BACKGROUND: Plasmablastic lymphoma (PBL), initially described in 1997 in the oral cavity of HIV positive patients, is now recognized as a distinct aggressive and rare entity of diffuse large B-cells lymphoma (DLBCL) by the WHO (World Health Organization) classification. Since the original description, others cases have been reported. However, these are largely derived from case reports or small series limiting any definitive conclusions on clinical characteristics and outcome. PATIENTS AND METHODS: The clinical, biological, pathological features and outcome of a cohort including 135 patients with PBL, from LYSA centers in France and Belgium, were reported and analyzed...

Plasmablastic lymphoma (PBL) is a rare distinct subtype of aggressive diffuse large B-cell lymphoma and a notoriously hard to treat entity with a dismal prognosis in both HIV-negative and HIV-positive patients. Clinicians often face the question of second or third line treatment. As the treatment options with novel agents in lymphomas are rapidly evolving, more and more options beyond standard chemotherapy are available. In connection with a review of treatment options with novel lymphoma agents, we present a case report of a patient with a complete remission after the administration of brentuximab vedotin and lenalidomide...

Plasmablastic B-cell malignancies include plasmablastic lymphoma and subsets of multiple myeloma and diffuse large B-cell lymphoma (DLBCL). These diseases can be difficult to diagnose and treat, and lack well-characterised cell line models. Here, immunophenotyping and FOXP1 expression profiling identified plasmablastic characteristics in DLBCL cell lines HLY-1 and SU-DHL-9, associated with CTNNAL1, HPGD, RORα, IGF1 and/or vitamin D receptor (VDR) transcription. We demonstrated VDR protein expression in primary plasmablastic tumour cells, and confirmed in cell lines expression of both VDR and the metabolic enzyme CYP27B1, which catalyses active vitamin D3 production...

Plasmablastic lymphoma (PBL) represents a rare type of non-Hodgkin lymphoma associated with human immunodeficiency virus (HIV) infection. The impact of highly active antiretroviral therapy (HAART) in this tumor is poorly known due to its small incidence. This study reports a case of a 33-year-old HIV-positive woman who was referred to the Stomatology Department complaining about a painful gingival growth and cervical nodule both with 20 days of evolution. The lesions appeared 7 months after the patient stopped HAART...

Plasmablastic lymphoma (PBL) is a rare subtype of diffuse large B cell lymphoma (DLBCL), often associated with HIV infection. We present a case of a 53-year-old HIV-negative man with untreated hepatitis C viral infection who presented with abdominal pain and lymphadenopathy. Lymph node and bone marrow biopsies were consistent with plasmablastic lymphoma. He had partial response (PR) to 6 cycles of EPOCH but disease progressed seven weeks later. Repeat biopsy was consistent with plasmablastic lymphoma. Three cycles of bortezomib, ifosfamide, carboplatin, and etoposide (B-ICE) chemotherapy resulted in a partial response (PR)...

BACKGROUND: Follicular lymphoma (FL) is an indolent non-Hodgkin lymphoma that has a risk of transformation to more aggressive lymphoma. Relatively little is known about the non-malignant B-cell and T-cell subset composition within the tumor microenvironment and whether altered phenotypes are associated with patterns of lymphoma B-cell heterogeneity. METHODS: Two mass cytometry (CyTOF) panels were designed to immunophenotype B and T cells in FL tumors. Populations of malignant B cells, non-malignant B cells, and T cells from each FL tumor were identified and their phenotypes compared to B and T cells from healthy human tonsillar tissue...

First identified as a distinct disease entity in HIV-positive patients, plasmablastic lymphoma is a rare aggressive disease which arises predominantly in men and is associated with immunodeficiency of all causes. Although its exact etiology is poorly understood, Epstein-Barr virus infection and MYC gene aberrations have been implicated in its development in both HIV-positive and HIV-negative patients. The disease typically involves extranodal sites with a predilection for the oral cavity but may occur in other locations...

Effusion-based lymphoma is a rare and unique type of large B-cell lymphoma presenting in effusion without a mass lesion. It shares many clinicopathological features with primary effusion lymphoma (PEL), but is distinct from PEL by the absence of HHV8 association. Double hit lymphoma (DHL) is an aggressive B-cell lymphoma, defined by concurrent rearrangement of MYC and BCL2 or BCL6. DHL often presents as lymphadenopathy or an extranodal mass, but rarely occurs in effusion. Here we report a 61-year-old male with alcoholic cirrhosis presenting as massive ascites and left pleural effusion...

Richter syndrome (RS) is considered as the rare development of an aggressive lymphoid malignancy in a preexisting small lymphocytic lymphoma/chronic lymphocytic leukemia. The most common aggressive lymphoma developing in this setting is diffuse large B-cell lymphoma, but classical Hodgkin lymphoma and other much rarer entities such as prolymphocytic lymphoma and dendritic cell sarcoma are also described, most frequently in the progression of the disease over time. A clonal relation between the 2 neoplastic proliferations can be frequently found, whereas clonally unrelated cases are commonly considered as independent tumors, probably due to a variable combination of multiple causes, responsible independently for the 2 neoplasms...

Non-Hodgkin's lymphoma (NHL) is the third common malignant lesion of the oral region. Plasmablastic lymphomas are rare, aggressive neoplasms occurring mostly in human immunodeficiency virus (HIV) infected individual which accounts for approximately 2.6% of all NHL. It usually presents as a diffuse growth and with diffuse pattern of histological presentation. It is very difficult to differentiate this lymphoma from other NHL. Immunohistochemical evaluation of various markers is an important criteria of the diagnostic protocol...

BACKGROUND: Primary intracranial plasmablastic lymphoma (PIPBL) is a rare malignant tumor. CASE DESCRIPTION: We present a case of PIPBL in a 32-year-old man who complained of a progressive growing, painful mass on the right parieto-occipital part of head. Computed tomography and magnetic resonance imaging revealed a homogeneously enhanced mass with partial bone destruction. The patient underwent total resection and cranioplasty in one stage. Histopathologic examination showed large tumor cells with immunoblast-like nuclei...

Plasma-cell post-transplantation lymphoproliferative disorder (PC-PTLD) is a rare monomorphic PTLD entity divided into plasma cell myeloma (PCM) and plasmacytoma-like lesion (PLL) PTLD. To date, there are no exhaustive published cytogenetic data on PC-PTLD. We report array-based comparative genomic hybridization (aCGH) of 10 cases of PCM and PLL-PTLD. Patients had received kidney (n = 6), heart (n = 2), lung (n = 1) or bone marrow (n = 1) transplantation. There were six men and median age at time of PTLD was 56...

Post-transplant lymphoproliferative disorders (PTLD) are a serious complication of transplantation with a high mortality. Most PTLD present within the first year of transplantation and are associated with Epstein-Barr virus (EBV) infection. Plasmablastic lymphoma (PBL) is a rare but aggressive disease originally described in patients with HIV, presenting most commonly in the jaw and oral mucosa. To our knowledge, this is the first case of PBL presenting as PTLD of the lung in a HIV and EBV negative patient...

Anaplastic lymphoma kinase-positive large B-cell lymphoma (ALK LBCL) is a rare, aggressive subtype of diffuse large B-cell lymphoma with characteristic ALK rearrangements. Diagnosis of ALK LBCL can be challenging because of its rarity, unique morphologic characteristics, and unusual immunophenotypic features, which significantly overlap with other hematologic and nonhematologic neoplasms. The purpose of this study is to further explore the clinicopathologic features of ALK LBCL to ensure the awareness and accurate diagnosis of this entity...

Plasmablastic lymphoma is a rare entity accounting for around 2.7% of all AIDS-related lymphomas. The oral cavity and gastrointestinal tract are the most common sites involved. We report a case of a 34-year-old HIV-positive woman with a rare presentation of cutaneous nodules all over the body. Due to overwhelming tumour burden, she developed tumour lysis syndrome during her hospital stay and succumbed to the illness.

Classically, the HIV/AIDS-related lymphomas are of the B cell type and involve the central nervous system and the abdominal cavity. Primary maxillary sinus lymphoma is rare. Plasmablastic lymphoma (PBL) is an aggressive form of non-Hodgkinvs lymphoma, and is extremely rare. Here we present a case of plasmablastic lymphoma with primary site being maxillary sinus, a rare location.

Plasmablastic lymphoma is an uncommon aggressive non-Hodgkin B-cell lymphoma type defined as a high-grade large B-cell neoplasm with plasma cell phenotype. Genetic alterations in MYC have been found in a proportion (~60%) of plasmablastic lymphoma cases and lead to MYC-protein overexpression. Here, we performed a genetic and expression profile of 36 plasmablastic lymphoma cases and demonstrate that MYC overexpression is not restricted to MYC-translocated (46%) or MYC-amplified cases (11%). Furthermore, we demonstrate that recurrent somatic mutations in PRDM1 are found in 50% of plasmablastic lymphoma cases (8 of 16 cases evaluated)...
