Abstract
Post-transplant lymphoproliferative disease (PTLD) is a life-threatening complication among kidney transplant recipients. The clinical presentation of patients with PTLD is highly variable. The type of PTLD and the area of involvement determine its presentation, which includes constitutional symptoms such as fever, weight loss, fatigue, and other symptoms related to dysfunction of involved organs, or compression of surrounding structures. Most present with extranodal masses involving the gastrointestinal tract (stomach, intestine), lungs, skin, liver, central nervous system, and the allograft itself. In our case, a 33-year-old woman developed Epstein-Barr virus-negative PTLD plasmablastic lymphoma (PbL) in her right breast and small intestine presenting as intestinal obstruction, 15 years after renal transplant. Her condition was managed with intestinal mass resection and chemotherapy. A follow-up positron emission tomography scan showed near-complete resolution. Thus, PTLD should always be kept in mind in renal transplant recipients who present with features of a mass effect involving any organ.

Abstract
Plasmablastic lymphoma (PBL) is an uncommon and aggressive type of mature B cell lymphoma rarely involving gastrointestinal (GI) tract. Here, we describe a case of PBL involving the colon in HIV/Epstein-Barr virus negative immunocompetent patient who presented with anaemia and weight loss but no significant GI symptoms. It emphasises that even in the absence of classical risk factors, one should consider possibility of this condition as this is potentially curable. Also, we would like to highlight the diagnostic and treatment challenges of such an aggressive lymphoma in a frail elderly patient with multiple comorbidities.

Abstract
EBV is the first known oncogenic virus involved in the development of several tumors. The majority of the global population are infected with the virus early in life and the virus persists throughout life, in a latent stage, and usually within B lymphocytes. Despite the worldwide diffusion of EBV infection, EBV-associated diseases develop in only in a small subset of individuals often when conditions of immunosuppression disrupt the balance between the infection and host immune system. EBV-driven lymphoid proliferations are either of B-cell or T/NK-cell origin, and range from disorders with an indolent behavior to aggressive lymphomas. In this review, which is divided in three parts, we provide an update of EBV-associated lymphoid disorders developing in the gastrointestinal tract, often representing a challenging diagnostic and therapeutic issue. Our aim is to provide a practical diagnostic approach to clinicians and pathologists who face this complex spectrum of disorders in their daily practice. In this part of the review, the chronic active EBV infection of T-cell and NK-cell type, its systemic form; extranodal NK/T-cell lymphoma, nasal type and post-transplant lymphoproliferative disorders are discussed.

Abstract
The incidence of lymphomas is increased in people living with HIV (PLWH). Aggressive B-cell non-Hodgkin lymphomas (NHLs) are the most common and are considered an AIDS-defining cancer (ADC). Although Hodgkin lymphoma (HL) is not considered an ADC, its incidence is also increased in PLWH. Among all HIV-related lymphomas (HRL), the prevalence of Epstein-Barr virus (EBV) is high. It has been shown that EBV is involved in different lymphomagenic mechanisms mediated by some of its proteins, contributing to the development of different lymphoma subtypes. Additionally, cooperation between both HIV and EBV can lead to the proliferation of aberrant B-cells, thereby being an additional lymphomagenic mechanism in EBV-associated HRL. Despite the close relationship between EBV and HRL, the impact of EBV on clinical aspects has not been extensively studied. These lymphomas are treated with the same therapeutic regimens as the general population in combination with cART. Nevertheless, new therapeutic strategies targeting EBV are promising for these lymphomas. In this article, the different types of HRL are extensively reviewed, focusing on the influence of EBV on the epidemiology, pathogenesis, clinical presentation, and pathological characteristics of each lymphoma subtype. Moreover, novel therapies targeting EBV and future strategies to treat HRL harboring EBV are discussed.

Abstract
Plasmablastic lymphoma is a rare B-cell lymphoma that is mainly associated with immunocompromised patients, such as those affected with human-immunodeficiency virus (HIV) or those who have received solid organ transplants; however, it has also been documented in immunocompetent patients. Moreover, there is also a strong association with Epstein-Barr virus (EBV). Although mainly found in the oral cavity, a few cases were documented to affect the gastrointestinal tract, and of those, only three cases were found to involve the esophagus, and we present the fourth case in a 48-year-old HIV-positive male.

Abstract
Introduction: Post-transplant lymphoproliferations (PTL) are a severe complication of solid organ transplants. Their locations can be extra-nodal. Observation: The diagnosis and management of a non-Hodgkin's plasmablastic lymphoma of mandibular localization affecting a 66-year-old kidney transplanted patient are reported here. Comment: The main risk factors for non-Hodgkin lymphoma are immunosuppression and infection with Epstein-Barr virus. Clinical and radiographic examinations, which are not specific, must be supplemented by a histological examination. Treatment which is not consensual will most often consist of a reduction in immunosuppression coupled with chemotherapy. Conclusion: Despite a constant evolution in the incidence and clinical picture of post-transplant lymphomas, the role of the dentist remains essential in the early detection of lesions.

Abstract
The pathogenesis of plasmablastic lymphoma (PBL) involves the Epstein-Barr virus (EBV), human immunodeficiency virus (HIV), and MYC gene aberrations. We aimed to determine the EBV latent infection pattern and frequency of MYC gene aberrations in PBLs. Immunohistochemistry was performed using antibodies for EBNA1, EBNA2, and LMP1 while fluorescence in situ hybridization was performed using a MYC probe. The patient cohort comprised 49 adult cases (44 were HIV-positive and three were HIV-negative). Forty-one cases were EBV-positive with 11 EBNA1-positive cases, all cases EBNA2-negative, and four LMP1-positive cases. Latency 0 was determined in 29 cases, latency I in eight cases, and latency II in four cases. The MYC gene was rearranged in eight cases, showed copy number alterations in 11 cases and, no rearrangement in 11 cases. This is the largest cohort of PBLs from South Africa to show a predominantly restricted EBV latency pattern with MYC gene aberrations as a common finding.

Abstract
CONTEXT.— Plasmablastic morphology can be seen in several uncommon lymphoproliferative neoplasms. Sometimes it is difficult to distinguish these neoplasms from each other. OBJECTIVE.— To review the current understanding of major lymphoproliferative neoplasms with plasmablastic morphology; summarize the clinical, morphologic, immunophenotypic, cytogenetic, and molecular characteristics of each disease entity; and highlight a practical approach for differential diagnosis. DATA SOURCES.— Peer-reviewed medical literature and the authors' personal experience. CONCLUSIONS.— Plasmablastic lymphoma; plasmablastic myeloma; primary effusion lymphoma; human herpesvirus 8-positive diffuse large B-cell lymphoma, not otherwise specified; and anaplastic lymphoma kinase (ALK)-positive large B-cell lymphoma are major lymphoproliferative neoplasms with plasmablastic morphology. These neoplasms share many common morphologic and immunophenotypic characteristics. Definitive diagnosis requires a thorough understanding of disease phenotype and diagnostic criteria of each category. Recognition of expression pattern of Epstein-Barr virus-encoded small RNA, human herpesvirus 8, and ALK in these neoplasms is critical for diagnosis in cases with typical presentation. Additional ancillary studies and clinical findings may help in difficult cases.

Abstract
Epstein-Barr virus (EBV) is a common pathogen infecting people primarily early in life. The virus has the ability to persist throughout a person's life, usually in B lymphocytes. Conditions of immunodeficiency as well as the introduction of immunosuppressive therapies and the advent of transplant technologies has brought immunodeficiency-associated lymphoproliferative disorders into view, which are often driven by EBV. The group of EBV-associated lymphoproliferative disorders includes different entities, with distinct biological features, ranging from indolent disorders, which may even spontaneously regress, to aggressive lymphomas requiring prompt and adequate treatment. These disorders are often diagnostically challenging due to their overlapping morphology and immunophenotype. Both nodal and extra-nodal sites, including the gastrointestinal tract, may be involved. This review, divided in three parts, summarizes the clinical, pathological, molecular features and treatment strategies of EBV-related lymphoproliferative disorders occurring in the gastrointestinal tract and critically analyzes the major issues in the differential diagnosis. In this part of the review, we discuss plasmablastic lymphoma, extra-cavitary primary effusion lymphoma and Burkitt lymphoma.

Abstract
The diagnosis of plasmablastic lymphoma (PBL), plasmablastic myeloma (PBM), and plasmablastic neoplasm (PBN) may be arbitrary in some cases because these entities can be indistinct. We conducted this scoping review to investigate heterogeneity in diagnostic criteria used in previous studies and validate the diagnostic results of previous diagnostic algorithms and the algorithm we developed, which also includes diagnosis of PBN. Using the PRISMA Extension for Scoping Reviews, we analyzed literature published between September 2017 and April 2020. We identified a total of 163 cases (128 PBL, 32 PBM, and 3 PBN) from 77 case reports and 8 case series. We found that diagnostic criteria in the literature varied for PBL but were consistent for PBM. Our algorithm was the first attempt to include PBN in a complete structure. The results of the three diagnostic algorithms varied significantly. Hematologists and pathologists should pay more attention to the differential diagnosis of PBL, PBM, and PBN.

Abstract
Plasmablastic lymphoma (PBL) represents a rare and aggressive lymphoma subtype frequently associated with immunosuppression. Clinically, patients with PBL are characterized by poor outcome. The current understanding of the molecular pathogenesis is limited. A hallmark of PBL represents its plasmacytic differentiation with loss of B-cell markers and, in 60% of cases, its association with Epstein-Barr virus (EBV). Roughly 50% of PBLs harbor a MYC translocation. Here, we provide a comprehensive integrated genomic analysis using whole exome sequencing (WES) and genome-wide copy number determination in a large cohort of 96 primary PBL samples. We identify alterations activating the RAS-RAF, JAK-STAT, and NOTCH pathways as well as frequent high-level amplifications in MCL1 and IRF4. The functional impact of these alterations is assessed using an unbiased shRNA screen in a PBL model. These analyses identify the IRF4 and JAK-STAT pathways as promising molecular targets to improve outcome of PBL patients. Plasmablastic lymphoma (PBL) is an aggressive lymphoma subtype characterized by poor prognosis but the molecular knowledge of the disease is limited. Here, the authors perform whole exome sequencing and copy number determination of primary samples highlighting IRF4 and JAK-STAT pathways as therapeutic targets for PBL.

Abstract
Plasmablastic lymphomas are high-grade lymphomas most commonly observed in the oral cavity. Their association with HIV-infected patients is now well-known. The occurrence of plasmablastic lymphomas in extra-oral sites in immunocompetent patients is exceedingly rare. We aim to document such a rare case in a 69-year- old female in the gastrointestinal tract along with lymphomatous effusion of the pleural cavity. The discussed case also needs a mention for its unique cytomorphological features. The diagnosis was confirmed by immunohistochemical stains, which play a vital role in the accurate diagnosis of plasmablastic lymphomas and their distinction from other anaplastic non-Hodgkin lymphomas.

An unusual case of paediatric plasmablastic lymphoma presenting with malignant effusion and the challenges in its diagnosis. Diagn Cytopathol 2021; 49:E389-E394. [PMID: 34296830 DOI: 10.1002/dc.24829] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2021] [Revised: 07/03/2021] [Accepted: 07/08/2021] [Indexed: 11/11/2022]
Abstract
Plasmablastic lymphoma (PBL) is an aggressive non-Hodgkin lymphoma occurring commonly in the oral mucosa and jaw of human immunodeficiency virus (HIV) positive adult males. PBL is not a common occurrence in children and a presentation with malignant effusion is rarely reported. Herein, we share our experience in the challenges confronted in the diagnosis of PBL in a 6-year-old, HIV positive boy presenting with malignant pleural and peritoneal effusions along with gum hypertrophy, lymphadenopathy and paranasal sinus mass. Amenability of pleural effusion to exfoliative cytology led to an initial cytological examination demonstrating large atypical lymphoid cells with plasmacytoid morphology and a plasmablastic variant of Burkitt lymphoma was initially considered. However immunophenotyping by flowcytometry (FCM) and a cell block immunohistochemical evaluation of the serous effusion suggested a plasma cell immunophenotype and a diagnosis of PBL was favored. A subsequent biopsy from the paranasal sinus mass confirmed the diagnosis of PBL but showed tumour cell angiocentricity on morphology and CD45 expression on immunohistochemistry (IHC), both unusual features in PBL. A CD20 negative/MUM-1 positive immunoprofile and presence of a solid tumour mass in a typical location in addition to malignant effusion substantiated the diagnosis of PBL. The patient was offered HAART (highly active antiretroviral therapy) and chemotherapy and is on follow-up. Paediatric PBL with malignant effusion is rarely reported and this case stresses the importance of use of a multimodality diagnostic approach for an accurate diagnosis.

Case Report: Successful Management of a Refractory Plasmablastic Lymphoma Patient With Tislelizumab and Lenalidomide. Front Immunol 2021; 12:702593. [PMID: 34322131 PMCID: PMC8312258 DOI: 10.3389/fimmu.2021.702593] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2021] [Accepted: 06/25/2021] [Indexed: 01/15/2023] Open
Abstract
Plasmablastic lymphoma (PBL) is a rare and aggressive hematological malignancy. PBL commonly occurs in immune incompetent patients, such as those with human immunodeficiency virus (HIV), post-transplant status, or immunosenescence. Given its rarity, there is no specific standard treatment for PBL. However, small case series have shown that intensive chemotherapies combined with anti-myeloma agents such as bortezomib and lenalidomide were effective in treating PBL. Unfortunately, some fragile patients could not tolerate intensive chemotherapeutic regimens, especially the elderly patients. Here we presented a 76-year-old female PBL patient refractory to miniCHOP regimen combined with bortezomib but achieved complete remission when treated with tislelizumab combined with lenalidomide, indicating that immune therapy may be a potential treatment for PBL. To our knowledge, this is the first chemoresistant PBL patient that has been successfully treated with checkpoint inhibitor plus lenalidomide, thus providing new insight towards PBL management.

Abstract
Introduction: Plasmablastic lymphoma (PBL) is a rare form of B-cell lymphoma typically seen in patients with underlying immunosuppression such as HIV, autoimmune disease, and organ transplantation. PBL in HIV-positive patients usually originates from the gastrointestinal tract, with a predilection for the oral cavity. Bladder involvement by PBL is exceedingly rare, and cast nephropathy due to κ light chain-secreting PBL has not been reported previously. Case report: We report a patient who presented with acute kidney injury (AKI) in the setting of HIV, and was found to have a bladder tumor. Bladder pathology revealed a high-grade PBL with κ light chain restriction. Renal biopsy showed κ light chain cast nephropathy, presumably secondary to κ light chain-secreting PBL. Conclusion: Although the prognosis of PBL is poor, our patient recovered from AKI, achieved complete hematologic remission with chemotherapy, and underwent successful autologous stem cell transplant.

Abstract
BACKGROUND Plasmablastic lymphoma (PBL) is an aggressive neoplasm that commonly develops in HIV-positive patients, usually affecting the oral cavity. EBV is present in the majority of cases, therefore, playing an important role in the pathogenesis of this neoplasm. METHODS PBL diagnosed from 2000 to 2020 were retrieved from the archives of the Department of Oral Pathology and Oral Biology at the University of Pretoria, South Africa. The patients' clinical information including gender, age, tumour location and HIV status was obtained from the original histopathology request forms. A morphological description was assessed using H&E-stained slides, with diagnoses confirmed by immunohistochemistry, and EBV detection performed via in situ hybridisation. RESULTS During the 20 years period investigated, 113 PBL were found. Males outnumbered females (M:F ratio of 3:1), with a median age of 41 years (range 8-62). The gingiva (50 cases or 44.2%) and the palate (23 cases or 20.4%) were the most affected sites. All cases with available information were HIV positive. The tumours were composed of a diffuse proliferation of immunoblasts or plasmablasts in all cases. A starry-sky pattern, tissue necrosis, cellular pleomorphism and mitotic figures were common microscopic findings. IHC for CD3 and CD20 were negative in all cases, while positivity for CD38, CD138 and MUM1 was observed in 70.2%, 79.2% and 98.9%, respectively. EBV was present in 100% of the cases. CONCLUSION PBL is a frequent diagnosis in South Africa, due to the country's HIV burden, where it usually affects the oral cavity and is always associated with EBV infection.

Abstract
CONTEXT.— The World Health Organization Classification of Tumours: Digestive System Tumors, 5th edition, was published in 2019 and shows several impactful changes as compared with the 4th edition published in 2010. Changes include a revised nomenclature of serrated lesions and revamping the classification of neuroendocrine neoplasms. Appendiceal goblet cell adenocarcinoma is heavily revised, and intrahepatic cholangiocarcinoma is split into 2 subtypes. New subtypes of colorectal carcinoma and hepatocellular carcinoma are described. Precursor lesions are emphasized with their own entries, and both dysplastic and invasive lesions are generally recommended to be graded using a 2-tier system. Hematolymphoid tumors, mesenchymal tumors, and genetic tumor syndromes each have their own sections in the 5th edition. New hematolymphoid lesions include monomorphic epitheliotropic intestinal T-cell lymphoma; duodenal-type follicular lymphoma; intestinal T-cell lymphoma, not otherwise specified; and indolent T-cell lymphoproliferative disorder of the gastrointestinal tract. This paper will provide an in-depth look at the changes in the 5th edition as compared with the 4th edition. OBJECTIVE.— To provide a comprehensive, in-depth update on the World Health Organization classification of digestive tumors, including changes to nomenclature, updated diagnostic criteria, and newly described entities. DATA SOURCES.— The 5th edition of the World Health Organization Classification of Tumours: Digestive System Tumours, as well as the 4th edition. CONCLUSIONS.— The World Health Organization has made many key changes in its newest update on tumors of the digestive system. Pathologists should be aware of these changes and incorporate them into their practice as able or necessary.

Abstract
Plasmablastic lymphoma (PBL) is an aggressive B-cell lymphoma with an immunoblastic/large cell morphology and plasmacytic differentiation. The differential diagnosis with Burkitt lymphoma (BL), plasma cell myeloma (PCM) and some variants of diffuse large B-cell lymphoma (DLBCL) may be challenging due to the overlapping morphological, genetic and immunophenotypic features. Furthermore, the genomic landscape in PBL is not well known. To characterize the genetic and molecular heterogeneity of these tumors, we investigated thirty-four PBL using an integrated approach, including fluorescence in situ hybridization, targeted sequencing of 94 B-cell lymphoma related genes, and copy-number arrays. PBL were characterized by high genetic complexity including MYC translocations (87%), gains of 1q21.1-q44, trisomy 7, 8q23.2-q24.21, 11p13-p11.2, 11q14.2-q25, 12p and 19p13.3-p13.13, losses of 1p33, 1p31.1-p22.3, 13q and 17p13.3-p11.2, and recurrent mutations of STAT3 (37%), NRAS and TP53 (33%), MYC and EP300 (19%) and CARD11, SOCS1 and TET2 (11%). Pathway enrichment analysis suggested a cooperative action between MYC alterations and MAPK (49%) and JAK-STAT (40%) signaling pathways. Of note, EBVnegative PBL cases had higher mutational and copy-number load and more frequent TP53, CARD11 and MYC mutations, whereas EBV-positive PBL tended to have more mutations affecting the JAK-STAT pathway. In conclusion, these findings further unravel the distinctive molecular heterogeneity of PBL identifying novel molecular targets and the different genetic profile of these tumors related to EBV infection.

Abstract
AIMS We utilised chromogenic and fluorescence in-situ hybridisation (CISH and FISH) to evaluate MYC gene copy numbers and rearrangements within HIV-associated plasmablastic lymphomas (PBLs). Thereafter, clinicopathological features were explored retrospectively. METHODS AND RESULTS Sixty-seven (n = 67) patients were included and the HIV seropositive status was confirmed in 98% (63 of 64) with a median viral load of 55 587 (IQR 273 582) copies/ml and median CD4 count of 170 (IQR 249) cells/µl. The mean age was 41 ± 10.1 years and females comprised 54%. PBL was documented predominantly at extra-oronasal topographic regions. Starry-sky (SS) appearance was evident in 33% in association with monomorphic morphology (P-value 0.02). c-MYC protein was expressed in 81% and latent EBV infection was detected in 90%. EBER ISH-positive status and MYC rearrangement occurred in 67% of HIV PBL. MYC aberrations included MYC rearrangement (70%), low-level increase in MYC gene copy numbers (43%), concurrent MYC rearrangement and increased MYC gene copy numbers (49%) as well as low-level chromosome 8 polysomy (6%). MYC aberrations in HIV PBLs were significantly associated with SS appearance (P -0.01), monomorphic morphology (P - 0.03), c-MYC protein expression ≥40% (P - 0.03) and mortality (P - 0.03). There was advanced stage (Ann Arbor III/IV) at presentation (77%) and the median overall survival for HIV PBL was 75 days (95% CI 14-136). CONCLUSION Majority of the HIV-associated PBL tumours harbour MYC aberrations. Due to the persistently inferior survival outcome of HIV-associated PBL in the era of antiviral treatment, targeted and/or intensified therapy of oncogenic MYC may need to be explored in future.

Abstract
The gastrointestinal (GI) tract is home to a significant portion of the immune system, which interacts daily with the antigenic milieu of its contents. Therefore, the presence of white blood cells within the walls of the GI tract upon histologic examination is a familiar sight on GI biopsies-both in health and disease. The GI tract is the most common site of extranodal lymphomas, most of which are B-cell neoplasms. Here, we review common and uncommon B-cell neoplasms of the GI tract - extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma), mantle cell lymphoma, duodenal-type follicular lymphoma, diffuse large B-cell lymphoma, plasmablastic lymphoma, EBV-positive mucocutaneous ulcer, and post-transplant lymphoproliferative disorders - with special focus on literature published during the past five years. Along with the other articles in this edition of Seminars in Diagnostic Pathology, it is the authors' hope that this review proves to be a useful resource in the workup of the array of hematopoietic processes that can involve the GI tract.

Abstract
Lymphoproliferative processes which occur in the gastrointestinal tract range from benign reactive processes such as follicular hyperplasia (rectal tonsil) to high grade malignant lymphomas and histiocytic sarcoma. The WHO Classification of Tumors: Digestive System Tumors, 5th Edition was published in 2019 and shows several impactful changes as compared to the 4th Edition published in 2010. WHO Classification of Tumors of Hematopoietic and Lymphoid Tissues 2017 also included detailed changes in hematopoietic neoplasms within the gastrointestinal tract. New entities or renamed hematolymphoid lesions include monomorphic epitheliotropic intestinal T-cell lymphoma, duodenal-type follicular lymphoma, intestinal T-cell lymphoma, NOS and indolent T-cell lymphoproliferative disorder of the gastrointestinal tract. A brief overview of WHO classification of digestive tumors and WHO classification of tumors of hematopoietic and lymphoid tissue is discussed focusing on the changes in the most recent WHO texts. In depth discussions will be presented in other papers in this series.

Abstract
OBJECTIVES Plasma cell myeloma (PCM) involving skin is rare and occurs in 1% to 4% of patients with PCM. We evaluated the clinicopathologic features, cytogenetic findings and clinical follow-up in a series of PCM cases with cutaneous involvement. METHODS Cases of PCM with cutaneous involvement were retrospectively reviewed with clinical data. RESULTS Skin involvement in PCM occurred in older individuals (mean, 75 years) and was more frequent in men (7/10 patients). All cases showed bone marrow involvement preceding the cutaneous lesions. Histopathologically, the infiltrate was plasmacytic (n = 5) or primitive or plasmablastic (n = 4), and 1 case showed predominantly lymphoplasmacytic features with cyclin D1 immunoreactivity and CCND1 gene rearrangement. Concurrent amyloid deposition was seen in one biopsy, and another case demonstrated coexisting squamous cell carcinoma. The most common immunophenotype was CD138+, CD20-, and CD56+ with light chain restriction. Cytogenetic analysis (available for 7 cases) showed multiple hyperdiploid abnormalities. Follow-up was available for 8 cases (mean, 42 months; range, 11-156 months) and showed short-term disease-related death in 7 of 8 patients. CONCLUSIONS Cutaneous involvement in PCM demonstrates a diverse cytomorphologic spectrum with plasmacytic, plasmablastic, or lymphoplasmacytic features and may show concurrent amyloid deposition or neoplasms such as squamous cell carcinoma. Cutaneous involvement typically occurs late in the course of the disease and likely portends poor outcome.

Abstract
Plasmablastic lymphoma (PBL) is a rare aggressive subtype of mature large B cell lymphoma involving almost exclusively the extranodal regions particularly the oral cavity, frequently described in immunocompromised patients. PBL is characterized histologically by diffuse proliferation of large neoplastic cells resembling B immunoblasts or plasmablasts. The diagnosis of PBL can be difficult due to its ambiguous histopathological features mimicking most large cell lymphomas and lacking a distinctive immunophenotypic pattern. They typically lack expression of CD20 and CD79a but may express plasma cell marker, CD138. Aberrant immunoexpression of CD3, a T-cell marker in PBL in the absence of other B-cell markers is exceptionally rare, may potentially lead to incorrect interpretation. Herein, we report a case series of CD3-positive PBL of oral cavity in two individuals, which were initially misdiagnosed as high-grade T-cell lymphomas including extranodal NK/T-cell lymphoma, nasal type. Useful distinguishing clinical settings, histomorphological features, immunohistochemistry and molecular expression profiles of PBL are discussed.

Abstract
Plasmablastic lymphoma is a rapidly progressive CD20 negative large cell non-Hodgkin lymphoma with poor outcome. It occurs mostly in immunocompromised individuals and has a predilection for extranodal sites. They need to be differentiated from other entities sharing similar morphological features like poorly differentiated carcinoma, Burkitt's lymphoma, Alk positive large B cell lymphoma, Diffuse large B cell lymphoma, and anaplastic myeloma. EBV negativity in recipients, type, intensity, and duration of immunosuppressives used are certain risk factors in development of posttransplant lymphoproliferative disorders. High index of suspicion can help clinch the diagnosis early and prevent catastrophic consequences. Our renal transplant recipient presented with complaints of pain abdomen and malena for which he underwent exploratory laparotomy. Diagnosis was established on histopathology and timely treatment initiated reverted the disease.

Abstract
Plasmablastic lymphoma (PBL) is an aggressive high-grade B cell lymphoma, considered a variant of diffuse large B cell lymphoma with approximately 75% mortality within 6-7 months. We describe an unusual case of PBL arising as a maxillary mass in an HIV-negative, nontransplanted 78-year-old female. Histologic examination revealed a diffuse infiltrate of anaplastic appearing cells exhibiting plasmablastic morphology with an adjacent contiguous infiltrate of mature appearing plasma cells. The PBL and mature plasma cell components both demonstrated an immunophenotype of CD20(-), CD38(+), and CD138(+). The two populations differed by the PBL featuring a high proliferation rate by Ki-67 (~95%) with coexpression of both c-MYC and EBV, while the mature plasma cell component featured a low proliferation rate by Ki-67 (~5%) without coexpression of c-MYC or EBV. Kappa/lambda staining demonstrated lambda light chain restriction involving the PBL, while the mature plasma cell infiltrate revealed kappa light chain restriction. Our findings describe the rare association of PBL with a synchronous distinct population of mature plasma cells exhibiting opposite light chain restriction.

Abstract
Plasmablastic lymphoma (PBL) is a rare and clinically aggressive neoplasm that typically occurs in immunocompromised individuals, including those infected with human immunodeficiency virus (HIV) and solid organ allograft recipients. Most prior studies have focused on delineating the clinico-pathological features and genetic attributes of HIVrelated PBL, in which MYC deregulation, Epstein-Barr virus (EBV) infection and, more recently, mutations in JAK/STAT, MAP kinase, and NOTCH pathway genes have been implicated in disease pathogenesis. The phenotypic spectrum of post-transplant (PT)-PBL is not well characterized and data on underlying genetic alterations are limited. This led us to perform comprehensive histopathological and immunophenotypic evaluation and targeted sequencing of 18 samples from 11 patients (8 males, 3 females; age range, 12-76 years) with PT-PBL; eight de novo and three preceded by other types of post-transplant lymphoproliferative disorders. Post-transplant PBL displayed morphological and immunophenotypic heterogeneity and some features overlapped those of plasmablastic myeloma. Six (55%) cases were EBV positive and five (45%) showed MYC rearrangement by fluorescence in situ hybridization. Recurrent mutations in epigenetic regulators (KMT2/MLL family, TET2) and DNA damage repair and response (TP53, mismatch repair genes, FANCA, ATRX), MAP kinase (KRAS, NRAS, HRAS, BRAF), JAK/STAT (STAT3, STAT6, SOCS1), NOTCH (NOTCH1, NOTCH3, SPEN), and immune surveillance (FAS, CD58) pathway genes were observed, with the mutational profiles of EBV+ and EBV– cases exhibiting both similarities and differences. Clinical outcomes also varied, with survival ranging from 0-15.9 years after diagnosis. Besides uncovering the biological heterogeneity of PT-PBL, our study highlights similarities and distinctions between PT-PBL and PBL occurring in other settings and reveals potentially targetable oncogenic pathways in subsets of the disease.

Abstract
Plasmablastic lymphoma (PBL) is a rare aggressive lymphoma. Although it was first described in HIV- (human immunodeficiency virus-) infected patients, PBL has been diagnosed in patients with other immunodeficiencies as well as in immunocompetent patients. PBL immunohistochemically expresses plasmacytic markers and lacks pan B-cell markers. The cells of origin of PBL are considered to be plasmablasts. MYC gene rearrangement and MYC overexpression are frequently found in PBL, but the pathogenesis of PBL is yet to be elucidated. Here, we report a case of composite lymphoma of PBL and diffuse large B-cell lymphoma (DLBCL); that is, PBL in the urinary bladder and DLBCL in the nasal cavity occurred simultaneously. We extracted DNA from the two lymphomas for polymerase chain reaction and sequenced the amplified immunoglobulin heavy variable genes and the complementarity-determining region- (CDR-) 3. The sequence of the CDR3 region of both tumors matched. MYC rearrangement was found in the bladder tumor but not in the nasal tumor. The patient was treated with R-CHOP (rituximab, cyclophosphamide, vincristine, doxorubicin, and prednisone), and durable remission had been obtained. The results of the DNA analysis indicated that both PBL and DLBCL emerged from common postgerminal B cells. This case may help to elucidate the pathogenesis of PBL.

Abstract
Herein we analyzed survival outcomes in chemotherapy-treated patients with plasmablastic lymphoma (PBL) diagnosed between 2010 to 2016 (n = 248). Data was acquired from the Surveillance, Epidemiology, and End Results (SEER) 18 registries database (April 2019 release based on November 2018 submission). The majority of patients were male (81.9%) and younger than 60 years (71.0%). Oral and gastrointestinal (GI) sites were the most frequent primary extranodal locations (23% and 19.4%, respectively). Oral primary location was inversely associated with presence of B symptoms and advanced Ann-Arbor stage. The 3-year and 5-year overall survival (OS) rates of treated PBL patients were 54% (95% CI: 46.5%-60.8%) and 52.8% (95% CI: 45.2%-59.8%). Three-year conditional survival for 2-year and 3-year survivors were 90.3% and 97.8%, overlapping the survival of a general population matched by age, sex and calendar year. In a multivariable analysis, oral primary location was associated with not only better OS (HR 0.43; 95% CI: 0.21-0.88, P = .021) but also better lymphoma-specific survival (LSS) (SHR 0.36; 95% CI: 0.15-0.86, P = .022); age ≥60 years was associated with shorter LSS (SHR 1.73; 95% CI: 1.02-2.96, P = .043). Seven registries granted access to HIV status (n = 93) where HIV infection was detected in 52.7% of cases. The HIV status did not affect survival outcomes in unadjusted and adjusted analyses. We identified clinical characteristics associated with survival and showed that treated PBL patients may achieve long-term survival.

Abstract
OBJECTIVES Plasmablastic lymphoma (PBL) is a clinically aggressive lymphoma which has a predilection for extranodal sites and is frequently HIV-associated. The incidence of non-Hodgkin lymphoma is thought to be reduced by widescale antiretroviral therapy (ART) coverage, but the literature is sparse as regards the impact of ART on the incidence of PBL and its outcomes in South Africa (SA). This study aimed to compare factors of interest in cases of PBL diagnosed before and after the widespread availability of ART in Johannesburg, SA. METHODS All cases of PBL diagnosed in the state sector hospitals of Johannesburg in 2007 and 2017 (before and after the widespread availability of ART, respectively) were extracted from the laboratory information system, and factors of interest compared. RESULTS The majority (> 95%) of cases of PBL were seen among people with HIV infection (PWH) at both time-points, and the proportion of patients on ART and with virological suppression (VS) increased significantly in 2017. However, the number of cases of PBL did not differ significantly between the two years assessed, comprising 46/397 (11.6%) and 53/582 (9.6%) of all lymphomas in 2007 and 2017, respectively (P = 0.23). Ongoing risk for PBL among PWH with virological control and immunological recovery was evident in 2017, as 18.9% of the patients had both VS and CD4 counts > 200 cells/μL at diagnosis. Inferior survival times were associated with elevated lactate dehydrogenase (LDH) levels and Epstein Barr virus (EBV) negativity, but were not influenced by the presence of AIDS, ART or VS. EBV negativity was significantly associated with VS, and appeared to flag a particularly aggressive form of the disease. CONCLUSIONS Widescale ART coverage has not reduced the incidence of PBL in Johannesburg, and an ongoing risk for this disease among PWH with adequate virological control and immunological recovery persists.

Abstract
Plasmablastic lymphoma (PBL) is a rare type of non-Hodgkin lymphoma frequently found in the context of immunosuppression and infection with human immunodeficiency virus (HIV) and/or Epstein-Barr virus (EBV). A 33-year-old immunocompetent male presented with recurrent episodes of epistaxis and a growing intranasal mass. Excisional biopsy of the mass revealed an immunohistochemical profile diagnostic of PBL. Upon completion of chemoradiation, he underwent a transnasal endoscopic mucosal flap tissue rearrangement to restore patency for both functional and surveillance purposes. There was no endoscopic evidence of residual or recurrent disease. However, 8 months later, he was found to have a relapse involving the skin. The nasal cavity is one of the most common sites affected by PBL. Involvement of the nasal cavity may present with symptoms of persistent epistaxis accompanied by an enlarging mass. A plasmablastic immunophenotype in combination with HIV or EBV positivity can aid diagnosis.

Abstract
Background Plasmablastic lymphoma (PBL) is an aggressive subtype of mature B-cell non-Hodgkin lymphoma. Given its rarity, there remains a lack of clinicopathological data to guide its management, particularly on Asian patients. Methods We conducted a retrospective chart review of 10 patients diagnosed with PBL at the National Cancer Centre Singapore and performed a literature review of similar studies on Asian cohorts. Results Most patients were male (n = 9), with median age at diagnosis of 55 years (range, 33 - 91 years). Seven (70%) patients were considered to be immunocompromised. In the overall cohort, the median overall survival (OS) was 19.4 months with 5-year survival estimates given at 60% and 36% for OS and progression-free survival (PFS), respectively. At diagnosis, patients with HIV/AIDS (n = 5) were younger compared to others (median, 43 vs. 61 years; P = 0.0278), had greater number of nodal site involvement (median, 6 vs. 0; P = 0.0333), and higher international prognostic index (IPI) scores (P = 0.034 for trend). Amongst different chemotherapy used, etoposide, prednisone, vincristine, cyclophosphamide and doxorubicin (EPOCH)-based regimens (n = 6) elicited prominent complete response rates (83%) and led to durable responses even in the setting of advanced stage, high-risk IPI score and immunodeficiency. Conclusions In conclusion, our study describes the features of PBL in an Asian cohort and highlights disease features unique to HIV-associated PBL.

Abstract
BACKGROUND. Plasmablastic lymphoma (PBL) is an aggressive B-cell lymphoma that is characterized by the expression of plasma cell antigens and loss of pan B-cell antigens. The neoplasm is extensively reported in the oral cavity and anorectal region but rarely in the gastrointestinal tract, where only isolated case reports and small case series have been reported. In the current study, morphologic, immunohistochemical, and molecular features of 17 cases of gastrointestinal tract PBL were reviewed. METHODS. Ten-year retrospective study that reappraised the histomorphological and immunophenotypical profiles of HIV-associated PBLs in the gastrointestinal tract. RESULTS. The mean age of the study patients was 41 years with a 3:1 ratio of males to females. The most common site of tumor origin was the small intestine (42%), followed by the stomach (29%) and the colon (29%). Majority of the cases showed a predominant diffuse (82%) growth pattern. Immunoblasts and plasmablasts were observed in all cases. Plasmacytic differentiation was seen in 5 (29%) cases. Additional observations not previously described or emphasized in literature includes pseudo-alveolar growth pattern, centroblast-predominance, multinucleated giant cells, and clear cell change. Immunohistochemistry revealed absence of pan B-cell antigens and expression of plasma cell antigens in all cases. Epstein-Barr virus-encoded RNA was expressed in 53% of the cases. CONCLUSIONS. This study highlights the spectrum of histopathological features seen in gastrointestinal tract PBLs. Awareness of this entity and its histopathological features in the gastrointestinal tract is essential for making a timely and accurate diagnosis and improving patient outcomes.

Abstract
Objective: To evaluate the clinicopathologic characteristics and outcomes of HIV-negative plasmablastic lymphoma (PBL) . Methods: Medical records of 15 patients diagnosed with HIV-negative PBL in Changhai Hospital between January 2013 and August 2019 were reviewed, and clinicopathologic characteristics and outcomes were analyzed. Results: Median age was 59 years (range: 17-69) . All patients had extranodal involvement. According to the Cotswolds-modified Ann Arbor staging system, 1 (6.7%) , 2 (13.3%) , 3 (20.0%) , and 9 (60.0%) patients were classified as at Ⅰ,Ⅱ,Ⅲ and Ⅳ, respectively. Plasmablast and immunoblast proliferations were typical manifestations of PBL. Immunohistochemical staining showed tumor cells were diffusely positive for plasma cell markers CD38, CD138, and Mum-1, while negative for B cell markers CD20, CD10, PAX-5, and BCL-6. Median Ki-67 index was 80% (70%-90%) . Epstein-Barr virus-encoded RNA (EBER) expression was detected in 3 patients, and 1 of them was positive. All patients received chemotherapy, 80% combined with bortezomib as the first line, and responses were observed in 8 patients (6 complete and 2 partial responses) . Median progression-free survival (PFS) and overall survival (OS) were 6.8 (95% CI 2.5-11.1) months and 17.9 (95% CI 5.6-30.2) months, the 3-year PFS and OS rates were 21.2% (95% CI 1.4%-56.8%) and 38.5% (95% CI 12.0%-65.0%) , respectively. Conclusion: HIV-negative PBL with high invasiveness is extremely prone to extranodal involvement and most patients were at the advanced stage. Patients receiving an intensive therapy combined with bortezomib and bridged autologous stem cell transplantation may improve long-time survival.

Abstract
Plasmablastic lymphoma (PBL) is an aggressive lymphoma often seen in immunodeficient patients. It can be a diagnostic challenge given its high-grade appearance and lack of staining for traditional B-cell markers. We present an interesting case of a 65-year-old African-American female who presented to the emergency department (ED) with complaints of progressively worsening weakness, fatigue, and dizziness for one month, and dark-colored urine for three days. The patient's medical history was remarkable for a renal and pancreatic transplant in 2008.

Abstract
Plasmablastic lymphoma (PBL) is a CD20-negative large B-cell lymphoma with a plasmacytic phenotype and a dismal prognosis, which has been defined as a distinct entity only in the 2008 WHO Classification of Haematopoietic and Lymphoid Tissue and confirmed in the 2017 Edition. Current knowledge of the biological, clinical and prognostic features of PBL is mostly limited, resulting in diagnostic issues, as well as in lack of standard of care and effective therapeutic options. PBL commonly affects the oral cavity of HIV-positive individuals, however the gastrointestinal (GI) tract is the most common extraoral site, and in this location most patients are HIV-negative. In this review, we focus on the clinical, morphological and prognostic features of PBL arising in the GI tract, in order to improve knowledge on this rare, but aggressive disease.

Abstract
Background Human immunodeficiency virus (HIV)-negative plasmablastic lymphoma (PBL) is a rare entity of diffuse large B-cell lymphoma (DLBCL). The clinicopathological features of and optimal treatment for HIV-negative PBL remain largely unknown. Methods To gain insight into this distinct lymphoma, we summarized the clinicopathologic characteristics of 8 unpublished HIV-negative PBLs and performed a comprehensive review of 394 published cases. Results Of the 8 unpublished PBLs, the median patient age was 53.0 years. Four patients presented with stage IV disease. All 8 patients showed a plasma cell-like immunophenotype. Of the six patients who received anthracycline-based chemotherapy, including two who received bortezomib, three patients achieved a continuous complete response, two patients died due to disease progression, and one patient was lost to follow-up. The other two patients achieved continuous complete response after receiving chemotherapy combined with radiotherapy and surgery. Of the 402 patients, the majority were male, with a mean age of 58.0 years. EBV infection was detected in 55.7% of the patients. The median survival times of the patients who received CHOP or CHOP-like regimens and intensive regimens were not reached and 23.0 months, respectively, and the intensive regimen did not improve the survival outcome (P=0.981). Multivariate analysis showed that EBER remained the only independent factor affecting overall survival (OS). Conclusion HIV-negative PBL is a distinct entity with a predilection for elderly and immunosuppressed individuals. Intensive chemotherapy had no apparent survival benefits over the CHOP regimen in terms of OS; the prognosis of this disease is poor with current chemotherapy methods, and treatment remains a challenge.

Abstract
Plasmablastic neoplasms encompass several entities including plasmablastic lymphoma, plasmablastic plasmacytoma/multiple myeloma, primary effusion lymphoma and its extracavitary variant, anaplastic lymphoma kinase-positive large B-cell lymphoma, and Kaposi sarcoma-associated herpesvirus/human herpesvirus 8 (HHV8)-positive diffuse large B-cell lymphoma, not otherwise specified. Morphologically, the tumor cells are large with eccentrically located nuclei, prominent nucleoli, and basophilic/amphophilic cytoplasm. Immunophenotypically, the tumor cells express plasma cell-related antigens including CD38, CD138, interferon regulatory factor-4 (IRF4)/MUM1, PR domain zinc finger protein-1 (PRDM1), and/or X-box binding protein-1 (XBP1), with frequent loss of CD20. These tumors are diagnostically challenging for general pathologists due to their overlapping morphology and immunophenotype, and due to their rarity, and particularly so when clinical and radiologic information is insufficient. We also discuss HHV8-negative effusion-based lymphoma due to its overlapping features with primary effusion lymphoma. In this review, we focus on the useful diagnostic markers and pertinent molecular findings in these distinct entities and propose a practical diagnostic algorithm using anaplastic lymphoma kinase, HHV8, in situ hybridization for Epstein-Barr virus-encoded small RNA, immunoglobulin M, light chain stains, and clinicoradiologic criteria to avoid misdiagnosis. At the molecular level, MYC protein overexpression with or without MYC rearrangement and PRDM1-inactivating mutations or deletions are noted in a subset of such tumors, especially in plasmablastic lymphoma. Prognosis in these entities is dismal with conventional CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) chemotherapy. Therefore, novel target therapies, such as anti-CD30 agents, and/or immune blockade therapy, are potential treatment options in the future.

Abstract
AIMS Plasmablastic lymphoma (PBL) occurs mainly in immunocompromised individuals, usually secondary to human immunodeficiency virus (HIV) infection. It classically occurs intraorally, but has been described in extraoral locations. The aim of this study was to define the immunophenotype and Epstein-Barr virus (EBV) status in a large single-centre cohort of extraoral PBL (EPBL) in South Africa, a high-prevalence HIV setting. METHODS AND RESULTS This retrospective study of 45 EPBLs included patients' age, gender, race, HIV status, and site. Cases were reviewed histologically, and classified morphologically as pure plasmablastic or plasmablastic with plasmacytic differentiation, and assessed immunohistochemically with antibodies against CD45, CD20, CD79a, PAX5, CD138, MUM1/IRF4, BLIMP1, VS38c, Ki67, bcl-6, CD10, cyclin D1, and human herpesvirus-8, by the use of standard automated procedures. EBV was assessed by the use of chromogenic in-situ hybridisation. Tumours were assessed with a fluorescence in-situ hybridisation (FISH) MYC break-apart probe. Twenty-seven PBLs showed pure plasmablastic morphology, and 18 showed plasmacytic differentiation. The male/female ratio was 1.5:1. The anus was the favoured extraoral site (31.1%), followed by lymph nodes (15.6%). All 29 patients with known HIV status were HIV-positive. The immunohistochemical profile recapitulated that reported for oral PBLs and EPBLs in HIV-positive and HIV-negative patients. EBV was positive in 92.5% of PBLs. FISH analysis showed MYC rearrangement in 48% of cases. CONCLUSION This study showed a strong association of EPBLs with HIV and EBV infection, similarly to the previously described oral PBL. The strong EBV association together with other clinicopathological parameters and an immunohistochemical profile that includes CD45, CD20, MUM1/IRF4, CD138 and Ki67 may be used in distinguishing PBL from diffuse large B-cell lymphoma and plasma cell myeloma.

Abstract
AIMS MYC rearrangements are the main cytogenetic alterations in plasmablastic lymphoma (PBL). We aimed to investigate the relationship between MYC rearrangement and the clinicopathological features of PBL. METHODS AND RESULTS MYC rearrangements assessed in 13 unpublished single-centre PBL cases, and an additional 85 cases from the literature, with reported MYC rearrangement information individualised by patient, were reviewed. In Asia, PBL was much less commonly diagnosed in human immunodeficiency virus (HIV)-positive patients (27% versus 84%, P = 0.000), with older age (median age at diagnosis: 52 years versus 44 years, P = 0.046) and a lower EBV infection rate (56.8% versus 81.8%, P = 0.049), than in non-Asian regions. Overall, MYC rearrangements were identified in 44 of 98 (44.9%) PBL cases, and IGH was the partner in almost all available cases (30/31, 96.8%), as confirmed with a MYC-IGH fusion probe. The MYC rearrangement rate in HIV-positive cases (33/55, 60.0%) was significantly higher than that in HIV-negative cases (11/38, 28.9%, P = 0.003). Patients with MYC rearrangement showed a trend towards an inferior median survival time (9.6 months versus 15.7 months, P = 0.122) and 2-year overall survival (17% versus 32%, P = 0.238). CONCLUSIONS MYC rearrangement was frequently identified in PBL patients, and IGH was the partner gene in an overwhelming majority of MYC rearrangements. In addition, the MYC rearrangement rate was significantly higher in HIV-positive PBL patients than that in HIV-negative patients. MYC rearrangement may play an important role in the pathogenesis of HIV-positive PBL, but further studies are required to understand the underlying mechanisms.

Abstract
Plasmablastic lymphoma (PBL) is an aggressive malignancy that usually occurs in the setting of immunosuppression. The immunohistochemical profile of PBL is that of terminally differentiated B lymphocytes. CD138, CD38, and MUM1 are usually immunopositive. However, pan B-cell markers such as CD20 and PAX-5 are usually negative. MYC rearrangement is the most commonly encountered genetic alteration, with immunoglobulin (IG), especially immunoglobulin heavy (IGH) chain, being the most frequent partner. We report a case of PBL in a 48-year-old human immunodeficiency virus- (HIV-) positive male who was admitted to the hospital with signs and symptoms suspicious for tumor lysis syndrome. Bone marrow examination revealed hypercellular marrow with trilineage hypoplasia and sheets of intermediate to large neoplastic cells with basophilic vacuolated cytoplasm comprising the majority of cellular elements of the bone marrow. The neoplastic cells were negative for conventional B-cell, T-cell, plasma cell, and myeloid markers, while flow cytometric analysis revealed an abnormal CD45-dim population that was partially weakly positive for CD71 and CD79b. The diagnosis was initially thought to be a high-grade primitive hematopoietic neoplasm, possibly an acute undifferentiated leukemia. BOB-1, however, was immunopositive in the neoplastic cells, confirming its B-cell origin. MYC was positive by immunohistochemistry and break-apart FISH, as were CD45, MUM-1, and EMA immunostains. There was immunoglobulin kappa (IGK) light chain gene rearrangement by polymerase chain reaction (PCR). Additionally, Epstein–Barr virus- (EBV–) encoded small RNAs (EBER) were positive by in situ hybridization (ISH). The tumor proliferation index by Ki-67 immunostaining approached 95%. Although the tumor cells were negative for CD38 and CD138, the diagnosis of PBL was still rendered. We recommend using a broad spectrum of B-cell markers, including BOB-1 and OCT-2, in such challenging cases of B-cell lymphomas with no expression of conventional B-cell markers. We also emphasize that the negative CD38 and CD138 should not exclude PBL from the differential diagnosis.
