Gray zone lymphoma (GZL) is described as sharing features with classical Hodgkin lymphoma (cHL) and diffuse large B-cell lymphoma (DLBCL). However, there remains complexity in establishing diagnosis, delineating prognosis, and determining optimum therapy. Sixty-eight cases diagnosed as GZL across 15 North American academic centers were evaluated by central pathology review to achieve consensus. Of these, only 26 (38%) were confirmed as GZL. Morphology was critical to GZL consensus diagnosis (eg, tumor cell richness); immunohistochemistry showed universal B-cell derivation, frequent CD30 expression, and rare Epstein-Barr virus (EBV) positivity (CD20+, 83%; PAX5+, 100%; BCL6+, 20%; MUM1+, 100%; CD30+, 92%; EBV+, 4%)...

High-dose therapy (HDT) and autologous hematopoietic cell transplantation (auto-HCT) has been anecdotally prescribed in gray zone lymphoma (GZL), showing encouraging efficacy. We conducted a multicenter retrospective study aimed to assess outcomes after auto-HCT in 32 patients with GZL treated at 9 transplant centers in the United States. Median age of patients at transplantation was 38 (18-70) years and the majority were male (n=21, 66%). Median number of lines of therapy prior to transplantation was 2 (1-4)...

Primary mediastinal B-cell lymphoma (PMBCL) is recognized as a distinct clinicopathologic entity that predominantly affects adolescents and young adults and is more common in female subjects. Although PMBCL is considered to be a subtype of diffuse large B-cell lymphoma, its clinical, morphologic, and biological characteristics overlap significantly with those of nodular sclerosing Hodgkin lymphoma (NSHL). Over the past few years, the shared biology of these 2 entities has been highlighted in several studies, and mediastinal gray zone lymphoma, with features intermediate between PMBCL and NSHL, has been recognized as a unique molecular entity...

AIMS: Mediastinal gray zone lymphoma (MGZL) is a rare entity with morphologic, immunophenotypic, and genetic features intermediate between classic Hodgkin lymphoma (CHL) and primary mediastinal large B-cell lymphoma (PMBL). It is challenging to differentiate from CHL and PMBL. A specific dendritic cell gene expression profile can distinguish CHL and MGZL from PMBL. We hypothesized that the dendritic markers fascin and CD123 may be helpful in distinguishing MGZL from CHL and PMBL. We also investigated programmed death-ligand 1 (PD-L1) expression in MGZL, which may have therapeutic significance in this difficulty to treat tumor...

The 2016 revision of the World Health Organization (WHO) classification of lymphoid neoplasms have been published in "Blood" as a review form. A major revision is being published that will be an update of the current fourth edition and not a truly new fifth edition. Because it is considered a part of the fourth edition, while some provisional entities will be promoted to definite entities and a small number of new provisional entities added, there will be no new definite entities. As with the 2001 and 2008 classifications, an all-important Clinical Advisory Committee meeting was held to obtain the advice and consent of clinical hematologists/oncologists and other physicians critical to the revision...

BACKGROUND: Classic Hodgkin lymphoma (CHL) and nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) are clinically distinct entities, with different prognostic and treatment implications. In addition, several large B-cell lymphomas and some T-cell lymphomas can mimic CHL. Differentiating these entities from CHL is crucial for ensuring appropriate therapy. GATA3 is a T-cell transcription factor involved in T-cell maturation and has been previously shown to be overexpressed in CHL cells via gene expression profiling...

Monoamine oxidase A (MAOA) is a mitochondrial enzyme that catalyzes oxidative deamination of neurotransmitters and dietary amines and produces H2 O2 . It facilitates the progression of gliomas and prostate cancer, but its expression and functional relevance have not been studied in lymphoma. Here, we evaluated MAOA in 427 cases of Hodgkin and non-Hodgkin lymphoma and in a spectrum of reactive lymphoid tissues by immunohistochemistry on formalin-fixed, paraffin-embedded specimens. MAOA was expressed by Hodgkin Reed-Sternberg (HRS) cells in the majority of classical Hodgkin lymphomas (cHLs) (181/241; 75%), with 34...

Primary mediastinal B-cell lymphoma is a distinct clinicopathologic entity that has a predilection for young women. It is clinically and molecularly different from other subtypes of diffuse large B-cell lymphoma and has a unique paradigm of management. While the cure rate for patients with primary mediastinal B-cell lymphoma is high, approaches have historically included mediastinal radiation; in moving therapeutics forward, strategies that obviate the need for radiation while maintaining high cure rates are critical...

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)...
