Background: Age and performance status are important prognostic factors in primary central nervous system (CNS) lymphoma. Although several prognostic models have been proposed, there is no consensus on the optimal model for patients with diffuse large B-cell histology. Methods: Seventy-seven patients with primary CNS diffuse large B-cell lymphoma were retrospectively analyzed to determine factors affecting survival. Three Western models were applied to our eligible patients; we devised a novel model based on our findings...

Primary extra nodal lymphomatous involvement of the genitourinary tract is rare and secondary extra-nodal involvement in disseminated disease occurs more frequently. Imaging of metabolic activity with 2-[fluorine-18] fluoro-2-deoxy-d-glucose (FDG) used in positron emission tomography (PET) facilitates the identification of these extra-nodal sites of disease, particularly in the absence of structural lesions on conventional imaging modalities. Primary extra-nodal lymphoma affecting the genitourinary system is often caused by high-grade Non-Hodgkin's Lymphoma (NHL) with the most common subtype being Diffuse Large B-Cell Lymphoma (DLBCL)...

Patients with mycosis fungoides (MF), the most common subtype of primary cutaneous T-cell lymphoma, have an increased risk of developing secondary malignancies. We herein report two rare cases of MF concurring with diffuse large B cell lymphoma (B lymphoid lineage) and acute myeloid leukemia (myeloid lineage) in two otherwise healthy elderly patients. Potential etiologic factors, including the impact of the therapy-associated inflammatory response on the development of secondary tumors in patients with MF, are discussed...

A collision tumor is defined as two histologically distinct tumor types identified at the same anatomic site. Hematolymphoid proliferative disorders (HLPDs), which coincide with non-hematological neoplasms, can mimic an immune response and can easily be overlooked as an immune reaction to a solid organ neoplasm, especially when low grade. In order to avoid a delay in the diagnosis of a HLPD during the workup for a non-hematological neoplasm, we identified a cohort of 100 cases with a HLPD diagnosis during the initial workup and treatment of a non-hematological neoplasm, or vice versa...

Double-hit lymphoma (DHL) is defined as lymphoma with concurrent BCL2 and MYC translocations. While the most common histological subtype of DHL is diffuse large B-cell lymphoma, the present patient had leukemic follicular lymphoma (FL). A 52-year-old man was admitted to our hospital due to general fatigue and cervical and inguinal lymph node swelling. The patient was leukemic and the pathological diagnosis of the inguinal lymph node was FL grade 1. Chromosomal analysis revealed a complex karyotype including a rare three-way translocation t(8;14;18)(q24;q32;q21) involving the BCL2, MYC, and IGH genes...

The spectrum of bone marrow lesions in patients with nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) has not been evaluated systematically. In this study, we analyzed a cohort of 262 NLPHL patients who underwent staging bone marrow evaluation or targeted bone biopsy as a part of their initial diagnostic workup, among which lymphoma was detected in 24 (9.2%) patients. Eleven patients had bone marrow findings of NLPHL (few large B cells in a background of small B cell and T cell), and 13 patients had either T-cell/histiocyte-rich large B-cell lymphoma (large B cells in a background of T cells and histiocytes) or typical diffuse large B-cell lymphoma (sheets of large B cells)...

Myocyte enhancer binding factor 2B (MEF2B) is a transcriptional activator of the BCL6 proto-oncogene in normal germinal center (GC) B-cells. Limited data exists concerning its expression in B-cell lymphomas, and comparison with other GC-associated antigens is lacking. Its role in the differential diagnosis of B-cell lymphomas, particularly in the distinction of follicular lymphoma (FL) versus marginal zone lymphoma (MZL), remains to be determined. We evaluated MEF2B expression, in comparison with additional GC markers, LIM domain-only transcription factor 2 (LMO2), and human GC-associated lymphoma (HGAL), in a variety of B-cell lymphomas, with particular emphasis on their utility in differentiating FL from MZL...
