Abstract
DISEASE OVERVIEW Plasmablastic lymphoma (PBL) is a rare CD20-negative aggressive lymphoma with a poor prognosis under standard treatment options. Though PBL is associated with human immunodeficiency virus infection and other immunosuppressed states, it can also affect immunocompetent individuals. DIAGNOSIS The diagnosis requires a high clinical suspicion and pathological confirmation. EBER expression and MYC gene rearrangements are frequently detected. The differential diagnosis includes EBV+ diffuse large B-cell lymphoma, extracavitary primary effusion lymphoma, ALK+ DLBCL, and HHV8+ large B-cell lymphoma, among others. RISK STRATIFICATION Age ≥60 years, advanced clinical stage, and high intermediate and high International Prognostic Index scores are associated with worse survival. MANAGEMENT Combination chemotherapy regimens, such as EPOCH, are recommended. The addition of bortezomib, lenalidomide, or daratumumab might improve outcomes. Including PBL patients and their participation in prospective clinical trials is warranted.

Abstract
Non-secretory multiple myeloma (NSMM) is a rare cancer of plasma cells characterized by the absence of detectable monoclonal M protein in the blood or urine. A 57-year-old woman presented with mandibular pain but without intraoral swelling. Imaging studies revealed multiple osteolytic lesions in her mandible and pronounced root resorption of the left mandibular second molar. Biopsy results showed atypical plasmacytoid cells positive for anti-kappa, CD138, MUM1, and CD79a antibodies, but negative for anti-lambda and CD20. These results were indicative of a malignant plasma cell neoplasm. No abnormalities were revealed by free light chain assay or by serum or urine protein electrophoresis, leading to a diagnosis of NSMM. The patient began chemotherapy in conjunction with bisphosphonate therapy and achieved remission following treatment. This case underscores the critical role of dentists in the early detection and prevention of NSMM complications, as the disease can initially present in the oral cavity.

Abstract
BACKGROUND Plasmablastic Lymphoma (PBL) is a rare aggressive B-cell lymphoma that primarily affects immunocompromised individuals, including those living with HIV. Historically, survival estimates are dismal and range from 8 to 15 months. We aimed to evaluate epidemiologic characteristics, treatment patterns and survival trends on a national scale. PATIENTS AND METHODS Patients diagnosed with PBL from 2010 to 2020 were identified in the National Cancer Database (NCDB) and in the Surveillance, Epidemiology, and End Results (SEER) program. Incidence rates were calculated using SEER. Demographic features, treatment characteristics, and overall survival (OS) were identified using the NCDB. RESULTS We identified 1153 patients in the SEER database and 1822 patients in the NCDB. The incidence of PBL is 0.07 cases per 100,000 US population per year. PBL is more common in males (77%), and white patients (77%), with 50% of cases in patients with HIV. Patients who were treated with multiagent chemotherapy had a median OS of 58.6 months. On multivariate Cox regression, we found that HIV status did not have a significant impact on OS. Factors associated with worse OS included advancing age and stage. CONCLUSION We present the largest study to date on PBL. Among treated patients, we described a median OS of 58.6 months, greatly improved from previously reported estimates. We found that HIV status did not have a significant impact on OS. While OS remains poor, therapeutic advances over the last decade are promising and highlight the need for continued clinical advances aimed at improving therapeutic options for this rare lymphoma.

Abstract
Plasmablastic lymphoma (PBL) is a rare lymphoid neoplasm frequently presenting in the oral cavity. It is an aggressive type of non-Hodgkin's lymphoma that shares pathological features with plasma cell myeloma. In addition to human immunodeficiency virus (HIV), it is also associated with Epstein-Bar virus (EBV) and immunosuppression in HIV-negative patients, for example, post transplantation. Extra-oral PBL is rare and only a few case reports involving the testis have been described. Here we describe the first reported case of PBL presenting with a scrotal abscess (not involving the testes) in a patient newly diagnosed with HIV. This case highlights the rare presentation of a rare disease, the difficulties in establishing a diagnosis and the importance of a timely multidisciplinary approach to its management.

Abstract
BACKGROUND Extramedullary plasmacytoma (EMP) is a rare plasma cell malignancy, especially when the tumor originates in skeletal muscle. Plasmablastic plasmacytoma is an anaplastic round cell tumor with highly malignancy and poor prognosis. To date, there have been no reports on the transformation of skeletal muscle EMP into plasmablastic plasmacytoma. Therefore, the diagnosis, treatment, and prognosis of cases of this pathologic transformation are unclear. CASE PRESENTATION This article reports a case of an elderly male patient who presented with a painless mass in the right calf and was diagnosed with EMP by puncture pathology. Complete remission was obtained after sequential chemoradiotherapy. 6 months later, another puncture was performed due to plasmablastic plasmacytoma multiple distant metastases, and the pathology showed that EMP was transformed to plasmablastic plasmacytoma. Despite aggressive antitumor therapy, the disease continued to deteriorate, and the patient ultimately died of respiratory failure. CONCLUSION The transformation of EMP into plasmablastic plasmacytoma is very rare, and its diagnosis and treatment require the participation of both experienced pathologists and clinicians. We report this case in order to raise clinicians' awareness of the diagnosis and treatment of EMP and its transformation to plasmablastic plasmacytoma, and to avoid misdiagnosis and underdiagnosis.

Abstract
Plasmablastic lymphoma (PBL) is an aggressive large B-cell lymphoma with a terminal B-cell differentiation phenotype and is frequently associated with immunodeficiency. We aimed to investigate the clinicopathological and immunophenotypic features, genetic alterations, and mutational landscape of PBL in Taiwan. We retrospectively recruited 26 cases. Five (5/18; 28%) patients were HIV-positive and 21 (81%) presented extranodally. There were two morphological groups: one with purely monomorphic large cells (85%) and the other comprising large cells admixed with plasmacytic cells (15%). Phenotypically, the tumors expressed MYC (8/10; 80%), CD138 (20/26; 77%), and MUM1 (20/20; 100%), but not CD20 (n = 26; 0%). Fourteen (54%) cases were positive for EBV by in situ hybridization; the EBV-positive cases were more frequently HIV infected (p = 0.036), with extranodal presentation (p = 0.012) and CD79a expression (p = 0.012), but less frequent light chain restriction (p = 0.029). Using fluorescence in situ hybridization, we identified 13q14 deletion, MYC rearrangement, and CCND1 rearrangement in 74%, 30%, and 5% cases, respectively, without any cases having rearranged BCL6 or IGH::FGFR3 fusion. In the 15 cases with adequate tissue for whole exome sequencing, the most frequent recurrent mutations were STAT3 (40%), NRAS (27%), and KRAS (20%). In conclusion, most PBL cases in Taiwan were HIV-unrelated. Around half of the cases were positive for EBV, with distinct clinicopathological features. Deletion of chromosome 13q14 was frequent. The PBL cases in Taiwan showed recurrent mutations involving JAK-STAT, RAS-MAPK, epigenetic regulation, and NOTCH signaling pathways, findings similar to that from the West.

Abstract
This two-part review aims to present a current and comprehensive understanding of the diagnosis and management of plasmablastic lymphoma. The first section, as presented in this paper, reviews epidemiology, etiology, clinicopathological characteristics, differential diagnosis, prognostic variables, and the impact of plasmablastic lymphoma on specific populations. Plasmablastic lymphoma (PBL) is a rare and aggressive form of lymphoma. Previous and modern studies have demonstrated a significant association between the human immunodeficiency virus (HIV) and the development of the disease. The limited occurrence of PBL contributes to a need for a more comprehensive understanding of the molecular mechanisms involved in its etiology. Consequently, the diagnostic procedure for PBL poses a significant difficulty. Among the group of CD20-negative large B-cell lymphomas, PBL can be correctly diagnosed by identifying its exact clinical characteristics, anatomical location, and morphological characteristics. PBL cells do not express CD20 or PAX5 but possess plasmacytic differentiation markers such as CD38, CD138, MUM1/IRF4, Blimp1, and XBP1. PBL must be distinguished from other B-cell malignancies that lack the CD20 marker, including primary effusion lymphoma, anaplastic lymphoma kinase-positive large B-cell lymphoma, and large B-cell lymphoma (LBCL). This condition is frequently associated with infections caused by the Epstein-Barr virus and genetic alterations involving the MYC gene. Despite advances in our comprehension of this disease, the prognosis remains dismal, resulting in a low overall survival rate, although recent reports suggest an apparent tendency towards substantial improvement.

Abstract
OBJECTIVE To evaluate oral lymphomas' clinical manifestations and investigate whether clinical features are associated with lymphoma subtypes. STUDY DESIGN Oral lymphomas with at least 1 representative clinical image were evaluated. They were classified according to their microscopic grade (high vs low), predominant cell size (small vs medium/large), and cellular lineage (B cell vs T cell). Clinical images were described according to tumor location, number, swelling, ulcer, necrosis, telangiectasia, predominant color, and lobulation. Lymphomas affecting the palate were compared with salivary gland tumors (SGTs) affecting this location. RESULTS Data from 107 cases were included. High-grade subtypes (80.4%), with medium/large-sized cells (52.3%), and diagnosed as diffuse large B cell lymphomas (29%) predominated. High-grade lymphomas often presented as painful, ulcerative, and osteolytic diseases (P < .05). Tumors predominantly composed of medium/large-sized cells were associated with painful lesions, ulcerated, with necrosis and bone destruction (P < .05). When only palate tumors were considered, multiple and bilateral lesions, the presence of pain, ulceration, and necrosis were significantly more associated with a diagnosis of lymphoma than SGT (P < .001). CONCLUSION High-grade oral lymphomas are more associated with destructive presentation than low-grade subtypes, and bilateral lesions in the palate are more associated with a lymphoma diagnosis than SGT.

Abstract
BACKGROUND Plasmablastic lymphoma is a rare type of non-Hodgkin lymphoma that generally presents an aggressive clinical course. It is strongly associated with human immunodeficency virus (HIV) infection, and the most common site of involvement is the oral cavity. Although extraoral PBL has been reported in several places, small intestine involvement is extremely rare. CASE PRESENTATION Here, we describe an exceptionally rare case of a 24-year-old immunocompetent Asian Male patient with newly diagnosed plasmablastic lymphoma of the duodenum. The patient was admitted to our oncology facility due to the patient's clinical course, which included persistent vomiting, hematemesis, weight loss, and generalized weakness. Computed tomography of the abdomen (triphasic) of the patient showed thickness at the 2nd part of the duodenum measuring 2.6 cm in width and 16 cm in length blocking the pancreatic and common bile ducts by entering the second section of the duodenum. The biopsy specimen's pathological investigation indicated abnormal cells with plasmacytoid characteristics and a high proliferation index. The diagnosis of PBL was confirmed by immunohistochemical profiling. Supportive therapies like blood transfusions, antacids, and antiemetics were started to manage the patient's symptoms. Palliative radiation was also anticipated for the lesion site. CONCLUSIONS Duodenal involvement to the extent seen in our patient is exceptionally rare and, to the best of our knowledge, has hardly been described. The main goal of the article is to review the literature and report a case.

Abstract
Multiple myeloma (MM) is the most common primary bone-originating tumor, whereas extramedullary plasmacytoma (EMP) is a plasma cell tumor that arises outside the bone and is most commonly found in the head and neck area. Gastrointestinal and particularly gallbladder involvement is exceedingly rare, and symptoms, if any are present, are usually similar to those seen with cholelithiasis. Treatment options usually include surgical resection and/or chemotherapy. In this report, we present a rare case of a clinically unexpected plasmablastic extramedullary plasmacytoma that was found on abdominal ultrasound (US) and magnetic resonance imaging (MRI) in a 61-year-old asymptomatic patient and led him to undergo cholecystectomy. A fluorodeoxyglucose positron emission computed tomography (FDG PET-CT) that was performed due to the onset of left thigh pain also demonstrated concurrent bone plasmacytoma. The patient is currently receiving chemotherapy and is also being prepared for autologous stem cell transplantation. In this context, we further present the diagnostic, therapeutic and prognostic challenges of EMPs. Lastly, we point out the distinct features of the plasmablastic subtype and analyze its differences compared to other histologic subtypes in achieving a successful diagnosis and management.

Abstract
The family/class of the large B-cell lymphomas (LBCL) in the 5th edition of the World Health Organization (WHO) classification of haematolymphoid tumors (WHO-HAEM5) features only a few major changes as compared to the 4th edition. In most entities, there are only subtle changes, many of them only representing some minor modifications in diagnostic terms. Major changes have been made in the diffuse large B-cell lymphomas (DLBCL)/high-grade B-cell lymphomas (HGBL) associated with MYC and BCL2 and/or BCL6 rearrangements. This category now consists of MYC and BCL2 rearranged cases exclusively, while the MYC/BCL6 double hit lymphomas now constitute genetic subtypes of DLBCL, not otherwise specified (NOS) or of HGBL, NOS. Other major changes are the conceptual merger of lymphomas arising in immune-privileged sites and the description of LBCL arising in the setting of immune dysregulation/deficiency. In addition, novel findings concerning underlying biological mechanisms in the pathogenesis of the different entities are provided.

Abstract
Anaplastic myeloma (AM) is an extremely rare and aggressive histological variant of myeloma. It is characterized by extramedullary presentation in the young and has a poor prognosis. It can be a diagnostic challenge when myeloma is not suspected and even more when the immunophenotype is unexpected. We present a rare presentation of anaplastic myeloma with cardiovascular involvement. Though the patient did not have the typical clinical features of myeloma, except lytic lesion in the femur, the cardiac biopsy showed sheets of anaplastic cells, and some with multinucleation. There were also some areas with a more plasmacytoid appearance. The initial immunohistochemical panel was negative for CD3, CD20, CD138, AE1/3, and kappa. It was positive for lambda. This led to an extended panel which showed positivity for CD79a and MUM1 and negative for LMP-1, HHV-8, CD43, CD117, CD56, and CD30. Even the flow cytometry on the bone marrow showed a small population of atypical cells positive for CD38 and negative for CD138 with lambda restriction. This is an unusual case of anaplastic myeloma with cardiovascular involvement and CD138 negativity. This case highlights the need to add a panel of plasma cell markers when myeloma is suspected, and it is pertinent to read flow cytometry with caution to avoid missing atypical plasma cells which maybe CD38+/CD138-.

Abstract
Plasmablastic lymphoma (PBL) is a rare form of lymphoma in people. PBL originates from plasmablasts and usually presents with swelling/mass in the mouth/neck. A 7-year-old Mongrel dog was presented for a large oral and neck mass. Cytology and histopathology were suggestive of a round cell tumor that was suspected to be lymphoma. An immunohistochemical (IHC) stain panel showed positive for CD18, thus supporting the diagnosis of round cell tumor, but negative for T- and B-cell lymphomas, CD3, CD20, and PAX-5. Other markers including cytokeratin AE1/3 (for epithelial cell origin), CD31 (for endothelial cells), SOX10 (for melanoma), IBa-1 (for histiocytic sarcoma), and CD117 (for mast cell tumor) were all negative. MUM-1 (for plasma cell differentiation) was strongly positive and CD79a (B cell and plasma cells) was also scantly positive. Based on the histopathology and immunohistochemistry results in combination with the clinical presentation, a suspected diagnosis of PBL was made. As per available literature, this is perhaps the first highly suspected case of PBL in a dog.

Abstract
Plasmablastic lymphoma (PBL) represents a rare distinct lymphoma entity with plasmablastic morphology and plasmacytic immunophenotype that is characterized by an aggressive clinical course. Standard chemotherapeutic regimens often remain insufficient to cure affected patients. Recently, comprehensive molecular analyses of large cohorts of primary PBL samples have revealed the mutational landscape as well as the pattern of copy number alterations of this rare lymphoma subtype. Identification of recurrent aberrations affecting the JAK-STAT, RAS-RAF, NOTCH, IRF4, and MYC signaling pathways drive the molecular pathogenesis of PBL and hold great potential for novel targeted therapeutic approaches.

Abstract
Plasmablastic lymphoma (PbL) is a rare type of aggressive B-cell malignancy that has an extremely poor prognosis without chemotherapeutic treatment, requiring a high degree of suspicion for an early and accurate diagnosis. It has been classically described in patients infected with the human immunodeficiency virus (HIV). However, it accounts for only 2.6% of acquired immunodeficiency syndrome (AIDS)-related lymphomas. Extranodal involvement is most commonly seen within the oral cavity (44%). Involvement of the gastrointestinal tract (14%) is rare and can often be confused with other malignancies with plasmablastic features. We present a rare case of PbL in a 55-year-old male with HIV-AIDS (CD4 (cluster of differentiation 4) cell count of 128), who presented for evaluation of incidentally detected multiple liver masses and lytic lesions in the ribs. Further workup revealed evidence of a lesion with increased uptake in the anorectal region with fine needle aspiration (FNA) biopsy identifying the lesion as plasmablastic lymphoma.

Abstract
Epstein-Barr virus (EBV; human herpesvirus 4; HHV-4) and Kaposi sarcoma-associated herpesvirus (KSHV; human herpesvirus 8; HHV-8) are human gammaherpesviruses that have oncogenic properties. EBV is a lymphocryptovirus, whereas HHV-8/KSHV is a rhadinovirus. As lymphotropic viruses, EBV and KSHV are associated with several lymphoproliferative diseases or plasmacytic/plasmablastic neoplasms. Interestingly, these viruses can also infect epithelial cells causing carcinomas and, in the case of KSHV, endothelial cells, causing sarcoma. EBV is associated with Burkitt lymphoma, classic Hodgkin lymphoma, nasopharyngeal carcinoma, plasmablastic lymphoma, lymphomatoid granulomatosis, leiomyosarcoma, and subsets of diffuse large B-cell lymphoma, post-transplant lymphoproliferative disorder, and gastric carcinoma. KSHV is implicated in Kaposi sarcoma, primary effusion lymphoma, multicentric Castleman disease, and KSHV-positive diffuse large B-cell lymphoma. Pathogenesis by these two herpesviruses is intrinsically linked to viral proteins expressed during the lytic and latent lifecycles. This comprehensive review intends to provide an overview of the EBV and KSHV viral cycles, viral proteins that contribute to oncogenesis, and the current understanding of the pathogenesis and clinicopathology of their related neoplastic entities.

Abstract
Plasmablastic lymphoma (PBL) is a highly aggressive B cell non-Hodgkin lymphoma frequently associated with immunosuppression, particularly human immunodeficiency virus (HIV) infection. Although PBL is rare globally, South Africa has a high burden of HIV infection leading to a higher incidence of PBL in the region. Laboratory features in PBL may overlap with plasmablastic myeloma and other large B cell lymphomas with plasmablastic or immunoblastic morphology leading to diagnostic dilemmas. There are, however, pertinent distinguishing laboratory features in PBL such as a plasma cell immunophenotype with MYC overexpression, expression of Epstein-Barr virus-encoded small RNAs and lack of anaplastic lymphoma kinase (ALK) expression. This review aims to provide a summary of current knowledge in PBL, focusing on the epidemiology, pathophysiology, laboratory diagnosis and clinical management.

Abstract
Plasmablastic lymphoma (PBL) is a rare and aggressive form of large B-cell lymphoma (LBCL) most commonly seen in the setting of chronic immunosuppression or autoimmune disease. The prognosis is poor and CHOP-like regimens often fail to produce durable remission; therefore, there is no established standard of care treatment. However, PBL demonstrates substantial morphologic and immunophenotypic overlap with multiple myeloma (MM), suggesting that MM therapeutics might prove useful in treating PBL. We studied the effects of treatment using the first-in-class monoclonal antibody directed against CD38, daratumumab, in combination with chemotherapy in seven patients with advanced-stage LBCL with plasmablastic features. Treatment was safe and well-tolerated. Among six evaluable patients, six patients had complete response after treatment, and four patients who met strict WHO criteria for PBL had durable response (12-31 months and ongoing).

Abstract
AIMS Epstein-Barr virus (EBV) is causally associated with many hematolymphoid malignancies. This laboratory-based study aimed to establish the prevalence of EBV in plasma cell neoplasms in a large South African cohort and to determine whether there is any correlation between EBV-positivity and human immunodeficiency virus (HIV) status in patients with plasma cell neoplasms, including plasma cell myeloma and plasmacytoma (solitary plasmacytoma of bone and extraosseous plasmacytoma). METHODS This single-institution retrospective study included all patients with a histopathologic diagnosis of plasma cell neoplasm between 2003 and 2020. EBV-expression in the plasma cell neoplasms was assessed by EBV-encoded RNA (EBER) in situ hybridization (ISH) and correlated with HIV status. HIV status was determined by retrieving prior serologic results. Formalin-fixed paraffin-embedded tissue from HIV-unknown patients underwent HIV-1 p24 antibody testing. RESULTS Sixteen of 89 plasma cell neoplasms (18%) were EBV-positive. There was a significant correlation between EBV and HIV infection in plasma cell neoplasms, with 6/10 tumors from HIV positive patients showing EBV-positivity in tumor cells. The EBV-positive cohort was significantly younger than the EBV-negative group. CONCLUSION EBV-positivity in plasma cell neoplasms in this study is higher than previously reported. The significant occurrence of EBV in plasma cell neoplasms from HIV-positive patients suggests a co-carcinogenic relationship between the two viruses.

Abstract
Plasmablastic lymphoma is a rare subtype of large B-cell lymphoma characterised by an aggressive clinical course with frequent relapses and refractoriness to chemotherapy. It is usually associated with HIV, however, it can also be seen in immunocompetent patients. It has distinct pathological characteristics, such as plasmablastic morphology and lack of CD20 expression. These characteristics pose a clinical and pathological challenge. There is no standard of care established in this entity. In this case report, we described a novel bortezomib-based plasma cell targeted regimen in a HIV-negative patient refractory to chemotherapy.

Abstract
Characterized by an aggressive course with a poor overall survival due to treatment refractoriness, plasmablastic lymphoma (PBL) is a rare variant of diffuse large cell B cell lymphoma. Gorham’s lymphangiomatosis or Gorham–Stout disease (GSD) is a rare skeletal condition of unknown etiology characterized by progressive bone loss and nonmalignant proliferation of vascular and lymphatic channels within the affected bone. Neither disease has a standard of care. We present a 23-year-old HIV-negative woman with GSD, managed medically with octreotide and sirolimus, who developed PBL. After progressing on V-EPOCH (bortezomib, etoposide, vincristine, cyclophosphamide, doxorubicin, and prednisone), she was treated with daratumumab, lenalidomide, and dexamethasone (DRD) therapy and achieved complete remission after two cycles with progression after eight cycles. This is a report of treatment of PBL with DRD therapy. Clinical investigations of the DRD regimen in PBL in conjunction with other agents to improve both depth and durability of response are warranted.

Abstract
Plasmablastic myeloma (PBM) is a blastic morphologic variant of plasma cell myeloma with less favorable prognosis than those with non-blastic morphology. PBM is rare, without clear-cut definition and detailed clinicopathologic features in the literature. PBM may mimic plasmablastic lymphoma (PBL) as they share nearly identical morphology and immunophenotype. Using the criteria of ≥ 30% plasmablasts in tissue sections, we retrospectively recruited PBM cases and analyzed their clinical, imaging, and pathologic findings, with emphasis on extramedullary involvement. We performed immunohistochemistry, in situ hybridization for Epstein-Barr virus (EBER), and fluorescence in situ hybridization (FISH) for lymphoma- and myeloma-associated genetic alterations. Of the 25 recruited cases, 15 (60%) had extramedullary involvement, which occurred as initial presentation in nine cases. The most common extramedullary sites were soft tissue and/or skin (10/15, 67%), followed by pleural effusion, the lungs, and lymph nodes. Immunohistochemically, tumor cells expressed MYC (74%; 17/23), CD56 (56%; 14/25), and cyclin D1 (16%; 4/25), while CD117 was all negative (n = 25). Of the 20 cases stained with p53, four (20%) cases were diffusely positive, and the remaining 16 cases showed a heterogeneous pattern. EBER was negative in all 24 cases examined. Of the 13 cases examined with FISH, the genetic aberrations identified included del(13q14)(92%; 12/13), gain of chromosome 1q (90%; 9/10), loss of chromosome 1p (60%; 6/10), IGH-FGFR3 reciprocal translocation (23%; 3/13), rearranged MYC (15%; 2/13), and rearranged CCND1 (8%; 1/13), while there were no cases with TP53 deletion (n = 10) or rearrangement of BCL2 (n = 13) or BCL6 (n = 13). The prognosis was dismal regardless of the presence or absence of extramedullary involvement. In conclusion, PBM in Taiwan frequently presented as extramedullary and extranodal lesions, particularly in soft tissue and/or skin, mimicking PBL. FISH for targeted genetic alterations such as del(13q14), gain of chromosome 1q, loss of chromosome 1p, and IGH-FGFR3 might be helpful for the differential diagnoses. Larger studies are warranted to investigate the genetic alterations between PBM and PBL.

Abstract
A woman in her 80s reported of generalised pruritus, which was treated with phototherapy and steroid administration. Two months after onset, lymph node biopsy revealed CD4+ angioimmunoblastic T-cell lymphoma with systemic superficial nodal involvement. Intractable prurigo was judged as T-cell lymphoma related. After effective chemotherapy (7 months later), skin nodules appeared multifocally, including on the lip, thumb and lower leg. The biopsied infiltrative lesion on the right lower leg microscopically revealed subcutaneous growth of atypical plasmablasts with nearly 100% Ki-67 labelling and Epstein-Barr virus (EBV)-encoded small nuclear RNA positivity. Plasmablastic lymphoma (CD45/CD19/CD38/CD138/MUM1+, CD20/CD79a/PAX5-) was suspected. Immunoglobulin light-chain restriction and nuclear expression of c-myc protein were undetectable, and the ulcers were spontaneously epithelialised by the cessation of steroid administration. After 10 months, non-progressive prurigos persisted on the extremities, but without regrowth of nodal T-cell lymphoma and cutaneous lymphoproliferative lesion. Reactive nature of the EBV-induced mucocutaneous plasmablastic growth (EBV-positive mucocutaneous ulcer, plasmablastic type) is discussed.

Abstract
OBJECTIVE To describe the clinical profile and outcome of patients with HIV-associated plasmablastic lymphoma (PBL) treated with cyclophosphamide, doxorubicin, oncovin, prednisone (CHOP) chemotherapy in a tertiary hospital in KwaZulu-Natal, South Africa. METHODS This 12-year retrospective clinical chart review, from 2006 to 2018, of patients with PBL treated with CHOP chemotherapy describes their clinical presentation, complete response (CR), progression-free survival (PFS) and disease-free survival (DFS). Response to salvage chemotherapy was also assessed, as was the overall survival (OS). RESULTS Of 26 patients included in the study, PBL was the presenting manifestation of underlying HIV infection in 58% (n = 15). The median age was 35 years (range 13-49), and 62% (n = 16) were males. The median CD4 count was 285 cells/µL (range 45-863). All patients had extranodal disease, with 4% having bone marrow involvement (n = 1) and > 60% presenting with advanced stage and high-risk PBL. Central nervous system (CNS) involvement was present in 15% (n = 4). A CR was attained in 46% (n = 12). The median DFS was 23.5 months (range 5-91 months), with an overall 2-year survival of 42% (n = 11). CONCLUSIONS Patients with PBL had a low CR with CHOP chemotherapy and poor OS. Use of alternative chemotherapy regimens needs to be investigated to optimally manage this aggressive lymphoma. The surprisingly low incidence of marrow involvement is the focus of ongoing local research.

Abstract
Plasmablastic lymphoma (PBL) represents a clinically heterogeneous subtype of aggressive B-cell non-Hodgkin lymphoma. Targeted-sequencing studies and a single-center whole-exome sequencing (WES) study in HIV-positive patients recently revealed several genes associated with PBL pathogenesis; however, the global mutational landscape and transcriptional profile of PBL remain elusive. To inform on disease-associated mutational drivers, mutational patterns, and perturbed pathways in HIV-positive and HIV-negative PBL, we performed WES and transcriptome sequencing (RNA-sequencing) of 33 PBL tumors. Integrative analysis of somatic mutations and gene expression profiles was performed to acquire insights into the divergent genotype-phenotype correlation in Epstein-Barr virus-positive (EBV+) and EBV- PBL. We describe a significant accumulation of mutations in the JAK signal transducer and transcription activator (OSMR, STAT3, PIM1, and SOCS1), as well as receptor tyrosine-kinase RAS (ERBB3, NRAS, PDGFRB, and NTRK) pathways. We provide further evidence of frequent perturbances of NF-κB signaling (NFKB2 and BTK). Induced pathways, identified by RNA-sequencing, closely resemble the mutational profile regarding alterations accentuated in interleukin-6/JAK/STAT signaling, NF-κB activity, and MYC signaling. Moreover, class I major histocompatibility complex-mediated antigen processing and cell cycle regulation were significantly affected by EBV status. An almost exclusive upregulation of phosphatidylinositol 3-kinase/AKT/mTOR signaling in EBV+ PBL and a significantly induced expression of NTRK3 in concert with recurrent oncogenic mutations in EBV- PBL hint at a specific therapeutically targetable mechanism in PBL subgroups. Our characterization of a mutational and transcriptomic landscape in PBL, distinct from that of diffuse large B-cell lymphoma and multiple myeloma, substantiates the pathobiological independence of PBL in the spectrum of B-cell malignancies and thereby refines the taxonomy for aggressive lymphomas.

Abstract
Plasmablastic lymphoma (PBL) is a rare but aggressive subtype of diffuse large B-cell lymphoma (DLBCL). The diagnosis of PBL is challenging as its features overlap with lymphoma and myeloma. The most common presentation involves the oral cavity/jaw in human immunodeficiency virus (HIV)-positive patients. It has also been reported in the gastrointestinal (GI) tract, lymph nodes, and soft tissues. Usually, if PBL involves the GI tract, it presents as a gut tumor mass. In this report, we present an HIV-positive patient with PBL presenting with multiple peritoneal nodules. To our knowledge, this is the first case of PBL presenting as multiple peritoneal and retroperitoneal nodules in an HIV-positive patient. This case emphasizes the rare presentation of a rare malignancy, difficulties in establishing a diagnosis, and the importance of proper and timely management.

Abstract
Cutaneous lymphoid neoplasms and cutaneous plasmacytosis are rare in the dog; in human and in veterinary medicine, these have many clinical, cytological, histological, and phenotypic similarities, and a diagnosis of certainty is not easy. The aim of this study is to describe a case of cutaneous non epitheliotropic B-cell lymphoma (CNEBL) with plasmablastic differentiation vs. multiple cutaneous plasmacytosis (CP) in a dog, since the scarce bibliographic data on these topics. A 12-year-old male Beagle dog was presented for multiple, nodular, cutaneous, and subcutaneous, indolent masses disseminated on the whole body. Cytological, histological, flow cytometric, and immunohistochemical examinations, as well as complete radiographic evaluation, echocardiography, and abdominal ultrasound were performed. Cytology, histopathology, flow cytometric, and immunohistochemical examination, performed on the skin lesions, revealed a B-cell phenotype with plasmablastic differentiation. Nevertheless, a final diagnosis could not be achieved and it was categorized as a case of borderline CNEBL with plasmablastic differentiation versus CP. The dog was treated with a COP chemotherapeutic protocol. Total remission was obtained and relapse occurred 120 days later. To our knowledge, specific markers are actually unavailable to certainly differentiate CNEBL and CP in the dog and future studies are needed to improve knowledge on these pathologies in veterinary medicine, since prognosis and therapy are different.

Abstract
Plasmablastic lymphomas and plasmablastic myelomas are malignancies with overlapping clinical and pathological features which pose a diagnostic dilemma and are known to be aggressive with a poor outcome. CD38 is a common immunophenotypic maker for both these malignancies and provides a rationale for using daratumumab-based regimes. We describe a 57-year-old male with a history of end-stage renal disease who underwent a deceased-donor renal transplant maintained on chronic immunosuppression who presented with ascites and was found to have abdominal adenopathy and a lytic lesion in the humerus and diagnosed with a post-transplant lymphoproliferative disorder with features intermediate between plasmablastic lymphoma and plasmablastic myeloma. The patient was subsequently treated with a daratumumab-based regime with an excellent response. This case highlights a rare scenario that poses a diagnostic and therapeutic challenge. As there is no standard of care for the treatment of both these malignancies, this case report also describes the use of daratumumab with a good long-term outcome, especially when the pathological distinction between the two entities is difficult.

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
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
Lymphomas remain a leading cause of morbidity and mortality for HIV-positive patients. The most common lymphomas include diffuse large B-cell lymphoma, Burkitt lymphoma, primary effusion lymphoma, plasmablastic lymphoma and Hodgkin lymphoma. Appropriate approach is determined by lymphoma stage, performans status, comorbidities, histological subtype, status of the HIV disease and immunosuppression. Treatment outcomes have improved due to chemotherapy modalities and effective antiretroviral therapy. This review summarizes epidemiology, pathogenesis, pathology, and current treatment landscape in HIV associated lymphoma.

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
Cancer arises from the accumulation of genetic and epigenetic alterations. Even in the era of precision oncology, carcinogens contributing to neoplastic process are still an important focus of research. Comprehensive genomic analyses have revealed various combinations of base substitutions, referred to as the mutational signatures, in cancer. Each mutational signature is believed to arise from specific DNA damage and repair processes, including carcinogens. However, as a type of carcinogen, tumor viruses increase the cancer risk by alternative mechanisms, including insertional mutagenesis, viral oncogenes, and immunosuppression. In this review, we summarize virus-driven carcinogenesis to provide a framework for the control of malignant cell proliferation. We first provide a brief overview of oncogenic viruses and describe their implication in virus-related tumors. Next, we describe tumor viruses (HPV, Human papilloma virus; HBV, Hepatitis B virus; HCV, Hepatitis C virus; EBV, Epstein-Barr virus; Kaposi sarcoma herpesvirus; MCV, Merkel cell polyoma virus; HTLV-1, Human T-cell lymphotropic virus, type-1) and tumor virus-related cancers. Lastly, we introduce emerging tumor virus candidates, human cytomegalovirus (CMV), human herpesvirus-6 (HHV-6) and adeno-associated virus-2 (AAV-2). We expect this review to be a hub in a complex network of data for virus-associated carcinogenesis.

Abstract
Plasmablastic lymphoma (PBL) is a very rare disease and it is usually considered a human
immunodeficiency virus (HIV)–related B-cell lymphoma that carries a poor prognosis. It
mostly involves the oral cavity, lungs, nasal cavity, gastrointestinal tract, lymph node,
and skin. Therapeutic regimens like dose-adjusted etoposide, vincristine, doxorubicin,
cyclophosphamide, and prednisone (DA-EPOCH) have shown better results in these aggressive
lymphomas. We report a rare case of PBL in an HIV-negative patient who presented to the
clinic with a complaint of left testicular swelling for 3 months. Ultrasound showed an
enlarged left testicle. He underwent a left orchiectomy and the pathology showed PBL with
involvement of the spermatic cord margin. Positron emission tomography scan showed
hypermetabolic mediastinal and hilar lymph nodes. He was started on DA-EPOCH but showed no
response. Accordingly, salvage therapy with bortezomib in addition to ifosfamide
carboplatin and etoposide (B-ICE) chemotherapy was initiated with remarkable response.
Several other regimens can be used in the refractory setting; however, the evidence is
mostly based on retrospective analysis.

Abstract
Primary effusion lymphoma (PEL) is defined as a HHV-8-associated large B-cell lymphoma, which favors HIV-infected young adults, typically presenting as a serous (pleural, pericardial, or peritoneal) effusion with no identifiable tumor mass. Uncommon instances of lymphoid proliferations with the same morphology, immunophenotype, and molecular features as PEL, but occurring as a solid tumor mass without serous cavities involvement, have been termed extracavitary (or solid) variant of PEL. We hereby report the exceptional case of a HIV-associated extracavitary PEL primarily localized to the skin and exhibiting a panniculitis-like presentation. Primary cutaneous presentation of extracavitary PEL is exceedingly uncommon, with only 6 cases previously described in the literature. In light of its atypical immunophenotype, the differential diagnosis in case of skin involvement by extracavitary PEL is challenging: demonstration of HHV-8 infection in neoplastic cells is of pivotal importance. Our case is further atypical in that the lymphoid proliferation underwent complete and protracted regression solely by establishment of highly active antiretroviral therapy.

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
PURPOSE Plasmablastic lymphoma (PBL) is a rare and aggressive B-cell malignancy with a heterogenous clinical and prognostic spectrum, determined by multiple factors, including age, HIV- and MYC-status. While there exist several validated scoring systems for diffuse large B-cell lymphoma, which incorporate basic clinical features (age, lactate dehydrogenase, sites of (extranodal) involvement, stage and performance), none of these have been systematically assessed in PBL. METHODS We determined the (age-adjusted; aa)-International Prognostic Index (IPI), revised IPI (R-IPI), and National Comprehensive Cancer Network IPI (NCCN-IPI) in a comprehensive multi-center cohort (n = 78) of PBL patients. Further, all indices were comparatively investigated for model quality and concordance. RESULTS Univariate analysis revealed significant prognostic capabilities for all indices, all of which identified a subgroup with favorable outcome. Discriminatory power between patients with less benign prognosis and especially refractory disease exhibited significant variability. Subsequently, stratified models for each risk score were compared employing corrected Akaike's information criterion (cAIC) and Harrel's concordance index (c-index). Here, the NCCN-IPI outperformed both IPI and R-IPI regarding c-index with ambiguous cAIC results, underlining its clinical utility and suggesting it for preferential use in clinical practice. CONCLUSION Our current observations support the use of the IPI and its enhanced derivatives in PBL patients. There is, however, a distinct requirement for novel prognostic tools to better delineate subgroups at risk for early relapse or refractory disease as well as late relapse. A comprehensive molecular characterization of a clinically annotated cohort of PBL patients is therefore urgently warranted.

Abstract
Plasmablastic lymphoma (PBL) is an aggressive lymphoma commonly associated with HIV infection. It most commonly presents in the oral cavity and rarely involves the kidney. Herein, we report a case of HIV positive male with renal involvement of PBL. The patient presented with unilateral severe hydronephrosis with unaltered renal functions. Despite aggressive management, there was an early relapse and the patient died within 2 years of the diagnosis. Despite the recent advances in the therapy of HIV-associated aggressive lymphomas, patients with PBL have a poor prognosis. Multimodal treatment with chemotherapy, newer targeted and biological agents, along with hematopoietic stem cell transplantation is essential for the treatment of PBL.

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
Background
Plasmablastic lymphoma (PBL) is a rare aggressive B cell lymphoma that is commonly encountered in patients with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS). In this case series, we describe the clinicopathological features of cases of PBL seen at a tertiary care center in South India.
Materials and Methods
Medical records of patients diagnosed with PBL between January 2009 and November 2017 were reviewed. PBL was defined as per the World Health Organization 2016 classification for hematopoietic and lymphoid neoplasms. The slides were reviewed with hematoxylin and eosin along with immunohistochemistry (IHC) including CD45, CD20, PAX5, CD79a, CD3, CD5, CD138, MUMI, EMA, ALK, and Ki67. Epstein-Barr virus (EBV) association was documented by rapid in situ hybridization (RISH) studies wherever possible. The demographic data, clinical presentation, treatment details, and outcomes are elaborated using descriptive statistics.
Results
During the study period, nine patients with PBL were identified. The median age at presentation was 47 years (range: 36–54 years). All patients had associated HIV/AIDS, eight (89%) had extranodal disease, and six (66%) had advanced clinical stage (stage III). All biopsies were positive for CD45, CD138, and MUM1, and negative for CD79a and T cell markers with a high Ki67 proliferation index (85–90%); CD20 was faint positive in one patient, and CD56 was positive in one (11%) patient. EBV-RISH was tested in two patients and was positive in one. Bone marrow was uninvolved in all the cases. At the time of last follow-up, three patients were alive. Treatment details were available in six patients. With frontline therapy, four patients achieved a complete remission (CR) and one patient developed progressive disease. Three of four patients in CR are alive till the last follow-up.
Conclusion
PBL is a rare form of lymphoma with predominant association with HIV, extranodal location, and characteristic IHC pattern.

Abstract
Introduction: Plasmablastic lymphoma (PBL) is a rare lymphoma associated with immunosuppression. It is strongly associated with immunosuppression (human immunodeficiency virus [HIV]) and often occurs within the oral cavity. PBL is also seen in patients receiving immunosuppressive therapy; however, despite its predisposition for the immunocompromised patients, PBL has been diagnosed in immunocompetent patients. Aim: This study aims to prognostic factors and outcome of PBL in immunocompromised and in immunocompetent patients. Materials and Methods: We conducted a retrospective study at our institute from the year 2008 to 2015. Results: A total of 13 patients (8 males and 5 females) with PBL were identified. Eight patients (61.5%) had extraoral PBL (median age 30.2 years) and 5 patients (38.5%) had oral PBL (median age 44 years). Most common extraoral site was gastrointestinal tract. Eight (61.5%) out of 13 patients were HIV positive. More than 50% of patients had Ann Arbor Stage III or IV. All the cases were CD20 negative and CD138 positive. Seven out of 13 patients had Ki-67 more than 80%. Nine patients received cyclophosphamide, doxorubicin, vincristine, and prednisone chemotherapy. Three patients were on best supportive care due to poor performance status (PS). One patient received intensive chemotherapy with CODOX-M/IVAC. The median overall survival was 9 months in HIV-positive patients and 6 months in HIV-negative patients. The prognosis was worse in patients with Ki-67 of >80%. Statistical Analysis: Survival curves were generated using the Kaplan–Meier method and analyzed using log-rank test and Fisher's t-test. Conclusion: The present study confirms that PBL in both HIV-positive and in HIV-negative patients has an overall unfavorable outcome. The most important prognostic factors are stage, ki-67, and the Eastern Cooperative Oncology Group PS of the patient at the time of presentation.
