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...

A small percentage of nodular lymphocytic predominant Hodgkin lymphoma (NLPHL) progresses to diffuse large B-cell lymphoma (DLBCL). There have also been rare reports of gray zone lymphoma with features intermediate between classical Hodgkin lymphoma (CHL) and DLBCL. We report a very rare case of composite lymphoma (CHL and NLPHL) progressing to DLBCL, and highlight the diagnostic difficulty faced during its fine-needle aspiration (FNA) cytology diagnosis. A 65-year-old woman presented with a right axillary swelling which was subjected to FNA cytology...

BACKGROUND: Mediastinal gray zone lymphoma (MGZL) shares clinical characteristics with primary mediastinal B-cell lymphoma (PMBCL) and nodular sclerosing Hodgkin lymphoma (NSHL). However, MGZL is extremely rare, and an appropriate treatment for it has not yet been established. METHODS: We retrospectively analyzed 8 patients who were treated with systemic chemotherapy for MGZL between 2007 and 2014. RESULTS: The patients with MGZL were predominantly young and male (median age 26 years), and 62...

Primary mediastinal large B-cell lymphoma (PMBL) is a distinct subtype of diffuse large B-cell lymphoma (DLBCL) that shows overlap with classical Hodgkin lymphoma (CHL) and a favorable prognosis compared to mediastinal gray-zone lymphoma (MGZL). We performed immunohistochemistry on initial diagnostic specimens of 49 cases of uniformly treated PMBL to determine the frequency and clinical significance of expression of antigens commonly seen in CHL and MGZL, along with markers previously shown to be prognostic in DLBCL, not otherwise specified...

Primary mediastinal B-cell lymphoma (PMBL) is an entity of B-cell lymphoma distinct from the other molecular subtypes of diffuse large B-cell lymphoma (DLBCL). We investigated the prevalence, specificity, and clinical relevance of mutations of XPO1, which encodes a member of the karyopherin-β nuclear transporters, in a large cohort of PMBL. PMBL cases defined histologically or by gene expression profiling (GEP) were sequenced and the XPO1 mutational status was correlated to genetic and clinical characteristics...

Extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) is a distinct lymphoma with specific clinical and pathological features that occurs in diverse anatomic locations. We conducted this retrospective study to demonstrate our experience in patients with MALT lymphomas and compare our results with the literature. We studied 23 patients with histologically confirmed diagnosis of MALT lymphomas (12 with gastric, 11 with non-gastric localization) treated during the past 13 years. The female/male ratio of patients was 15/8 with a median age at presentation of 56 years (range 27-88 years)...

A 50-year-old male presented with cough and breathlessness. A positron emissoin tomography scan revealed FDG (Fluorodeoxyglucose) avid mediastinal mass. Tru-cut biopsy showed fibrotic stromal tissue with cellular infiltrate consisting of abnormal lymphoid cells and few large cells with smudged nucleus. Immunohistochemistry revealed diffuse positivity with CD20, focal positivity for CD30 and rare CD15 positive cells. Histological picture and immune profile showed overlaping features of non-Hodgkin's as well as Hodgkin's lymphoma...

Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphoma (DLBCL) of the elderly is a provisional entity included in the 2008 WHO classification of lymphoid neoplasms. It is a disease typically seen in the elderly and thought to be associated with chronic EBV infection and severe immunosuppression with a component of immunosenescence. Recent research, however, has suggested that EBV-positive DLBCL can be seen in younger, immunocompetent patients. The diagnosis of EBV-positive DLBCL of the elderly is made through a careful pathological evaluation...

Activation of the programmed death 1 (PD1)/PD1 ligand (PDL1) pathway is important for tumor cells to escape from immune control. The clinical efficacy of therapeutic modulation of the PD1-PDL1 pathway has been recently shown in classical Hodgkin lymphoma (cHL), but little is known about the frequency and diagnostic and prognostic importance of PDL1 expression in lymphomas. The available anti-PDL1 antibody clones E1L3N and SP142 were compared, and a large cohort of Hodgkin lymphomas (n=280) and B-cell lymphomas (n=619) was examined for PDL1 using E1L3N...

AIM: To identify aggressively behaving classical Hodgkin lymphoma (CHL) of mediastinum and primary mediastinal B-cell lymphoma (PMBCL) and to classify them as mediastinal gray zone lymphoma(MGZL) and to define a minimum immunopanel for the diagnosis of MGZL. MATERIALS AND METHODS: Ninety-two mediastinal B-cell lymphomas were reviewed with a wide immunopanel and were classified as CHL, PMBCL, or MGZL. CHL with an expression of 3 or 4 transcription factors performed worse, and hence the CHL with ≥3 transcription factors were classified as MGZL-CHL...

Although primary mediastinal large B-cell lymphoma and classic Hodgkin lymphoma of nodular sclerosis type are distinct disease, they share several clinical characteristics and biologic features. However, there are mediastinal lymphomas that not fit in either category. These types of lymphomas are recognized as mediastinal gray zone lymphomas. Gray zone lymphomas are lymphatic tumors that cannot be assigned to a defined lymphoma entity due to morphological, clinical, or genetic reasons. In this report, we present a case of a 22 year-old-Hispanic-female diagnosed with B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and Hodgkin lymphoma...

Double-hit lymphomas (DHL) are defined as B-cell lymphoma with a chromosomal breakpoint affecting the MYC/8q24 locus in combination with rearrangement at (14;18)(q32;q21). We recently observed three cases of B-cell lymphoma with an extra intact MYC signal in association with the t(14;18)(q32;q21) translocation. The impact of an extra copy of MYC to the clinical course and prognosis of one patient with Diffuse Large B Cell Lymphoma (DLBCL) and two patients with Follicular Lymphoma (FL) was evaluated. Flow cytometry in all cases demonstrated lambda- or kappa-light chain restricted CD20 and CD10 positive neoplastic B cells...

BACKGROUND: The diagnosis of "B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and classical Hodgkin lymphoma" represents an indeterminate or equivocal decision in relation to management because there remain differences in the management of Hodgkin and non-Hodgkin lymphomas. We developed a scoring system for this group of lymphomas using markers that are traditionally associated with diagnosis of classical Hodgkin lymphoma (CHL) and immunophenotypic markers associated with the "B-cell program" expressed in normal B cells...

B cell lymphoma, unclassifiable, with features of diffuse large B cell lymphoma and classical Hodgkin's lymphoma (BCLu-DLBCL/CHL) is more commonly known as gray zone lymphoma. These cases more often present with mediastinal disease. In this report, we present a very rare case of BCLu-DLBCL/CHL without mediastinal involvement, transformed from follicular lymphoma (FL) to BCLu-DLBCL/CHL. This patient initially presented with a mass in the right neck; biopsy of the lymph node showed predominantly nodular, follicular pattern...

Mediastinal involvement is considered essential for the diagnosis of primary mediastinal large B-cell lymphoma (PMBL). However, we have observed cases of diffuse large B-cell lymphoma (DLBCL) with features of PMBL but without detectable mediastinal involvement. The goal was to assess our previously established gene expression profiling (GEP) signature for PMBL in classifying these cases. In a large series of DLBCL cases, we identified 24 cases with a GEP signature of PMBL, including 9 cases with a submission diagnosis of DLBCL consistent with PMBL (G-PMBL-P) and 15 cases with a submission diagnosis of DLBCL...

Gray zone lymphoma (GZL) with features between classical Hodgkin lymphoma and diffuse large B-cell lymphoma (DLBCL) is a recently recognized entity reported to present primarily with mediastinal disease (MGZL). We examined detailed clinical features, outcomes, and prognostic factors among 112 GZL patients recently treated across 19 North American centers. Forty-three percent of patients presented with MGZL, whereas 57% had non-MGZL (NMGZL). NMGZL patients were older (50 versus 37 years, P = 0.0001); more often had bone marrow involvement (19% versus 0%, P = 0...

Few studies have reported Epstein-Barr virus-positive (EBV(+)) large B-cell lymphomas (LBCLs) in young patients without immunodeficiency. We identified 46 such cases in patients ≤45 years of age and analyzed the clinical and pathological characteristics. EBV(+) LBCLs affected predominantly males (male:female = 3.6:1), with a median age of 23 years (range, 4-45 years). All patients presented with lymphadenopathy and 11% also had extranodal disease. Morphologically, 3 patterns were identified: T-cell/histiocyte-rich large B-cell lymphoma-like (n = 36), gray zone lymphoma (n = 7), and diffuse LBCL-not otherwise specified (n = 3)...
