Chronic lymphocytic leukemia/small lymphocytic lymphoma with Reed-Sternberg-like cells and possible transformation to Hodgkin's disease. Mediation by Epstein-Barr virus.
The pathogenesis of Reed-Sternberg cells and variants (RS-H cells) found in rare cases of chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) is unknown. We studied 13 such cases by immunohistochemistry and in situ hybridization for identification of Epstein-Barr virus (EBV) RNA. The RS-H cells in five cases expressed the B-lineage marker CD20 and were negative for CD15. In two cases, the RS-H cells showed expression of both CD20 and CD15, whereas in another six cases, the cells were positive for CD15 but negative for CD20. Three of the cases expressing CD15 showed subsequent evidence of disseminated Hodgkin's disease. Regardless of the phenotype or clinical behavior, the RS-H cells in 12 of 13 cases were found to contain EBV RNA by in situ hybridization, but the surrounding neoplastic lymphocytes were invariably negative for EBV RNA. It is suggested that EBV has an important role in the pathogenesis of the RS-H cells in these rare cases.

Non-Hodgkin's lymphomas arising in patients successfully treated for Hodgkin's disease. A clinical, histologic, and immunophenotypic study of 14 cases.
We report on 14 patients who developed Hodgkin's disease (HD), were successfully treated, and subsequently developed non-Hodgkin's lymphoma (NHL). The median interval between the diagnosis of HD and the diagnosis of NHL was 136 months (range 11-336). The clinical features of the patients with HD were similar to other patients with HD. Results of biopsies showed 12 nodular sclerosis and one mixed cellularity; one was not further classified. Immunophenotypic studies in nine cases showed that the Reed-Sternberg (RS) and Hodgkin's (H) cells were LeuM1+ LCA-. The patients were treated for HD in a nonuniform manner: two received radiation therapy, four received chemotherapy, and eight received both modalities. The NHLs were usually extranodal (79%) with frequent presentation as an abdominal mass. According to the Working Formulation, six lymphomas were small noncleaved cell (four non-Burkitt's, two Burkitt's), three were diffuse large cell, and two were follicular and diffuse large cell. Three neoplasms were not classified: two lymphomas with plasmacytoid differentiation were placed in the intermediate and low-grade categories, respectively, and one neoplasm was a plasmacytoma. All 14 neoplasms had an immunophenotype typical of NHL of B-cell lineage and were LeuM1-. Seven of the 12 patients treated with combination chemotherapy experienced a complete remission of their NHL. We conclude that the clinical, histologic, and immunophenotypic findings of the NHLs in these patients are analogous to those of NHLs that occur in immunosuppressed patients, suggesting that immunodeficiency plays a role in the pathogenesis of NHLs arising after HD.

Lymphoproliferative lesions in patients with common variable immunodeficiency syndrome.
We reviewed our experience with 30 nodal and extranodal lymphoid lesions from 17 patients with common variable immunodeficiency (CVID). Immunohistochemical studies were performed on biopsies from 15 patients, in situ hybridization for Epstein-Barr virus in nine cases, and gene rearrangement analysis on seven lesions. The biopsies were classified into four groups: malignant lymphoma (two cases); atypical lymphoid hyperplasia (eight cases); reactive lymphoid hyperplasia (14 cases); and chronic granulomatous inflammation (six cases). The two malignant lymphomas were diagnosed using histologic criteria; tissue was not available for the assessment of clonality. In one neoplasm, Epstein-Barr virus was identified in the tumor cells by in situ hybridization. The cases of reactive lymphoid hyperplasia and chronic granulomatous inflammation had no atypical architectural, cytologic, or immunohistochemical features. The cases of atypical lymphoid hyperplasia were of particular interest, as these patients had either widespread involvement or massive disease. The diagnosis of lymphoma was considered likely by the clinicians and, in three cases, the histologic slides were originally interpreted as malignant lymphoma by the referring pathologists. Although the architecture of these lesions appeared to be effaced on hematoxylin and eosin-stained sections, immunohistochemical analysis demonstrated preserved architecture with florid expansion of B-cell and T-cell compartments. In addition, clinical follow-up of these patients was benign, and gene rearrangement analysis in three lesions revealed no evidence of clonality. We conclude that the majority of lymphoid lesions in patients with CVID are benign. Immunohistochemical and gene rearrangement studies are particularly helpful in the assessment of cases of atypical lymphoid hyperplasia.

T-cell lymphoma in Singapore: pathology, clinical findings and association with HTLV-1 antibodies.
Of 128 cases of malignant lymphomas studied in Singapore between 1986 and 1988, 28 were identified as peripheral T-cell lymphomas. Sera from two of the 128 cases were positive for HTLV-1 antibodies and both cases had the clinical and pathological features of adult T-cell leukaemia/lymphoma. The pathological and clinical features of the 28 cases of peripheral T-cell lymphoma are presented in detail. Survival data indicated no significant difference between the low grade and high grade histological types. Three of the patients had previous or concomitant malignancies. The percentage of T-cell lymphomas associated with HTLV-1 infection in Singapore is low compared to those areas in which HTLV-1 is endemic.

A novel lymphoproliferative/autoimmune syndrome resembling murine lpr/gld disease.
In mice, the two distinct autosomal recessive genes lpr and gld can induce a syndrome characterized by autoantibody formation and the progressive accumulation of an unusual CD4-CD8- T cell population in peripheral lymphoid tissue. This phenotype does not precisely mirror any human disease. In this report we describe two patients with a progressive lymphoproliferative disorder associated with autoimmunity. The peripheral blood and lymph nodes of these patients contained large numbers of an unusual CD4-CD8- T cell population. These CD4-CD8- T cells express surface markers characteristic of mature peripheral blood T cells (CD3, CD2, CD5), express the alpha/beta form of the T cell receptor, and do not express surface markers characteristic of immature thymocytes (CD1) or NK cells (CD16, CD56). Functionally, these cells exhibited deficient proliferation and lymphokine production upon stimulation with mitogenic antibodies to CD3 or CD2. Both proliferation and lymphokine production could be augmented by co-stimulation with an antibody directed at the CD28 determinant. The clinical and immunological features of this syndrome resemble the lymphoproliferative/autoimmune disease seen in lpr and gld mice.

Conventional-dose salvage combination chemotherapy in patients relapsing with Hodgkin's disease after combination chemotherapy: the low probability for cure.
PURPOSE: The study was undertaken to evaluate clinical prognostic factors, probability of response to therapy, duration of response, and overall survival of patients with Hodgkin's disease relapsing from a chemotherapy-induced complete remission. PATIENTS AND METHODS: Study population comprised 107 patients with Hodgkin's disease treated with combination chemotherapy at the National Cancer Institute who relapsed after achieving a complete remission. RESULTS: Half of the relapses occurred within the first year of achieving complete remission; among patients in remission 5 years or longer, only 4% relapsed. The overall survival of the relapsed patients is projected to be 17% at 20 years, calculated from the date of relapse. Primary treatment regimen, presence of B symptoms, stage, sex, liver involvement, pleural involvement, marrow involvement, and histologic subtype did not affect the survival of relapsed patients. Only age at diagnosis (older or younger than 30 years) and length of initial remission (shorter or longer than 1 year) made a significant impact on survival. Patients whose initial remission was longer than 1 year had significantly higher complete response rates to salvage therapy, significantly more durable second remissions, and significantly longer survival than patients whose initial remission was shorter than 1 year. Survival beyond 11 years from relapse of patients with long initial remissions was 24%; for those with short initial remissions, 11% (P2 = .027). Despite the fact that with salvage therapy, patients with long initial remission had an 85% complete response rate to mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) with a disease-free survival of 45% at 20 years, acute leukemia and other treatment-related complications combined to lower the survival rate of this more favorable subset. CONCLUSIONS: These data with conventional-dose salvage therapy provide results for comparison with novel salvage approaches including myeloablative therapy with autologous marrow or peripheral-blood stem-cell support.

Mantle cell lymphoma: an update.
Mantle cell lymphoma is a distinctive pathologic entity that incorporates the previous histopathologic categories of centrocytic lymphoma and lymphocytic lymphoma of intermediate differentiation. These lymphomas are characterized by common histologic and immunologic characteristics that suggest derivation from the follicular mantle zone. Mantle cell lymphomas are characterized by the t(11;14) (q13;q32) translocation and its molecular counterpart bcl-1 rearrangement. This translocation activates a gene called BCL-1/PRAD-1. The identification of the BCL-1 gene product as a cyclin has added a new dimension to our understanding of the variety of mechanisms involved in lymphomagenesis.

Metastatic nasopharyngeal carcinoma initially presenting as cervical lymphadenopathy. A report of two cases that resembled Hodgkin's disease.
We describe two patients with nasopharyngeal carcinoma who initially presented with cervical lymphadenopathy. Lymph node biopsy specimens in each patient were initially diagnosed as Hodgkin's disease. In both cases, the neoplastic cells had large, vesicular nuclei with prominent eosinophilic nucleoli; some neoplastic cells were identified in lacunar spaces. In addition, numerous inflammatory cells were present, including eosinophils, lymphocytes, and plasma cells. At the time of referral, the correct diagnosis of metastatic carcinoma was made, and primary nasopharyngeal carcinomas were subsequently identified. The possibility of metastatic nasopharyngeal carcinoma should always be considered in adults with enlarged cervical lymph nodes that resemble Hodgkin's disease. The cytologic features of the malignant cells are the clue to the correct diagnosis. Immunophenotypic studies easily resolve this diagnostic dilemma if the possibility of metastatic nasopharyngeal carcinoma is considered.

The interrelationship of Hodgkin's disease and non-Hodgkin's lymphomas--lessons learned from composite and sequential malignancies.
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)

Hodgkin's disease coexistent with plasma cell dyscrasia.
We describe a case of Hodgkin's disease, mixed cellularity type, associated with nodal monotypic plasma cells and monoclonal serum gammopathy. Although plasma cells are often found in tissues involved by Hodgkin's disease and may be numerous, the occurrence of Hodgkin's disease with monotypic plasmacytosis and/or monoclonal serum gammopathy is rare. The simultaneous occurrence of Hodgkin's disease and monotypic plasma cell proliferation may represent a coincidental occurrence. However, previously we have described cases of Hodgkin's disease associated with B-cell non-Hodgkin's lymphoma, perhaps suggesting a relationship between the Reed-Sternberg and Hodgkin cells and B-lineage lymphoid cells. The case presented further extends these observations.

c-myc mRNA expression in minor salivary glands of patients with Sjögren's syndrome.
c-myc protooncogene is implicated in the pathogenesis of B cell lymphoid malignancies and high levels of c-myc mRNA expression are observed in activated blood mononuclear cells. Sjögren's syndrome (SS) is characterized by lymphocytic infiltrates of exocrine glands, remarkable B cell hyperreactivity and a strong predisposition to B cell neoplasia. In this study, c-myc protooncogene mRNA expression in 29 labial minor salivary gland biopsies from patients with primary SS and 15 controls was examined using in situ hybridization histochemistry. Two 40mer oligonucleotides from the 1st and the 2nd exon of the c-myc gene, labeled with 35S, were used as probes. To detect the origin of the cell hybridized with a c-myc probe, a combined immunochemistry in situ hybridization histochemistry technique was used. High c-myc mRNA expression was detected on acinar epithelial cells. c-myc did not correlate with c-fos and c-jun protein expression. Stronger c-myc mRNA expression was detected in labial salivary glands of patients with longer disease duration (p less than or equal to 0.002) and more intense T lymphocyte infiltrates (p less than 0.05) although these patients revealed no hypergammaglobulinemia. No correlation was observed between c-myc mRNA and B lymphocyte monoclonicity or lymphoma. In conclusion, strong c-myc mRNA expression was observed on epithelial cells of labial salivary glands from patients with primary SS. Our findings may indicate the presence of a reactivated virus hosted in these cells.

Angiocentric immunoproliferative lesions: a molecular analysis of eight cases.
Angiocentric immunoproliferative lesions (AILs) are believed to represent a unique type of extranodal malignant lymphoma on the basis of clinicopathologic and immunophenotypic evidence. However, molecular studies to assess clonality have been performed on a small number of cases. In this study we assessed the clonality of eight AILs using restriction fragment analysis, the Southern blot technique, and probes to assess the configuration of the T-cell receptor beta, gamma, and delta chain genes and the immunoglobulin heavy and K light chain genes. In addition, the presence of the Epstein-Barr (EB) viral genome was assessed by using both Southern blot analysis (seven cases) and polymerase chain reaction amplification (five cases). Our results demonstrate that gene rearrangements are rare in AILs. A clonal gene rearrangement was identified in only one case, a grade III AIL with a rearrangement of the T-cell receptor delta chain gene. In two additional AILs (both grade III), the EB viral genome was detected as a single band by Southern blot analysis with a probe derived from the terminal repeat region of the virus, suggesting that a single episomal configuration of the EB viral genome was present in each case, as would occur in a clonal population of infected cells. In the remaining cases there was no evidence of clonality, although EB sequences were detected in one of four cases using the polymerase chain reaction. The rarity or absence of gene rearrangements in AILs is difficult to explain if AILs are malignant, presumably monoclonal lymphomas. However, their frequent association with the EB virus may suggest an analogy between AILs and lymphoproliferative disorders that occur in immunosuppressed patients. These findings further emphasize the unique clinicopathologic aspects of AILs and may also be useful diagnostically in the differential diagnosis of lymphoproliferative disorders.

Determination of lineage and clonality in diffuse lymphomas using the polymerase chain reaction technique.
Malignant lymphomas of the diffuse mixed or diffuse large cell subtype are immunologically heterogeneous and morphologic features do not allow prediction of lineage. Applications of immunophenotypic and gene rearrangement techniques has greatly improved our ability to determine clonality and lineage. Nevertheless, some diffuse lymphomas are composed of numerous reactive cells accompanying a small clonal population, thereby making determination of clonality difficult, even with gene rearrangement techniques. In this study, we report two malignant lymphomas in which immunophenotypic and genotypic studies failed to elucidate evidence of clonality. In both cases, the polymerase chain reaction amplified segments of DNA containing the bcl-2/JH sequence, providing evidence of clonality and suggesting B-cell lineage. We conclude that the polymerase chain reaction technique may be useful in the diagnosis of some diffuse mixed and large cell lymphomas.

Lymphoblastic lymphoma presenting in cutaneous sites. A clinicopathologic analysis of six cases.
Six patients with malignant lymphoma of lymphoblastic type involving cutaneous sites at time of diagnosis are presented. Skin sites of the head and neck were involved in all patients and included the scalp (three patients), forehead (two patients), and malar region of the face (one patient). Two patients also had additional sites of skin disease (neck, breast, and anterior trunk). In two patients the skin was the predominant site of disease, whereas in the remaining patients staging workup revealed generalized lymphoma. The histologic findings in each patient were typical of lymphoblastic lymphoma; the neoplastic cells were small with blastic nuclear chromatin. In three patients the neoplastic cells were convoluted, and in three they were nonconvoluted. Immunophenotypically, four lymphomas were of pre-B cell type, and two lymphomas were of T cell type. There was no correlation between histologic features and the immunophenotype. Since the majority of lymphoblastic lymphomas are of T cell type, the predominance of pre-B cell tumors involving the skin may suggest that pre-B cell neoplasms have a predilection for cutaneous involvement. In further support of this hypothesis, both lymphomas that appear to have arisen in the skin had a pre-B cell immunophenotype.

Pseudolymphoma of the parapharyngeal space.
A case report of pseudolymphoma of the parapharyngeal space is presented, together with a literature review of pseudolymphoma and management suggestions for such lesions when they occur in the head and neck. To the best of the authors' knowledge, this represents the first case report of pseudolymphoma presenting within the parapharyngeal space. The key to management of these lesions is based on accurate diagnosis, with differentiation of pseudolymphoma from lymphocytic lymphoma, the disease process which it mimics.

Gene rearrangements in the diagnosis of lymphoma/leukemia. Guidelines for use based on a multiinstitutional study.
The demonstration of immunoglobulin or T-cell receptor gene rearrangements in human lymphoproliferative processes with the use of DNA hybridization has gained great popularity as a sensitive laboratory adjunct to diagnostic hematopathology. The fact that nearly all B- or T-cell malignant lymphomas and leukemias have one or more rearranged antigen receptor genes provides a biologic basis for a diagnostic test. To formally analyze the sensitivity, specificity, and reproducibility of gene rearrangements in the diagnosis of human lymphoproliferative disease, the authors conducted a large, multiinstitutional study. Through a blinded, controlled approach, gene rearrangement analysis of 275 cases was shown to carry a high correlation with conventional phenotyping and histologic diagnosis, with only minor false-positive and false-negative rates. Significantly, no rearrangements were detected in normal lymphoid tissues or carcinomas, sarcomas, or melanomas. In a randomized study of 50 cases, laboratory results showed a high rate of interlaboratory agreement, regardless of the level of previous experience. Furthermore, the reproducibility of interpretation of data (Southern blot autoradiograms) of 192 cases showed high concordance among 11 observers from multiple laboratories. Based on these findings, the authors propose a set of guidelines for interpretation of gene rearrangement analysis that, if carefully followed, renders this a highly reproducible, safe, and accurate addition to the diagnostic regimen for human lymphoproliferative processes.
