Abstract
Specimens from the gastrointestinal (GI) tract are among the most commonly encountered in routine pathology practice worldwide. It is well known that the luminal GI tract is home to various areas rich in mucosa-associated lymphoid tissue (MALT), whether native or acquired. The latter may be particularly problematic due to its well-known predisposing factors such as Helicobacter pylori infection and autoimmune conditions. Nevertheless, native GI structures are often the subject of query, particularly in conditions that may mimic lymphoproliferative conditions, including infectious and inflammatory diseases. Herein, we describe and share common clinicopathological findings in our daily practice that are challenging to distinguish from subtle low-grade neoplastic lymphoproliferative disorders.

Abstract
Epstein-Barr virus (EBV) is an oncogenic herpesvirus implicated in the pathogenesis of several malignant and non-malignant conditions. However, a number of fundamental aspects about the biology of EBV and the mechanism(s) by which this virus induces pathology remain unknown. One major obstacle has been the lack of a suitable animal model for EBV infection. In this study, using our recently established rabbit model of EBV infection, we examined the early events following primary EBV infection. We show that, both immunocompetent and immunosuppressed animals were readily susceptible to EBV infection. However, immunosuppressed animals showed marked splenomegaly and widespread infection. Following EBV infection, the virus primarily targeted naïve IgM+, CD20+, CD21+ and CD79a+ B cells. Infected cells expressed varying sets of viral latent/lytic gene products. Notably, co-expression of latent and lytic proteins in the same cell was not observed. Infected cells in type 0/1 latency (EBERs+), were small and proliferating (Ki67+). By contrast, cells in type 2/3 latency (LMP1+), were large, non-proliferating (Ki-67-) and p53+. Although infected B-cells were widely present in splenic follicles, they did not express germinal center marker, BCL-6. Taken together, this study shows for the first time, some of the early events following primary EBV infection.

Abstract
Chromogenic immunohistochemistry (immunostaining using an enzyme-labeled probe) is an essential histochemical technique for analyzing pathogenesis and making a histopathological diagnosis in routine pathology services. In neoplastic lesions, immunohistochemistry allows the study of specific clinical and biological features such as histogenesis, behavioral characteristics, therapeutic targets, and prognostic biomarkers. The needs for appropriate and reproducible methods of immunostaining are prompted by technical development and refinement, commercial availability of a variety of antibodies, advanced applicability of immunohistochemical markers, accelerated analysis of clinicopathological correlations, progress in molecular targeted therapy, and the expectation of advanced histopathological diagnosis. However, immunostaining does have various pitfalls and caveats. Pathologists should learn from previous mistakes and failures and from results indicating false positivity and false negativity. The present review article describes various devices, technical hints, and trouble-shooting guides to keep in mind when performing immunostaining.

Abstract
PURPOSE OF REVIEW Our understanding of risk factors and mechanisms underlying immunosuppression-related lymphoproliferative disorders continues to evolve. An increasing number of patients are living with altered immune status due to HIV, solid organ or hematopoietic stem cell transplant, treatment of autoimmune disease, or advanced age. This review covers advances in understanding, emerging trends, and revisions to diagnostic guidelines. RECENT FINDINGS The tumor microenvironment, including interactions between the host immune system and tumor cells, is of increasing interest in the setting of immunosuppression. While some forms of lymphoproliferative disease are associated with unique risk factors, common mechanisms are also emerging. Indolent forms, such as Epstein-Barr virus positive mucocutaneous ulcer, are important to recognize. As methods to modulate the immune system evolve, more data are needed to understand and minimize lymphoproliferative disease risk. A better understanding of individual risk factors and common mechanisms underlying immunosuppression-related lymphoproliferations will ultimately enable improved prevention and treatment of these disorders.

Soluble CD30, Acute Rejection, and Graft Survival: Pre- and 6-Month Post-Transplant Determinations-When Is the Best Time to Measure? Transplant Proc 2018; 50:728-736. [PMID: 29661425 DOI: 10.1016/j.transproceed.2018.02.025] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/23/2023]
Abstract
BACKGROUND Pretransplantation soluble CD30 (sCD30) has been shown to be a good predictor of acute rejection (AR) and graft loss. This study aimed to evaluate the effectiveness of sCD30 measured pretransplant and up to 6 months after transplantation as a predictor of AR, graft loss, and survival at 5 years post-transplantation. Subjects were patients receiving living donor renal transplants at Bonsucesso Federal Hospital (Rio de Janeiro) in 2006 and between August 2010 and May 2011. METHODS sCD30 was analyzed in samples collected pretransplantation and 7, 14, and 21, 28 days and 3, 4, 5, and 6 months post-transplantation from 73 kidney recipients. RESULTS Patients in the AR group did not present a positive correlation with the sCD30 levels pretransplant (P = .54); in the post-transplant period, the 7- to 14-day samples showed patients with AR had higher levels of this biomarker (P = .036). The graft survival in 5 years of follow-up was not different between groups. CONCLUSIONS The best time to predict AR using sCD30 is the 7- to 14-day sample; however, identifying and following the decrease of this biomarker from pre- to post-transplant seems to be better than just 1 measurement. The sCD30 post-transplant is another tool that may be used in monitoring patients after renal transplantation.

Classical Hodgkin lymphoma type post-transplant lymphoproliferative disorder in a kidney transplant recipient: a diagnostic pitfall. Int J Hematol 2018; 108:218-227.

Abstract
We report a case of classical Hodgkin lymphoma type post-transplant lymphoproliferative disorder (HL-PTLD) after kidney transplantation to highlight the difficulty of distinguishing this disorder from Hodgkin lymphoma-like PTLD (HL-like PTLD). Through this case report and literature review, we seek to clarify definitive pathologic features to differentiate these two conditions. A 38-year-old male kidney transplant recipient who had been receiving immunosuppressants was admitted to our hospital with unidentified high fever. Computed tomography images and blood tests indicated a lymphoproliferative disorder. Abdominal lymph node biopsy was performed, and microscopic examination revealed the presence of many large atypical cells in a background of dense T cell accumulation. The large, atypical cells were positive for Epstein-Barr Virus (EBV)-encoded small RNAs (EBER) in situ hybridization, EBV-LMP1, CD30 and PAX5, but negative for CD15, CD20 and CD45. Except for CD15-negativity, this immunohistochemical pattern was consistent with that of classical Hodgkin lymphoma. By close examination of the above immunoreactivities and the patient's subsequent chemosensitive clinical course, we finally made a diagnosis of HL-PTLD.

Abstract
Primary cutaneous large B‑cell lymphomas (PCBLT), EBV-positive large B‑cell lymphomas, not otherwise specified (EBV+ DLBCL, NOS), and primary cutaneous intravascular large B‑cell lymphomas (PCIVLBL) are recognized as cutaneous lymphomas with intermediate to poor prognosis. Differentiation from indolent B‑cell lymphomas or other pathologies of the skin can be complex, both clinically and histologically, but vital for the outcome of the patient. The combination of immunotherapy and polychemotherapy regimens, such as R‑CHOP, has led to significant improvements in prognosis, especially in diffuse large B‑cell lymphomas. Therapeutic decisions need to be individually made for each patient, ideally within an interdisciplinary tumor conference. Immunosenescence may be an important factor in the pathogenesis of EBV+ DLBCL, NOS in elderly individuals. Their prognosis is less favorable than that of patients with EBV-negative PCBLT, whereby this has been observed particularly in elderly patients. One third of patients with PCIVLBL progress to systemic disease. The occurrence of nodal manifestation is rarely observed. Symptoms may vary depending on the organ system involved. Currently there are no evidence-based therapy recommendations due to the rarity of the disease. EBV-positive mucocutaneous ulcer is a new provisional category in the current WHO classification for lymphoid neoplasms. It has been segregated from EBV+ DLBCL, NOS due to its self-limiting course and good response to conservative therapy.

Abstract
We describe a series of Epstein Barr virus (EBV)-positive circumscribed, ulcerative lesions associated with various types of immunosuppression (IS). The study group (26 patients) comprised 10 males and 16 females, median age 77 years (range 42 to 101). IS in 9 cases included azathioprine (AZA), methotrexate (MTX) or cyclosporin-A (CyA). Seventeen patients had age-related immunosenescence. Patients presented with isolated sharply circumscribed ulcers involving oropharyngeal mucosa (16), skin (6), and gastrointestinal tract (4). Lesions were histologically characterized by a polymorphous infiltrate and atypical large B-cell blasts often with Hodgkin/Reed-Sternberg (HRS) cell-like morphology. The B cells showed strong CD30 and EBER positivity, some with reduced CD20 expression, in a background of abundant T cells. CD15 was positive in 43% of cases (10/23). The pathologic features were identical regardless of the anatomic site or cause of IS. Polymerase chain reaction revealed 39% (7/18) clonal Ig gene rearrangements with 38% (6/16) and 31% (5/16) clonal and restricted T-cell patterns, respectively. Twenty-five percent of patients (5/20) received standard chemotherapy and/or radiotherapy. Forty-five percent (9/20) regressed spontaneously with no treatment and 15% (3/20) were characterized by a relapsing and remitting course. All of the iatrogenic lesions (6/6) with available follow-up responded to reduction of IS. All patients achieved complete remission with no disease-associated deaths over a median follow-up period of 22 months (range 3 to 72). We propose EBV-positive mucocutaneous ulcer as a newly recognized clinicopathologic entity with Hodgkin-like features and a self-limited, indolent course, generally responding well to conservative management. Association with various forms of IS implies a common pathogenetic mechanism. The localized nature of the disease may be owing to a minimal and localized lapse in immunosurveillance over EBV.

Abstract
Because of its rarity, pathologic and clinical features of Hodgkin lymphoma-like posttransplant lymphoproliferative disorder (HL-like PTLD) are not well understood, and it is unclear whether its biological behavior is more closely related to classical Hodgkin disease or to monomorphic B-cell PTLD. The authors compared 6 cases of HL-like PTLD with 5 cases of monomorphic B-cell PTLD for differences in histology, immunophenotype, and clinical behavior. Histologically, all cases of HL-like PTLD resembled classical HL with typical Reed-Sternberg (RS) cells and a cellular background mimicking mixed cellularity subtype. CD45 was absent on RS-like cells, but the expression pattern of B-cell-associated markers Oct-2 and BOB.1 resembled monomorphic B-cell PTLD. Whereas Epstein-Barr virus early RNA expression is normally restricted to RS cells of classical HL, it was expressed in both RS-like cells and background lymphocytes in HL-like PTLD. Although all patients diagnosed with monomorphic B-cell PTLD show no evidence of disease following treatment, half of the patients with HL-like PTLD relapsed or died, indicating a more aggressive clinical behavior. The findings suggest that HL-like PTLD represents a distinct clinicopathologic entity with an aggressive clinical course.

Abstract
Posttransplant lymphoproliferative disorders (PTLDs), a heterogeneous group of monoclonal or polyclonal lesions, occur in immunosuppressed patients after solid organ or bone marrow transplantation. Although most PTLDs are Epstein-Barr virus (EBV)+ and seem to represent EBV-induced proliferations of monoclonal (or less often polyclonal) B, T, or plasma cells, a subset of PTLDs is EBV-. Because Kaposi sarcoma-associated herpesvirus/human herpesvirus 8 (KSHV/HHV-8) has been described in association with the development of hematolymphoid and nonhematolymphoid neoplasms in HIV+ patients, we investigated whether there is an association between KSHV/HHV-8 and PTLDs. Formalin-fixed, paraffin-embedded tissue from 52 confirmed PTLD cases were analyzed immunohistochemically for expression of KSHV/HHV-8 latent nuclear antigen (LNA)-1 protein and by polymerase chain reaction-hybridization analysis for the KSHV/HHV-8 genome. The PTLD subtypes included 12 with early lesions (1 plasmacytic hyperplasia and 11 infectious mononucleosis-like), 10 polymorphic, 23 monomorphic (5 Burkitt, 14 diffuse large B-cell lymphoma, 1 plasmacytoma, 1 multiple myeloma, and 2 T-cell), 1 Hodgkin lymphoma (HL), 5 HL-like lesions, and 1 unclassified or other. None of the 51 tested specimens showed expression of KSHV/HHV-8 LNA-1. Furthermore, all 46 specimens tested demonstrated complete absence of the KSHV/HHV-8 genome. Our data clearly indicated that KSHV/HHV-8 is not associated with PTLDs.

Abstract
The development of lymphomas after SOT is a well-known complication of the immunosuppressive therapy necessary to prevent graft rejection. Epstein-Barr virus plays a central role in the pathogenesis of lymphomas because of its ability to transform infected cells. Differentiating PTLD from malignant lymphomas, especially HL can be challenging. We report on two patients, who developed EBV-associated lymphomas several years after SOT. A histological examination of lymph nodes led to a diagnosis of HL in both patients, who were started on chemotherapy according to current treatment protocols. A rapid and complete remission in one patient prompted us to analyze the expression pattern of EBV-latency genes. In this patient, the EBV expression profile revealed a latency type III suggesting the diagnosis of Hodgkin-like PTLD. The other patient required six courses of chemotherapy plus radiotherapy to reach a complete remission. In his tumor cells, a restricted EBV-latency type II pattern was found, suggesting a diagnosis of classical HL. These two cases demonstrate that in post-transplant lymphomas with histological features of HL, an analysis of the expression pattern of EBV proteins might aid in the differentiation between PTLD and HL.

Abstract
Age-related Epstein-Barr virus-positive (EBV(+)) B-cell lymphoproliferative disorder (ALPD) is a disease entity identified from a large-scale re-survey of cases diagnosed as diffuse large B-cell lymphoma. ALPD is a group of EBV(+) polymorphic B-cell lymphoma typically seen in elderly patients. An age-associated decline in host immunity against EBV might be partly responsible for the pathogenesis of ALPD. Histologically, ALPD is often characterized by a minor proportion of EBV-encoded RNA-positive tumor cells in a background of extensive cellular infiltration, similar to that of classical Hodgkin's lymphoma. In contrast to Hodgkin and Reed-Sternberg cells, ALPD tumor cells are clearly positive for B cell markers CD20 and/or CD79a. Hodgkin and Reed-Sternberg cells produce various chemokines, including CCL17 and CCL22, that attract chemokine receptor CCR4-expressing Th2 cells and regulatory T cells. Previously, we have shown that EBV-immortalized B cells also produce CCL17 and CCL22 through latent membrane protein 1 (LMP1)-mediated activation of nuclear factor kappaB. Here we examined expression of CCL17 and CCL22 in ALPD. ALPD tumor cells were often heterogeneous in size in accordance with the differential expression of EBV latent genes at the single cell level. LMP1-expressing tumor cells were typically large in size and selectively positive for CCL17 and CCL22. CCR4(+) cells and forkhead box protein 3(+) regulatory T cells were abundantly present, and the majority of forkhead box protein 3(+) cells were CCR4(+). Collectively, our data show production of CCL17 and CCL22 by LMP1(+) large-sized tumor cells and accumulation of CCR4-expressing cells including regulatory T cells in ALPD.

Abstract
We describe a case of Hodgkin lymphoma developing in a 9-year-old girl with polyarticular, rheumatoid factor-positive juvenile idiopathic arthritis treated with methotrexate (MTX), prednisone, and naproxen for 5 years. Pathologic and molecular analyses revealed that the Hodgkin cells contained Epstein-Barr virus and the viral DNA was monoclonal. She achieved complete remission after MTX withdrawal, chemotherapy, and radiation. To the best of my knowledge, this is the sixth report of Hodgkin lymphoma in patients with juvenile idiopathic arthritis receiving low dose MTX therapy.

Abstract
Although Hodgkin lymphoma-like posttransplantation lymphoproliferative disorder (HL-like PTLD) has been grouped with classic Hodgkin lymphoma type PTLD (HL-PTLD), controversy remains as to whether it is truly a form of HL or whether it should be more appropriately classified as a form of B-cell PTLD. Because only few cases of HL-like PTLD have been reported, their pathologic nature and clinical behavior have not been well defined. This report characterized 5 cases of HL-like PTLD with respect to their immunophenotype, EBV status, clonality, and clinical outcome. All of the patients were male, with ages ranging from 1.5 to 55 years at diagnosis. PTLD developed from 4 months to 6 years following solid organ transplantation (3 hearts, 1 kidney, 1 liver), and involved both nodal and extranodal sites. All were EBV-related (EBER+) with the large neoplastic cells CD20/CD79a positive but CD15 negative. Immunoglobulin gene rearrangements were detected in 3 of 5 tested. All patients were managed by initial reduction/withdrawal of immunosuppression, with 2 also receiving chemotherapy for non-HL. Three patients died of progressive disease within 2 to 3 months after diagnosis, 1 is alive and well 2 years later, and the fifth was disease free but died of unrelated causes (graft coronary disease) 2 years later. We conclude that, although HL-like PTLD morphologically simulates classic HL PTLD, there are important immunophenotypic, molecular genetic, and clinical differences, suggesting it is in fact most often a B-cell PTLD. Distinction between HL and HL-like PTLD may be important for clinical management and prognosis.

Abstract
Posttransplantation lymphoproliferative disorders (PTLD) are a heterogeneous group of monoclonal or polyclonal lymphoproliferative lesions that occur in immunosuppressed recipients following solid organ or bone marrow transplantation, including 4 categories: (1) early lesions (reactive plasmacytic hyperplasia, and infectious-mononucleosis-like PTLD), (2) polymorphic PTLD, (3) monomorphic PTLD (including B-cell neoplasms and T-cell neoplasms), and (4) Hodgkin lymphoma (HL) and HL-like PTLD in the current World Health Organization classification. Although HL-like PTLD has been grouped with classic HL PTLD, controversy remains as to whether it is truly a form of HL or whether it should be more appropriately considered as a form of B-cell PTLD. The current available literature data indicate the presence of important immunophenotypic, molecular genetic, and clinical differences between HL PTLD and HL-like PTLD, suggesting that HL-like PTLD is in fact most often a form of B-cell PTLD. Distinction from true HL may be important for clinical management and prognosis.

Abstract
Classical Hodgkin lymphoma (HL) is a rare complication after solid organ transplantation. We describe the first case of a patient developing CD20-positive HL after renal transplantation treated with the monoclonal antibody rituximab. Treatment with single agent rituximab led to partial remission. Subsequent combined modality treatment consisting of chemotherapy (adriamycin, bleomycin, vindesin and dacarbacin), immunotherapy (rituximab) and involved field irradiation achieved complete remission. Different therapeutic strategies in the treatment of patients developing lymphoproliferative disease - and particularly HL - after solid organ transplantation are discussed.

Abstract
Lymphoid malignancies such as post-transplant lymphoproliferative disease (PTLD) are a major complication of solid organ transplantation. Hodgkin's lymphoma (HL) is not part of the typical spectrum of PTLD, but has rarely been reported as a separate complication. We report a case of HL occurring after previous PTLD in a renal transplant recipient. A 9-yr-old girl with end-stage autosomal recessive polycystic kidney disease received a cadaveric renal transplant at 1 yr of age. She developed polymorphic PTLD localized to the bone marrow at 6 yr post-transplant. She was treated with reduction of immunosuppression and alpha-interferon. No chemotherapy or anti-B cell antibody was administered. The PTLD resolved and kidney graft function remained stable. At 9 yr post-transplant, she presented again with fever of 2 wk duration, associated with enlarged lymph nodes at multiple sites. A lymph node biopsy revealed the presence of classic Reed Sternberg cells positive for CD15, CD30 and EB RNA. She was treated with standard combination chemotherapy for HL with COPP/ABV. All immunosuppressive agents were discontinued except for low dose prednisone. The patient had an excellent response, with resolution of her lymphadenopathy and maintenance of stable graft function. RS like cells have been reported in the setting of PTLD, but these cells possess an activated B cell phenotype, are EBV negative and CD15 negative. True HL following PTLD has been reported in only three previous cases, with good response to standard chemotherapy in each.

Abstract
Epstein-Barr virus is a tumorigenic herpes virus that is ubiquitous in the adult population. The virus is generally spread to and between young children through salivary contact, and only causes clinical illness where primary infection is delayed until adolescence or beyond, when an intense immunopathological reaction leads to the symptoms of infectious mononucleosis in roughly 50% of cases. More than 90% of the world's population carry Epstein-Barr virus as a life-long, latent infection of B lymphocytes. Recent data show that by mimicking B-cell antigen-activation pathways the virus enters the long-lived memory B lymphocyte pool where it evades immune elimination by severely restricting its own gene expression. By influencing B-cell survival mechanisms Epstein-Barr virus may induce tumours such as B lymphoproliferative disease and Hodgkin's disease. Vaccines are being developed to prevent and/or treat these conditions, but an animal model is required to study pathogenesis before a rational vaccine strategy can be formulated.

Abstract
CD79 is composed of CD79a and CD79b components expressed almost exclusively on B cells and B-cell neoplasms. CD79a and CD79b expression precedes immunoglobulin (Ig) heavy-chain gene rearrangement and CD20 expression during B-cell ontogeny and disappears later than CD20 in the late (plasma cell) stage of B-cell differentiation. Therefore, antibodies to CD79a and CD79b are useful in the differential diagnosis of B-cell neoplasms from T-cell neoplasms or myeloid neoplasms, or L and H lymphocyte predominance Hodgkin's lymphoma from classic Hodgkin's lymphoma. In addition, CD79a and CD79b antibodies are useful markers in the diagnosis of precursor B-acute lymphoblastic leukemia (pre-B-ALL) because many of these tumors are negative for other B-cell markers, such as CD20 and CD45RA. Furthermore, for B-cell neoplasms, wherein CD20 expression is aberrantly lost, such as in diffuse large B-cell lymphoma, or for B-cell neoplasms after CD20-antibody therapy, CD79a may be used as a first-line B-cell marker for the diagnosis. In this review, the authors discuss the molecular biology of CD79 and the frequency and usefulness of CD79 expression in these neoplasms.

Abstract
AIMS Lymphoproliferative disorders (LPDs) are a severe complication in primary immunodeficiency and post-transplant patients. In primary immunodeficiency patients, LPDs are not well-known and, thus, we tried to evaluate their distinctive features and to determine prognostic factors predictive of clinical outcome by comparison with LPDs in post-transplant children. METHODS AND RESULTS Clinical records and histopathology of 18 LPDs occurring in primary immunodeficieny children were compared with those of 10 LPDs in post-transplant children, together with results of in-situ hybridization for the detection of Epstein-Barr virus (EBV)-RNA and molecular biological techniques. LPDs were frequently extranodal, EBV-associated, and were more commonly pleomorphic in primary immunodeficiency than in post-transplant patients. A low T-cell count and abnormal T-cell function indicated bad prognosis in both groups. Polymorphic LPDs (PLPDs) were most frequent (n = 19), whereas lymphomas were rare (n = 7), and pseudo-tumoral lymphoid hyperplasias (n = 2) were observed only in primary immunodeficiency. Comparative p53/bcl-2 staining revealed a p53 overexpression in lymphomas compared with PLPDs; CD20/CD79a showed a similar staining in lymphomas, whereas PLPD expressed mainly CD20. TCR and IgH rearrangements did not help in distinguishing PLPDs from lymphomas, but detection of IgH clonality by Southern blot indicated poor prognosis, whereas oligoclonality by Southern blot regardless of PCR clonality and especially a polyclonal profile by Southern blot and PCR indicated a relatively good prognosis. CONCLUSIONS This study documents the pleomorphism of LPDs in primary immunodeficiency compared to post-transplant children, even if some LPDs are similar in both groups (PLPDs). No criteria are useful enough to ascertain the diagnosis of malignancy in this series. Some molecular biological criteria help to predict the clinical outcome which, nevertheless, seems to depend more on the degree of immunosuppression and on T-lymphocyte presence and function.

Abstract
Post-transplant lymphoproliferative disorders (PTLD) are a consequence of the immunosuppressive therapy following organ transplant. We describe a patient who developed PTLD seven years after liver transplant and while receiving cyclosporine and prednisone. Magnetic resonance imaging demonstrated a paraspinal mass extending from T11 to L1. Microscopically, this was composed of a diffuse infiltrate of small to intermediate sized T-lymphocytes with clusters of large anaplastic tumor cells with amphophilic cytoplasm, large irregular nuclei and prominent nucleoli. A high mitotic rate and atypical mitotic figures were noted in the clusters of large cells. Flow cytometric and immunohistochemical analysis failed identify either a monoclonal B-cell population or a T-cell population with aberrant expression of the T-cell surface markers. Strong positivity for CD30 and focal staining for epithelial membrane antigen (EMA) of the large cells was seen. Leukocyte common antigen (LCA), cytokeratin, vimentin, monocyte/macrophage and B- and T-markers were negative. The small lymphoid cells were positive for CD3, MT-1 and UCHL-1. Based on the immunophenotypic and morphological evaluation, this was characterized as a T-cell rich PTLD. PCR analysis identified a monoclonal population of B-cells. This unusual case emphasizes the morphological and immunophenotypic diversity of PTLD. The utility of PCR analysis in the evaluation of PTLD is also demonstrated.

Abstract
One of the characteristic features of Hodgkin's disease (HD) is the presence of a small population of often bizarre-looking large mono- or multinucleated Hodgkin and Reed-Sternberg (HRS) cells within the affected tissue. Recent cytogenetic investigations, studies of Epstein-Barr virus (EBV) genomes present in HRS cells, and analyses of Ig gene rearrangements amplified from single, micromanipulated HRS cells show that these cells largely represent clonal populations. The finding of Ig gene rearrangements in HRS cells in most cases of HD identifies B cells as the precursors of HRS cells in most if not all cases. Furthermore, the presence and pattern of somatic mutations within the rearranged Ig genes show that HRS cells in classical (i.e. nodular sclerosis, mixed cellularity, and lymphocyte depletion HD) as well as lymphocyte predominant (LP) HD originate from germinal center (GC) B cells. Ongoing somatic mutation and evidence for selection link HRS cells from LP HD to a mutating, antigen-selected GC B cell. In classical HD, the finding of "crippling" mutations and lack of stringent selection for antigen receptor expression suggests that in this case HRS cells are derived from a compartment of GC B cells that were destined to die but escaped apoptosis by some transforming event. One candidate for the latter is EBV infection.
