Abstract:. Plasmablastic lymphoma (PBL) is a distinctive B-cell neoplasm which shows diffuse proliferation of large neoplastic cells, most of which resemble B-immunoblasts and have immunophenotype of plasma cells. PBL was originally described as a rare variant of diffuse large B-cell lymphoma (DLBCL) involving the oral cavity and occurring in the clinical setting of HIV[1] and latent Epstein-Barr virus (EBV) infection. We report a case of 49 year old HIV positive male with PBL involving the colon and rectum, who initially presented with constipation and rectal bleeding. A CT scan was performed which showed peri-colonic infiltration, rectal wall thickening and involvement of iliac, inguinal and mesenteric lymph nodes. A subsequent colonoscopy showed multiple lesions in the colon and rectum. Biopsy of these lesions showed monotonous proliferation of large lymphoid cells with immunoblastic features and immunohistolochemical report was consistent with the PBL.. ...

1142 Anaplastic large cell lymphoma (ALCL) represents a distinct clinicopathologic entity characterized genetically by rearrangements of the ALK gene at chromosome region 2p23, which is most often seen as a t(2;5)(p23;q35). Abnormalities of 2p23 may be cytogenetically visible and/or can be detected by using an ALK-specific fluorescence in situ hybridization (FISH) probe. The presence of an ALK rearrangement is associated with a better prognosis compared to ALK rearrangement-negative ALCL. When the primary genetic alteration that defines a disease is associated with a good prognosis, it is crucial to look for specific secondary genetic changes that might lead to disease progression or alter the aggressiveness of the disease. ALCLs exhibit a bimodal age distribution and have an overall younger mean age at presentation. To the best of our knowledge, secondary cytogenetic changes in ALCL have not been investigated to date. We have analyzed 36 ALCL cases containing cytogenetic abnormalities; 19 of ...

Therefore all of these techniques could also be used to identify tumours particularly suitable for treatment with CDK inhibitors. Patients with mantle cell lymphoma (MCL) could be selected for treatment with a CDK inhibitor using diagnostic tests outlined herein. MCL is a distinct clinicopathologic entity of non-Hodgkins lymphoma, characterized by proliferation of small to medium-sized lymphocytes with co-expression of CDS and CD20, an aggressive and incurable clinical course, and frequent t(l I;14)(ql3;q32) translocation. Over-expression of cyclin Dl mRNA, found in mantle cell lymphoma (MCL), is a critical diagnostic marker. Yatabe et al (Blood. 2000 Apr 1;95(7):2253-61) proposed that cyclin Dl-positivity should be included as one of the standard criteria for MCL, and that innovative therapies for this incurable disease should be explored on the basis of the new criteria. Jones et al (J Mol Diagn. 2004 May;6(2):84-9) developed a real-time, quantitative, reverse transcription PCR assay for ...

Acute myeloid leukemia (AML) with inv(3)(q21q26.2)/t(3;3)(q21;q26.2) is a distinct clinicopathologic entity with a poor prognosis. However, double inv(3)(q21q26.2) is extremely rare in AML. We report here 3 cases analyzed by oligonucleotide microarray comparative genomic hybridization (aCGH) and single nucleotide polymorphism (SNP). Clinicopathologic, cytogenetic and molecular findings were correlated with clinical outcome to better understand the entity. The study group included one man and two women at 56-74 years of age. The AML arose from myelodysplastic syndrome in one patient and from chronic myelomonocytic leukemia in another patient. Monosomy 7 was found as additional cytogenetic finding in one patient. One patient had a single inv(3) in the initial clone and acquired double inv(3) as part of clonal evolution. EVI1 (MECOM) rearrangement was confirmed using metaphase/interphase fluorescence in situ hybridization (FISH). Microarray (aCGH + SNP) data analysis revealed that the double inv(3) was a

Background: Inflammatory breast cancer (IBC) is a distinct clinicopathologic entity that carries a worse prognosis relative to non-IBC breast cancer even when matched for biomarkers (ER/PR/HER2). Genomic profiling of IBC cases may identify alterations that suggest response to targeted therapies, but is best implemented by an integrated NGS assay capable of detecting all classes of genomic alterations (GA).. Methods: Hybridization capture of 3769 exons of 236 cancer-related genes and 47 introns from 19 genes that are frequently rearranged in cancer were fully sequenced to high, uniform coverage from a commercial CLIA-certified laboratory (Foundation Medicine).. Results: Of 2,208 clinical breast cancer cases assayed, 55 IBC cases were identified, and of the 50 cases for which hormone receptor and HER2/neu status were know, 34% were ER-/PR-/HER2- (TNBC). IBC cases harbored 274 GA with an average of 5.0 GA/tumor (range 1-15). At least one alteration associated with an FDA approved therapy or ...

Oropharyngeal lymphomas are rare, typically high-grade neoplasms. We describe a case of plasmablastic lymphoma that originated in the oropharynx of a 40-year-old man who was positive for human immunodeficiency virus (HIV). The diagnosis was based on fine-needle aspiration cytology of the mass followed by histopathologic examination supplemented with immunophenotyping. The mass was excised, but the patient refused antiretroviral therapy, and he died within 6 months of the diagnosis. In HIV-positive patients, non-Hodgkin lymphomas frequently involve sites, including the oropharynx, that are unusual in patients without HIV.. ...

Epstein-Barr virus (EBV) is a gamma-herpes virus that widely infects human populations predominantly at an early age but remains mostly asymptomatic. EBV has been linked to a wide spectrum of human malignancies, including nasopharyngeal carcinoma and other hematologic cancers, like Hodgkins lymphoma, Burkitts lymphoma (BL), B-cell immunoblastic lymphoma in HIV patients, and posttransplant-associated lymphoproliferative diseases. EBV has the unique ability to establish life-long latent infection in primary human B lymphocytes. During latent infection, EBV expresses a small subset of genes, including 6 nuclear antigens (EBNA-1, -2, -3A, -3B, -3C, and -LP), 3 latent membrane proteins (LMP-1, -2A, and -2B), 2 small noncoding RNAs (EBER-1 and 2). On the basis of these latent gene expression, three different latency patterns associated with the types of cancers are recognized ...

Established from the pleural effusion of a 60-year-old man with refractory immunoblastic B cell lymphoma progressed from follicular centroblastic/centrocytic lymphoma in 1990; cells were described to carry the t(14;18) leading to IGH@-BCL2 (IGH-BCL2) fusion gene and to express BCL2 mRNA; the original culture was a mixture of EBV - and EBV + cells, of which the EBV - cells were isolated and clonally ...

INTRODUCTION: Orbital cellulitis is an uncommon, potentially devastating condition that, when not promptly and adequately treated, can lead to serious sequelae. The presenting clinical signs are proptosis, swelling, ophthalmoplegia, pain and redness of the peri-orbital tissues. A number of cases have been reported in which these symptoms have been mistakenly interpreted as being secondary to an orbital infection whilst, in fact, other pathology was present. DISCUSSION: We add another case in which, on clinical grounds and after radiological assessment and laboratory tests, a working diagnosis of orbital cellulitis of the left eye was made. It was only after histopathological analysis of a soft tissue specimen from the maxillary sinus that a diagnosis of an AIDS-related plasmablastic lymphoma was made. The patient was referred to the department of haematology where chemotherapeutic treatment for the lymphoma and the HIV infection was started. This case report adds another differential diagnosis ...

AIDS-related lymphoma describes lymphomas occurring in patients with acquired immunodeficiency syndrome (AIDS). A lymphoma is a type of cancer arising from lymphoid cells. In AIDS, the incidences of non-Hodgkins lymphoma, primary cerebral lymphoma and Hodgkins disease are all increased. There are three different varieties of AIDS-related lymphoma: Diffuse large B-cell lymphoma, B-cell immunoblastic lymphoma, and Burkitts lymphoma (small non-cleaved cell lymphoma). The symptoms of AIDS-related lymphoma can include: weight loss, fever, and night sweats. Non-Hodgkins lymphoma (NHL) is present in about 1%-3% of HIV seropositive people at the time of the initial diagnosis of HIV. However, it is believed that such patients have been seropositive for a prolonged period, but have simply not had their infections recognized previously. This is so because immunodysregulation must exist for an extended interval of time, in order for a lymphoproliferative process to evolve in that context. Primary ...

AU - McKenna, R. W.. PY - 1986/1/1. Y1 - 1986/1/1. N2 - Morphologic and clinical features of 30 patients with peripheral T-cell lymphoma (PTCL) were studied with particular attention to bone marrow and blood manifestations. Twenty-four (80%) patients had marrow involvement with lymphoma in trephine biopsies at initial diagnosis; two other patients subsequently developed marrow involvement. The bone marrow lesions were diffuse in 58% of the cases and focal, nonparatrabecular in 42%. A morphologic spectrum of lymphoma cells was seen with cases classified into small cell, mixed cell, and large cell/immunoblastic lymphoma. The bone marrow lesions were characterized by a heteromorphous population of lymphocytes, prominent vascularity with endothelial cell proliferation, reticulin fibrosis, and a polycellular ...

Dolphins and humans are exposed to the same toxins in seafood. Over 2 billion people worldwide rely on seafood as their major source of protein and 60% of people live in coastal areas. Resident coastal dolphins are exposed to marine pollution in the same fashion as humans who frequently consume seafood, thus any indication of disease in dolphins has implications both for humans who eat regularly from the same areas and/or are otherwise exposed to the same toxins.Although dolphins share most human mammalian genes, including CYP1A and CYP2B, they lack the ability to adequately catabolize type I and II dioxins, which therefore preferentially accumulate. Unfortunately, observed results of these bioaccumulations are suppressed immunity, infections and cancers particularly B-cell lymphomas and myeloma-like immunoblastic lymphomas (Bossart: J. Vet Diagn Invest 9: 454-458, 1997 ...

Discussion: Myoepithelial carcinomas (or malignant myoepitheliomas) are rare malignant salivary gland neoplasms in which the tumor cells show myoepithelial differentiation. The entity was first described by Stromeyer et al. in 1975. The tumor was included in the WHO classification of salivary gland neoplasms as a distinct clinicopathologic entity in 1991. About 60% to 70% of myoepithelial carcinomas develop in a benign mixed tumor (carcinoma ex pleomorphic adenoma), and the remainder arise de novo. Histologically, malignant myoepitheliomas are composed of one or several cell types: spindle, plasmacytoid, epithelioid, and clear cells. Frequently, one of the cell types predominates. The neoplastic cells grow either as multiple nodules or as large solid sheets separated by variable amounts of intervening hyaline or myxoid stroma. By far, the multinodular growth pattern is more prevalent. The cytologic features generally reflect the histology. The cytologic smear can show spindle, epithelioid or ...

Kappa and Lambda light chain stainings confirmed absence of clonicity.. The final diagnosis is Castleman lymhadenopathy, hyaline-vascular variant.. Castlemans disease (CD), also called angiofollicular lymph node hyperplasia, comprises at least two distinct forms, unicentric (UCD) and multicentric (MCD). Its pathologic classification includes hyaline-vascular variant, plasma cell variant, mixed variant, and less frequent plasmablastic variant. Localized form was first described in 1956 by Benjamin Castleman. This form includes dominantly hyaline-vascular variant and a small amount of plasma cell variant and mixed variant. Multicentric Castlemans disease (MCD) is frequently associated with HHV-8 infection in immunodeficient or HIV-infected patients. MCD is more likely to be plasma cell variant or plasmablastic variant. Hematologic malignancy such as plasmablastic lymphoma arising from HHV-8 associated MCD has been reported. Kaposis sarcoma, another HHV-8-related disease, is also highly ...

Primary effusion lymphoma (PEL) is a rare subtype of large B-cell lymphoma representing approximately 4% of all immunodeficiency syndrome (AIDS)-related lymphomas. It occurs in two forms; classic and extracavitary/solid. PEL classically presents as a lymphomatous effusion in the pleural, pericardial, or peritoneal cavities, but may also manifest as extracavitary masses involving the gastrointestinal tract, lungs, skin and central nervous system. PEL is universally associated with the human herpesvirus 8 (HHV8) and most often occurs in the setting of immunodeficiency. Additionally tumor cells often show coinfection with Epstein-Barr Virus (EBV).. The tumor cells show morphologic variability which ranges from immunoblastic/plasmablastic to anaplastic. The nuclei are large and round to more irregular or lobated with prominent nucleoli. On histological sections these cells may appear more uniform and monotonous than on cytologic specimens. Immunophenotypically the lymphoma cells usually express ...

Plasmablastic lymphoma (PBL) is a rare and aggressive form of B-cell non-Hodgkin lymphoma. This subtype of lymphoma has a post-germinal center cell-of-origin called the plasmablast, and the immunophenotype is more consistent with that of a plasma cell than a lymphocyte. Because of these unique features, PBL is notoriously difficult to treat. Case reports and small reviews have evaluated the addition of agents directed against plasma cell disorders in combination with traditional lymphoma-directed regimens. We describe the largest case series to date, with the longest follow-up, evaluating bortezomib in combination with etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin (V-EPOCH) for the treatment of PBL ...

Recently, diffuse-large-B-cell lymphoma (DLBCL) associated with serum IgM monoclonal component (MC) has been shown to be a very poor prognostic subset although, detailed pathological and molecular data are still lacking. In the present study, the clinicopathological features and survival of IgM-secreting DLBCL were analyzed and compared to non-secreting cases in a series of 151 conventional DLBCL treated with R-CHOP. IgM MC was detected in 19 (12.5%) out of 151 patients at disease onset. In 17 of these cases secretion was likely due to the neoplastic clone, as suggested by the expression of heavy chain IgM protein in the cytoplasm of tumor cells. In IgM-secreting cases immunoblastic features (p

First-line therapy in Primary Mediastinal Large B-Cell Lymphoma: first generation compared to third generation chemotherapy, and the increase in efficacy due to rituximab

The US Food and Drug Administration has​ approved the medicine Keytruda for the treatment of Primary mediastinal large B-cell lymphoma (PMBCL).

Anisakidosis, human infection with nematodes of the family Anisakidae, is caused most commonly by Anisakis simplex. Acquired by the consumption of raw or undercooked marine fish or squid, anisakidosis occurs where such dietary customs are practiced, including Japan, the coastal regions of Europe and the United States. Rupture of the spleen is a relatively common complication of trauma and many systemic disorders affecting the reticuloendothelial system, including infections and neoplasias. A rare subtype of rupture occurring spontaneously and arising from a normal spleen has been recognized as a distinct clinicopathologic entity. Herein we discuss the case of a woman who presented to our institution with appendicitis secondary to Anisakis and spontaneous spleen rupture. We report the case of a 53-year-old Caucasian woman who presented with hemorrhagic shock and abdominal pain and was subsequently found to have spontaneous spleen rupture and appendicitis secondary to Anisakis simplex. She underwent open

Recently, copy number alteration (CNA) of 9p24.1 were demonstrated in 10% of diffuse large b-cell lymphoma (DLBCL), with gene expression and mutation profiles that were similar to those of primary mediastinal large B-cell lymphoma (PMBCL). However, their CNA-based profile and clinical impact still remain unclear. Multiplex ligation-dependent probe amplification were employed to investigate the prevalence of JAK2/PD-L2 amplification in DLBCL and their CNA-based pattern of driver genes. The clinical outcome and characteristics were also analyzed. Using unsupervised hierarchical clustering, a small group of DLBCL (10.5%, 8/76) was clustered together with PMBCL as Cluster_2, demonstrating amplification of JAK2 (100%,8/8) and PD-L2 (75.0%,6/8). This subgroups of DLBCL demonstrated significant higher expression of PD-L1 than those with MYD88 L265P mutation(p = 0.024). And they exhibited dismal OS and PFS as compared with DLBCL_others(p = 0.003 and 0.001, respectively), which is similar to DLBCL with MYD88

Its tendency to target young adults makes its social impact particularly significant; hence, the General Practitioner carries the responsibility for an early diagnosis. On the contrary, the extreme complexity of the available therapies makes a quick referral to specialized Clinical Centres of outmost importance, since this remains the best way to enrol as many patients as possible in therapeutic protocols. Nowadays, good clinical results and a favourable outcome are achievable, but some questions remain open. The role of radiotherapy still has to be clarified, both as a complete ...

Yogi Berra offered the comment Its déjà vu all over again when he witnessed Mickey Mantle and Roger Maris repeatedly hitting back-to-back home runs in the early 1960s. His pithy remark neatly summarizes my reaction when I read the article, Dose-Adjusted EPOCH-Rituximab Therapy in Primary Mediastinal B-Cell Lymphoma, by Drs. Dunleavy, Wilson, and colleagues in The New England Journal of Medicine.1. The report nicely caps more than a decade of clinical investigation carried out by Dr. Wilsons group at the National Cancer Institute, focused on the use of infusional immunochemotherapy to treat various aggressive non-Hodgkin lymphomas (see a summary of the report in this issue of The ASCO Post). Briefly, this group demonstrated that when they used dose-adjusted EPOCH-R (etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, and rituximab [Rituxan]) to treat primary mediastinal large B-cell lymphoma in 51 patients, almost all of the patients appeared to have been cured. ...

In October 2016, at the age of 21, I was diagnosed with primary mediastinal large B-cell non-Hodgkins lymphoma. After a few weeks of chest pains, finding a lump on my chest which led to many tests, I was admitted to Cincinnati Childrens Hospital where I received treatment.

Etiology: Malignant lymphomas arise from lymphocytes and their precursors. They can be categorized into seven types. Small lymphocyte, lymphoblastic, pleomorphic/follicular, plasmacytic, immunoblastic, marginal zone and not otherwise specified (NOS).. Incidence: Malignant lymphomas are common in certain strains/stocks of mice.. Clinical Signs: Often there are no clinical signs associated with lymphoma.. Pathology: Malignant lymphomas are usually systemic tumors, and are most common in the mesenteric lymph nodes and spleen. Grossly, the spleen and mesenteric lymph node are enlarged and may have tan discoloration (picture). There may be liver or multiple lymph node involvement in more advanced cases. Histologically, tumor features are dependent on the type of lymphoma [1].. Diagnosis: Diagnosis can be made upon necropsy and histopathologic examination of tissue.. ...

Patients often present with an advanced stage of disease and highly malignant subtypes including BURKITT LYMPHOMA; IMMUNOBLASTIC LARGE-CELL LYMPHOMA; PRIMARY EFFUSION LYMPHOMA; and DIFFUSE, LARGE B-CELL, LYMPHOMA. The tumors are often disseminated in unusual extranodal sites and chromosomal abnormalities are frequently present. It is likely that polyclonal B-cell lymphoproliferation in AIDS is a complex result of EBV infection, HIV antigenic stimulation, and T-cell-dependent HIV activation ...

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging hemorrhagic fever caused by a tick-borne banyangvirus and is associated with high fatality. Despite increasing incidence of SFTS and serious public health concerns in East Asia, the pathogenesis of lethal SFTS virus (SFTSV) infection in humans is not fully understood. Numbers of postmortem examinations to determine target cells of the viral infection have so far been limited. Here we showed that B cells differentiating into plasmablasts and macrophages in secondary lymphoid organs were targets for SFTSV at the end stage of lethal infection, and the majority of SFTSV-infected cells were B cell-lineage lymphocytes. In affected individuals, B cell-lineage lymphocytes with SFTSV infection were widely distributed in both lymphoid and nonlymphoid organs, and infiltration of these cells into the capillaries of the organs could be observed occasionally. Moreover, a human plasmablastic lymphoma cell line, PBL-1, was susceptible to SFTSV ...
