Abstract
Plasmablastic lymphoma (PBL) occurs in the setting of immunodeficiency, in association with human immunodeficiency virus (HIV) infection, in elderly patients, and in the posttransplantation state. It is exceptionally rare in children. PBL is an aggressive lymphoma with a poor prognosis. We present a case of pediatric PBL in an HIV-positive child with suspicion of a concomitant underlying immune deficiency state other than HIV. A 7-year-old girl presented to the pediatric emergency department with complaints of fever and painful swelling on the left side of her face for 15 days, associated with headache, snoring, and difficulty in breathing. She had a history of watery diarrhea, oral thrush, recurrent fever, and hospitalizations for skin infections since the age of 1 year. Histopathological findings were consistent with PBL. Her HIV RNA polymerase chain reaction was positive. She was offered chemotherapy based on the FAB/LMB 96 protocol. This case demonstrates an aggressive presentation of a rare entity, HIV-associated PBL, in a child, with underlying immunodeficiency and highlights the issues which caused a significant challenge in making the diagnosis. The presence of HIV infection and contradicting other immunologic investigations posed a dilemma in establishing an association of PBL in this child. The outcome of patients with this tumor is associated with high mortality.

Stage, age, and EBV status impact outcomes of plasmablastic lymphoma patients: a clinicopathologic analysis of 61 patients. J Hematol Oncol 2015; 8:65.

Abstract
Background Plasmablastic lymphoma (PBL) is a rare aggressive neoplasm with lymphoid and plasmacytic differentiation that is commonly associated with immunodeficiency and an unfavorable prognosis. Clinicopathologic features have been largely derived from cases reports and small series with limited outcome analyses. Patients and methods The demographic, clinicopathologic features, and clinical outcomes of a cohort of 61 patients with PBL were reviewed and analyzed. Results Patients had a median age of 49 years (range 21–83 years) and most (49/61; 80 %) were men. Human immunodeficiency virus (HIV) status was available for 50 patients: 20 were HIV-positive and 30 HIV-negative. Twenty-three patients were immunocompetent. Abdominal/gastrointestinal complaints were the most common presenting symptoms, reported in 14 of 47 (30 %) of patients. At presentation, 24 of 43 (56 %) patients had stage III or IV disease. Epstein-Barr virus (EBV) was detected in 40 of 57 (70 %) cases. MYC rearrangement was identified in 10/15 (67 %) cases assessed, and MYC overexpression was seen in all cases assessed regardless of MYC rearrangement status. HIV-positive patients were significantly younger than those who were HIV-negative (median 42 vs. 58 years; p = 0.006). HIV-positive patients were also significantly more likely to have EBV-positive disease compared with HIV-negative patients (19/19, 100 % vs. 15/29, 52 %; p = 0.002). Patients who received CHOP chemotherapy tended to have better overall survival (OS) compared with those who received hyperfractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone (hyper-CVAD) (p = 0.078). HIV status had no impact on OS. Patients with EBV-positive PBL had a better event-free survival (EFS) (p = 0.047) but not OS (p = 0.306). Notably, OS was adversely impacted by age ≥50 years (p = 0.013), stage III or IV disease (p = <0.001), and lymph node involvement (p = 0.008). Conclusions The most significant prognostic parameters in patients with PBL are age, stage, and, to a lesser extent, EBV status. In this study, two-thirds of PBL cases assessed were associated with MYC rearrangement and all showed MYC overexpression.

Abstract
AIMS Extramedullary plasmacytomas are often localized, clinically indolent neoplasms, and affected patients usually respond to radiation therapy or limited cycles of chemotherapy. In contrast, plasmablastic lymphomas are clinically aggressive neoplasms composed of immunoblastic or plasmablastic cells and associated with more mature plasma cells in some cases. Patients with plasmablastic lymphoma usually have a poor prognosis despite aggressive chemotherapy. Evidence of Epstein-Barr virus (EBV) infection is uncommon in plasmacytoma, but common in plasmablastic lymphoma, and is therefore helpful in differential diagnosis. The aim of this study is to describe four cases of plasmacytoma arising in immunocompetent individuals that were diffusely positive for Epstein-Barr virus-encoded small RNA as shown by in-situ hybridization. METHODS AND RESULTS We describe the clinicopathological and immunophenotypic findings of four EBV-positive plasmacytomas arising in immunocompetent patients. These tumours were characterized by diffuse proliferation of mature-appearing plasma cells intermixed with a briskly reactive, CD8-positive, TIA-1-positive cytotoxic T-cell infiltrate. Long-term follow-up was available for all patients, and all were alive and free of disease at last follow-up (median 43.4 months). CONCLUSIONS We suggest the term EBV-positive plasmacytoma in immunocompetent patients for these lesions. It is essential to distinguish these tumours from plasmablastic lymphoma, as the latter diagnosis is associated with a much poorer prognosis, and patients require much more aggressive therapy.

Abstract
Plasmablastic lymphoma (PBL) is an aggressive high grade non-Hodgkin lymphoma which occurs predominantly in adult patients who are concomitantly afflicted with HIV infection. In contrast to several reports and studies of PBL in adult patients, PBL has very rarely been reported in pediatric patients. This article hereby provides collaborative clinicopathologic information of de novo PBL diagnosed in 3 pediatric patients with concomitant HIV infection. Cognizance of this rare tumor in the pediatric population coupled with antiretroviral therapy and prompt initiation of multimodality treatment may, in the future, facilitate improved outcome in pediatric patients with PBL.

Abstract
We have compared histologic features and gene expression profiles of newly identified plasmacytomas from NFS.V(+) congenic mice with plasmacytomas of IL6 transgenic, Fasl mutant, and SJL-beta2M(-/-) mice. NFS.V(+) tumors comprised an overlapping morphologic spectrum of high-grade/anaplastic, intermediate-grade/plasmablastic, and low-grade/plasmacytic cases with similarities to subsets of human multiple myeloma and plasmacytoma. Microarray and immunohistochemical analyses of genes expressed by the most prevalent tumors, plasmablastic plasmacytomas, showed them to be most closely related to immunoblastic lymphomas, less so to plasmacytomas of Fasl mutant and SJL mice, and least to plasmacytic plasmacytomas of IL6 transgenic mice. Plasmablastic tumors seemed to develop in an inflammatory environment associated with gene signatures of T cells, natural killer cells, and macrophages not seen with plasmacytic plasmacytomas. Plasmablastic plasmacytomas from NFS.V(+) and SJL-beta2M(-/-) mice did not have structural alterations in Myc or T(12;15) translocations and did not express Myc at high levels, regular features of transgenic and pristane-induced plasmacytomas. These findings imply that, as for human multiple myeloma, Myc-independent routes of transformation contribute to the pathogenesis of these tumors. These findings suggest that plasma cell neoplasms of mice and humans exhibit similar degrees of complexity. Mouse plasmacytomas, previously considered to be homogeneous, may thus be as diverse as their human counterparts with respect to oncogenic mechanisms of plasma cell transformation. Selecting specific types of mouse plasmacytomas that relate most closely to subtypes of human multiple myeloma may provide new opportunities for preclinical testing of drugs for treatment of the human disease.

Abstract
Ten cases of multiple myeloma are reported in which there were a large number of plasma cells with excessively convoluted or lobulated nuclei. These cases represent 3% of the 297 evaluable multiple myeloma patients treated at our institution over a 22-year period. All 10 had intermediate or advanced stage disease at the time of diagnosis, and all have died after a mean survival of 19.5 months. Ultrastructural features of 2 cases are described. When found in abundance, such cells can cause difficulty in establishing a morphologic diagnosis of multiple myeloma because of their resemblance to other cell types. Therefore, it may be necessary to perform immunoperoxidase staining and/or electron microscopy to confirm the plasmacytic identity of these cells. The findings add further support to the contention that the presence of excessive nuclear convolutions is not a completely reliable indication of T-cell, as opposed to B-cell, lineage.

Abstract
A patient is reported who had disseminated immunoblastic proliferation that emerged during the course of alpha chain disease. This proliferation was characterized by overt marrow invasion together with osseous and neurologic manifestations. On immunoelectron microscopic study, the malignant immunoblasts displayed varying degrees of cytoplasmic maturation and constituted a morphologic spectrum of alpha-chain-synthesizing cells, ranging from immature blasts without endoplasmic reticulum development to relatively mature plasmablasts; alpha chain was not expressed at the surface of these cells. The general features of the overt malignant stage of alpha chain disease are reviewed in reference to this unusual case. The implications of the cellular findings are discussed with regard to the maturation stage of malignant immunoblasts.

Abstract
To test whether highly anaplastic myeloma and immunoblastic lymphoma are truly identical disease processes, simultaneous series were compared in respect to cytomorphologic features, immunoglobulin content or secretion, clinical and laboratory findings, and patient survival. Although the series partially overlapped in each studied feature, different trends served to distinguish them. Of the 14 patients with myeloma, all were dead at two years, whereas six of the 22 patients with lymphoma were disease-free at 35 to 78 months. Only 50 percent of patients with myeloma received intensive chemotherapy, whereas all 19 patients with stage III or IV lymphoma received such therapy. Myelomas secreted predominantly IgA heavy chain rather than IgG and lambda light chain rather than kappa. Lymphomas contained predominantly IgM rather than IgG and kappa rather than lambda. There were no IgM myelomas and no IgA lymphomas. The shorter survival of patients with the extremely anaplastic form of myeloma, as compared with patients who had immunoblastic lymphoma, may relate, in part, to prior therapy for previous lower grade myeloma; however, intrinsic differences in the nature of these two disease processes are reflected in their disparate immunologic characteristics.
