The morphology of gray zone lymphoma (GZL) is variable with tumor cells spanning the spectrum of diffuse large B-cell lymphoma (DLBCL) and classical Hodgkin lymphoma. The immunophenotype is frequently discordant. Clinically, the initial case descriptions of GZL were primarily with mediastinal presentation; however, a nonmediastinal (systemic) clinical subtype is now recognized. Patients with GZL have high relapse rates. Recommended treatment of GZL is with a DLBCL-directed regimen with consideration for consolidative radiotherapy for bulk disease...

Myelin and lymphocyte (MAL) protein has been previously reported as a highly specific marker for distinguishing primary mediastinal large B-cell lymphoma (PMBL) from diffuse large B-cell lymphoma, not otherwise specified (DLBCL, NOS). However, there has not been a commercially available MAL antibody for immunohistochemistry. We identified a commercially available MAL monoclonal antibody and evaluated it by immunohistochemistry on 43 cases of PMBL and 63 cases of DLBCL, NOS. We also compared this with a CD200 antibody that was previously reported useful in distinguishing PMBL and DLBCL, NOS...

Lymphoma is one of the most frequent cancers in adolescent and young adults. Hodgkin Lymphoma is curable in more than 90% of cases. Recent pediatric and adults protocols aimed to decrease long term toxicities (mostly gonadic and cardiovascular) and secondary malignancies, reducing the use of alkylating agents and limiting radiation fields. Risk-adapted strategies, using positron emission tomography staging, are about to become a standard, both in adult and pediatric protocols. These approaches allow obtaining excellent results in adolescents with Hodgkin lymphoma...

Targeted immunotherapy based on PD-1/PD-L1 suppression has revolutionized the treatment of various solid tumors. A remarkable improvement has also been observed in the treatment of patients with refractory/relapsing classical Hodgkin lymphoma (cHL). We investigated PD-L1 status in a variety of treatment resistant lymphomas. Tumor samples from 78 patients with therapy resistant lymphomas were immunohistochemically (IHC) investigated for the expression of PD-L1 using two antibody clones (SP142 and SP263, Ventana)...

This is the first case series to describe primary mediastinal large B-cell lymphoma (PMLBL) patients in children and adolescents in Asia. We retrospectively identified 17 PMLBL patients diagnosed between 1991 and 2014; in seven of these cases, the diagnosis was confirmed by central review, representing 1.0% of all NHL and 2.2% of all B-NHL cases registered. All patients were teenagers, including seven adolescents, with a median age of 14 years (range 12-18 years). Ten patients were male, and seven were female...

We report a unique case of mediastinal grey zone lymphoma that was considered to originate from CD20(+)CD30(+) Hodgkin cell-like cells associated with a multilocular thymic cyst that had been completely removed 4 years previously. In the formerly resected thymus, irregular-shaped cysts were observed, and large CD20(+)CD30(+) Hodgkin cell-like cells proliferated in close association with the proliferating thymic epithelial cells. This case suggests the important role of thymic columnar epithelial cells in the proliferation of thymic B cells and the tumorigenesis of mediastinal grey zone lymphoma...

BACKGROUND: Primary mediastinal large B-cell lymphoma (PMBL) shares pathological features with diffuse large B-cell lymphoma (DLBCL), and molecular features with classical Hodgkin lymphoma (cHL). The miR-17~92 oncogenic cluster, located at chromosome 13q31, is a region that is amplified in DLBCL. METHODS: Here we compared the expression of each member of the miR-17~92 oncogenic cluster in samples from 40 PMBL patients versus 20 DLBCL and 20 cHL patients, and studied the target genes linked to deregulated miRNA in PMBL...

Primary mediastinal large B-cell lymphoma (PMLBCL) is one of the subtypes of diffuse large B-cell lymphoma. We experienced a rare case of PMLBCL that exhibited endobronchial involvement. A 33-year-old Japanese female with the chief complaints of epigastralgia, back pain, and nausea visited a primary care hospital. Computed tomography of the chest and abdomen demonstrated a bulky mass in the left anterior mediastinum, multiple pulmonary nodules, axillary lymph node swelling, and a pancreatic tumor. Fiberoptic bronchoscopy showed a white-tinged irregularly shaped endobronchial tumor accompanied by capillary vessel dilation in the left upper lobar bronchus...

Primary mediastinal large B-cell lymphoma (PMBL) is a lymphoma occurring in the anterior mediastinum starting from the cells B of the thymique medullary zone. This is a rare entity characterized by epidemiological, clinical and evolutionary peculiarities as well as by pathological and immunohistochemical peculiarities. We report a case series of 5 patients with diagnosed PMBL hospitalized in Pulmonology Department of Ibn Sina Hospital between January 2012 and May 2016. The average age was 34 years, the median of consultation time was 2 months...

This article aims to explain the current status of FDG-PET/CT in malignant lymphoma management by reviewing the new recommendations for evaluation, staging, and response assessment in patients with malignant lymphoma, published as the Lugano Classification in 2014. FDG-PET/CT was formally incorporated into standard staging for FDG-avid lymphoma in this new classification. Nearly all subtypes of malignant lymphoma are FDG-avid. In staging, the increased FDG uptake compatible with lymphoma is considered to represent involvement of lymphoma, regardless of size, and the FDG-avid lesion is potentially a good biopsy target...

Mediastinal grey zone lymphoma, B cell lymphomas with intermediate features between classical Hodgkin lymphoma and primary mediastinal B cell lymphoma, are not well described in the literature. We report the clinical characteristics and outcomes of a large retrospective series of 99 cases centrally reviewed by a panel of hematopathologists, with a consensus established for the diagnosis. Cases were defined as classical Hodgkin lymphoma-like morphology (64.6%) with primary mediastinal B cell lymphoma immunophenotype, primary mediastinal B cell lymphoma-like morphology (30...

Diffuse large B-cell lymphoma (DLBCL) accounts for 30-40% of all lymphoma subtypes. More than half of DLBCLs are estimated to arise from extranodal sites, and are called extranodal DLBCLs. Generally, the outcomes of extranodal DLBCL are not different from those of nodal DLBCL. To our knowledge, this report is the first to discuss the concept and the cell of origin of extranodal DLBCL, with the significance of the presence/absence of each involvement site in determining the outcome. Second, the evidence of clinical manifestation and outcomes of several extranodal DLBCLs requiring treatments other than R-CHOP, which is the current standard therapy for this malignancy, are discussed...

CD4 expression is rare in diffuse large B-cell lymphoma (DLBCL), with 4 previously reported cases. Its significance is uncertain. We report five patients with CD4(+) DLBCL and one CD4(+) primary mediastinal large B-cell lymphoma. Cases were identified by searching the electronic database of the department; each was reviewed. Average age was 56 years. Neoplastic cells expressed CD20 (5/6 tested cases). BCL2/BCL6 expression were seen in 3/3 tested cases, suggesting a germinal center origin. Additionally, expression of T-cell antigens CD2 and CD5 was noted in 2/2 and CD7 in 1/1 tested case...

We recently reported a truncating deletion in the NFKBIE gene, which encodes IκBϵ, a negative feedback regulator of NF-κB, in clinically aggressive chronic lymphocytic leukemia (CLL). Preliminary data indicate enrichment of NFKBIE aberrations in other lymphoid malignancies, hence we screened a large patient cohort (n=1460) diagnosed with different lymphoid neoplasms. While NFKBIE deletions were infrequent in follicular lymphoma, splenic marginal-zone lymphoma, and T-cell acute lymphoblastic leukemia (<2%), slightly higher frequencies were seen in diffuse large B-cell lymphoma, mantle cell lymphoma, and primary CNS lymphoma (3-4%)...

Lymphomas are one of the commonest malignancies in adolescents and young adults (AYA) accounting respectively for 22% of all cancers in patients aged 15-24 years (16% for Hodgkin lymphoma (HL) and 6% for non-HL (NHL)). The distribution of NHL subtypes in this age group differs strikingly from the distribution in children and in older adults with 4 main subtypes accounting for the majority of the cases: diffuse large B-cell lymphoma (DLBCL) including primary mediastinal B-cell lymphoma, Burkitt lymphoma, lymphoblastic lymphoma or anaplastic large cell lymphoma...

Primary mediastinal large B-cell lymphoma (PMLBL) is an uncommon non-Hodgkin lymphoma with a distinct clinicopathological entity in the WHO classification of lymphoid malignancies. It is known to originate from B-cells of the thymus. It mimics thymic neoplasms and other lymphomas clinically and histopathologically. We reported a 33-year-old obese man who presented with shortness of breath off and on for 4 years. Radiologically, there was a huge anterior mediastinal mass. Tru-cut biopsy was initially diagnosed as type-A thymoma...
