Chee Leong Cheng, Simon O'Connor
Accurate diagnostic interpretation of a lymphoid population composed predominantly of small T cells, together with smaller numbers of large B cells, with or without a nodular architecture, is a common problem faced by the histopathologist. The differential diagnosis of this histological pattern is wide, ranging from reactive conditions such as drug reactions and viral infections, through borderline entities such as immunodeficiency-related lymphoproliferative disorders to lymphomas. The latter includes entities where the large B cells are primarily neoplastic (classical and nodular lymphocyte-predominant Hodgkin lymphomas and T cell/histiocyte-rich large B cell lymphoma) as well as T cell lymphomas such as angioimmunoblastic T cell lymphoma where the large B cells represent an epiphenomenon and may or may not be neoplastic...

Nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) presents different histopathologic growth patterns, including atypical forms showing overlapping histopathologic and clinical features with T cell/histiocyte rich large B cell lymphoma (THRLBCL). As growth patterns are associated with vessel distribution, the aim of the present study was to compare angiogenesis in different NLPHL patterns with THRLBCL as well as other lymphomas. Atypical variants of NLPHL and THRLBCL (n=10 per group) both showed a low microvessel density (MVD, 1...

Diffuse large B-cell lymphoma (DLBCL) is the most common type of lymphoma worldwide. The current World Health Organization classification includes several subtypes based on a combination of clinical, immunohistochemical, and genetic differences. Other aggressive variants of B-cell lymphomas, including Burkitt lymphoma and double-hit lymphomas are part of the differential diagnosis and often have overlapping features with DLBCL. In this study, we evaluated 760 of cases of DLBCL and other aggressive B-cell lymphomas using a relatively uniform immunohistochemical panel and genetic methods...

T-cell/histiocyte-rich large B-cell lymphoma is an unusually encountered lymphoid neoplasm of stomach with aggressive course, and is an uncommon morphologic variant of diffuse large B-cell lymphoma. An ulcerated mass, 7x5x1 cm in size was observed within the gastrectomy specimen of a 76-year-old female patient. In cross sections, besides mature lymphoid cells displaying T-cell phenotype, a neoplastic formation composed of large, pleomorphic atypical lymphoid cells with, prominent nucleoli, vesicular nuclei and abundant eosinophilic cytoplasm displaying B-cell phenotype were observed...

Diffuse large B-cell lymphoma (DLBCL) is an aggressive disease with considerable heterogeneity reflected in the 2008 World Health Organization classification. In recent years, genome-wide assessment of genetic and epigenetic alterations has shed light upon distinct molecular subsets linked to dysregulation of specific genes or pathways. Besides fostering our knowledge regarding the molecular complexity of DLBCL types, these studies have unraveled previously unappreciated genetic lesions, which may be exploited for prognostic and therapeutic purposes...

BACKGROUND: Diffuse large B-cell lymphoma is the most common subtype of non-Hodgkin's lymphoma. Standard first-line treatment for this aggressive subtype comprises the anti-CD20 antibody rituximab combined with cyclophosphamide, doxorubicin, vincristine, and prednisone. If patients receiving such treatment have an early relapse, or their disease is initially refractory to such treatment, standard salvage regimens may not be effective. There is therefore a high unmet clinical need for new targeted agents that might improve the outcome for such patients...

T cell/histiocyte-rich large B cell lymphoma (THRLBCL) is predominantly a nodal disease, with extranodal involvement, such as bone marrow, spleen, and liver. However, primary THRLBCL has never been reported in the thymus in the English literature. Here we report a case of THRLBCL presenting as mediastinal mass and lymphadenopathy. Based on the frozen section diagnosis of "thymoma," a 12 cm mass was excised. A year later she developed multiple enlarged lymph nodes and pulmonary nodules. Consultant review of the excised mediastinal mass showed scattered large atypical cells that were CD20+ and PAX-5+ and negative for pan-cytokeratin, AE1, and AE3, compatible with THRLBCL and excluding thymoma...

Primary central nervous system (PCNSL) lymphoma is an aggressive extranodal non-Hodgkin lymphoma, and most cases are classified as diffuse large B-cell lymphoma (DLBCL) by histology. T-cell/histiocyte-rich large B-cell lymphoma (TCRLBCL) represents a distinct subtype of diffuse large B-cell lymphoma and is characterized by the presence of scattered large neoplastic B-cells in a background of abundant T-cells and histiocytes. This is in contrast to the dense perivascular cuffing of neoplastic B-cells in classic DLBCL...

While tumor cells were the focus of research for many years, only recently have attempts been made to understand the role of the reactive bystander cells in malignant lymphomas. In certain types of lymphomas, such as Hodgkin lymphoma and T cell/histiocyte rich large B cell lymphoma, more than 90% of the infiltrate represent non-neoplastic cells, and these have important functions for the development and progression of the tumor. Among the bystander cells are histiocytes of particular importance, which vary largely in number, shape and quality among different patients...

Diffuse large B cell lymphoma (DLBCL) is a diffuse proliferation of large neoplastic B lymphoid cells with nuclear size equal to or exceeding that of normal macrophage nuclei. The DLBCL morphological variants are centroblastic, immunoblastic, T-cell- and histiocyte-rich, anaplastic, plasmablastic, anaplastic lymphoma kinase-positive, and primary mediastinal large B-cell lymphoma (PMBCL). These histopathologically-recognized morphological variants respond differently to treatment and have distinct prognoses...

BACKGROUND: Classical Hodgkin lymphoma (CHL), nodular lymphocyte predominant Hodgkin lymphoma (NLPHL), and T-cell/histiocyte rich large B-cell lymphoma (T/HRLBCL) are B-cell lymphomas in which tumor cells are rare as compared with the background reactive infiltrate. We hypothesized that characterization of the reactive infiltrates can provide information to help diagnose these lymphomas. METHODS: Lymphocyte subsets by flow cytometry were analyzed for 27 NLPHL, 20 T/HRLBCL, 34 CHL, and 49 reactive lymph nodes (RLN)...

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)...

Lymphomas may be induced by the systemic immunosuppressive therapies used to treat psoriasis, such as ciclosporin, methotrexate and tumour necrosis factor (TNF)-α blockers. The biologic agents currently used in psoriasis include alefacept, efalizumab, and the TNF-α antagonists etanercept, infliximab, and adalimumab. Infections and cancer are the main possible consequences of intended or unexpected immunosuppression. We report a 59-year-old man with a history of severe psoriasis vulgaris treated with traditional immunosuppressant drugs followed by anti-TNF-α therapy; the patient was firstly hospitalized for an acute cholestatic toxic hepatitis, which we supposed to be related to adalimumab...

BACKGROUND: Bone marrow biopsies are routinely performed for staging patients with B-cell non-Hodgkin lymphoma (NHL). In addition to histomorphological studies, ancillary tools may be needed for accurate diagnosis. We investigated the clinical utility of multiparameter flow cytometric examination of bone marrow aspirates. METHODS: A total of 248 bone marrow specimens from 232 patients diagnosed with B-cell NHL were examined. Monoclonal antibodies directed against CD19, CD20, CD10 (or CD5), and κ and λ immunoglobulins were used...

T-cell/histiocyte-rich large B-cell lymphoma (THRLBCL) is a distinct subtype of diffuse large B-cell lymphoma (DLBCL) under-recognized in the pediatric population. A meticulous workup is necessary to avoid a misdiagnosis of nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) or classical Hodgkin lymphoma (HL). A strong degree of suspicion and an emphasis on immunohistochemical staining are required to reach the diagnosis. Few children with advanced stage disease have been described to date. We report two pediatric patients with high stage THRLBCL and highlight their clinical and pathological features...

Nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) and T cell/histiocyte rich large B cell lymphoma (THRLBCL) usually affect middle-aged men, show tumour cells with a B cell phenotype and a low tumour cell content. Whereas the clinical behaviour of NLPHL is indolent, THRLBCL presents with advanced stage disease and an aggressive behaviour. In the present study, array comparative genomic hybridization was performed in seven typical NLPHL, four THRLBCL-like NLPHL variants, six THRLBCL and four diffuse large B cell lymphomas (DLBCL) derived from NLPHL...

In the spectrum of diffuse large B-cell lymphomas (DLBCL), both T-cell/histiocyte-rich large B-cell lymphoma (TCHRBCL) and most lymphomatoid granulomatosis (LG) cases are characterized by the relative rarity of the neoplastic B-cell population, with respect to the overwhelming non-neoplastic counterpart of T cells or histiocytes. Here we report a case of aggressive B-cell lymphoma with unusual clinicopathological features partially overlapping these two entities. The patient was a previously healthy 55-year-old male, presenting with a computed tomography finding of a pelvic mass, inguinal lymphadenopathies, and pulmonary nodules...

Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is characterized by nodular or nodular and diffuse growth of scattered large neoplastic B cells associated with follicular dendritic cell (FDC) meshworks. Variant patterns, which at least focally show a T-cell-rich background, and rare cases lacking FDC meshworks that overlap with T-cell/histiocyte-rich large B-cell lymphoma (THRLBCL) are also recognized. We reviewed 195 cases spanning the diagnostic spectrum of NLPHL and THRLBCL and identified 5 cases with distinctive features that were difficult to classify according to the World Health Organization criteria or previously described variants...
