytes that marked as T cells. In both of the patients, a small percentage of RS-H cells expressed positivity for the B-cell marker L-26, which may indicate an origin from the underlying CLL. These findings support a B-cell origin for the malignant cell in some cases of Hodgkin's disease and suggest that Hodgkin's disease in some patients may be related to or derived from a coexisting lymphoid malignancy.

A study was conducted to evaluate the usefulness of paraffin-immunohistochemistry for histopathological classification of non-Hodgkin's malignant lymphomas (NHML). the phenotypes of lymphoma cells and other cells were examined using 11 monoclonal and 3 polyclonal antibodies by the ABC method on paraffin-embedded tissue sections of 226 cases of NHML, comprising 94 B-cell lymphomas (B-ML) and 132 T-cell lymphomas (T-ML). In 219 NHML cases (96.8%), lymphoma cells reacted with more than one of these antibodies. A set of MB-1, Mx-pan B, L26, LN-1, LN-2 and anti-immunoglobulin light chain antibodies characterized each subtype of B-MLs, categorized according to the Kiel classification. Mantle-zone lymphoma (MzML) was added as one subtype. L26 stained the largest number of B-MLs (82.8%). B-cell chronic lymphocytic leukemia (B-CLL) was labeled most frequently by MB-1. MzML was characterized by reactivity of lymphoma cells with LN-2 and by the appearance of monoclonal immunoglobulin light chain along the cell membrane. Follicle center cell lymphomas were stained by LN-1 and LN-2, although a small number of proliferating cells were labeled by LN-1 in B-CLL, MzML and the immunocytoma lymphoplasmacytic/cytoid variant. MT-1 and/or UCHL-1 showed various degrees of reactivity with the cell membranes of lymphoma cells in 94.8% of T-MLs. Among the T-cell pleomorphic lymphomas of Suchi and Lennert, the adult T-cell leukemia/lymphoma type, defined by stippled heterochromatin distribution and peculiar huge cells, reacted selectively (p less than 0.05) with anti-phosphokinase C antibody. Anaplastic large cell T-ML reacted with a set of Ber H2, LN-2 and Leu M1. In T-zone lymphomas without hyperplastic follicles, angioimmunoblastic lymphadenopathy with dysproteinemia-type T-ML, lymphoepithelioid cell lymphomas and some pleomorphic lymphomas comprising clear large lymphoma cells, there were many intermingling B cells, and their constitution varied. In some lymphoblastic lymphomas of both the T cell and B-cell type, phenotypes of T cells and B cells were expressed. Consequently, it was shown that paraffin immunohistochemistry was useful for the practical histopathological diagnosis of NHML even in the area where human T-cell leukemia virus type 1 is endemic.

We have investigated the frequency of p53 mutations in B- and T-cell human lymphoid malignancies, including acute lymphoblastic leukemia, the major subtypes of non-Hodgkin lymphoma, and chronic lymphocytic leukemia. p53 exons 5-9 were studied by using genomic DNA from 197 primary tumors and 27 cell lines by single-strand conformation polymorphism analysis and by direct sequencing of PCR-amplified fragments. Mutations were found associated with (i) Burkitt lymphoma (9/27 biopsies; 17/27 cell lines) and its leukemic counterpart L3-type B-cell acute lymphoblastic leukemia (5/9), both of which also carry activated c-myc oncogenes, and (ii) B-cell chronic lymphocytic leukemia (6/40) and, in particular, its stage of progression known as Richter's transformation (3/7). Mutations were not found at any significant frequency in other types of non-Hodgkin lymphoma or acute lymphoblastic leukemia. In many cases, only the mutated allele was detectable, implying loss of the normal allele. These results suggest that (i) significant differences in the frequency of p53 mutations are present among subtypes of neoplasms derived from the same tissue; (ii) p53 may play a role in tumor progression in B-cell chronic lymphocytic leukemia; (iii) the presence of both p53 loss/inactivation and c-myc oncogene activation may be important in the pathogenesis of Burkitt lymphoma and its leukemic form L3-type B-cell acute lymphoblastic leukemia.

In diagnostic pathomorphology of lymphoproliferative diseases, immunohistochemical methods are of great importance. These methods help to elucidate the following issues: reactive or malignant nature of a lesion, origin of atypical cells (lymphoreticular or other), type of malignant lymphoma (Hodgkin's disease or malignant non-Hodgkin lymphoma, NHL), grade of malignancy, T- or B-cell origin and subtype of NHLs. All results of immunohistochemistry should be carefully scrutinized in the light of routine pathomorphological findings. The possibilities of immunohistochemistry are demonstrated by two examples: 1. Origin and stage of differentiation of B-cell chronic lymphocytic leukaemia cells with special emphasis on the presence of follicular dendritic reticulum cells in the lymph nodes of a few, otherwise typical cases of CLL. 2. Description of two cases of a new type of NHL that contains intrasinusoidal B-cells. Monoclonal plasma cells with immunoglobulins of the same isotypes as those of intrasinusoidal B-cells were observed in both cases. These findings suggest that the intrasinusoidal B-cells may be plasma cell precursors.

Using a probe for the newly described bcl-3 gene near the breakpoint of the t(14;19), 176 cases of non-Hodgkin lymphoma and B cell chronic lymphocytic leukemia were analyzed. Rearrangement of the bcl-3 gene was found in only one case; a follicular lymphoma involving the salivary gland that had progressed to a diffuse large cell lymphoma. We conclude that rearrangement of the bcl-3 gene as detected by our method occurs rarely in mature B or T cell neoplasms.

Oestrogen receptors (ER) are present in neoplastic lymphoid cells and have been considered a physiological marker of growth rate or differentiation. Tamoxifen, an oestrogen antagonist, has been given in some patients with CLL and Hodgkin's disease, with dramatic response in single cases. Until now, ER status has been assessed using a steroid binding assay (SBA) which has many inherent problems. Recently, the development of monoclonal antibodies directed against ER has been applied to the study of breast carcinomas and results obtained show good correlation with the quantitative SBA. We studied 49 cases of B-cell chronic lymphocytic leukemia (CLL) using immunostaining of cytospin preparations. In 30 of these cases ER enzyme immunoassay (ER-EIA) was also performed. Cultured MCF-7 cells, derived from a pleural effusion of a breast cancer patient, known to contain high levels of ER were used as a positive control (40-48% ER positive cells by immunocytochemistry; 200 fmol/mg protein by EIA). All of the CLL cases except two (96%) were negative for ER (less than 1% staining; less than 4 fmol/mg protein). The two positive cases expressed granular ER staining over the nucleus (9.2 and 12.1% positive cells) and were positive by EIA and SBA. It is concluded that (i) patients with CLL rarely express ER and (ii) immunocytochemical staining of cytospin preparations is a valid technique for the measurement of ER. It is of interest that one of the positive cases was diagnosed as CLL with Richter's transformation confirming earlier findings.
