Follicular helper T-cell (TFH) lymphomas comprise a unique group of that represent neoplastic proliferations follicular T-cells and share genetic, immunophenotypic, morphologic, clinical features. Angioimmunoblastic lymphoma (AITL) is the prototypical TFH lymphoma; in addition, 2017 revised World Health Organization (WHO) 4th edition recognizes two other subtypes: (FTCL) nodal peripheral with T...
Cutaneous T-cell lymphoma describes a heterogeneous group of neoplasms of skin homing T cells that vary considerably in clinical presentation, histologic appearance, immunophenotype, and prognosis. This paper addresses the cutaneous T-cell lymphoma in Asians with respect to clinical-epidemiologic and histopathological features. Compared with Western countries, Asia usually has higher rates of c...
Breast is an uncommon site of extra nodal lymphoma accounting for 2.2% all lymphomas. B cell lymphomas are more common than T types. The most subtype Diffuse Large Cell Lymphoma. very challenging to diagnose as it has nonspecific clinical and radiological features. We report a rare case primary in 20-year-old female. It was misdiagnosed abscess on ultrasound suppurative mastitis fine needle asp...
background and objectives: epstein barr virus (ebv) is one of the members of herpesviridae family and a sub-category of gamma herpes virinae. ebv, which normally has cr2 or cd21 receptors on b-lymphocytes, has mutagenic features for them. the virus plays an important role in causing some malignant cancers. about 30% of the cases with non-hodgkin’s lymphoma are diffuse large b-cell lymphoma (dlb...
Clinical trials of immunotherapy in mantle cell lymphoma have not yet delivered desirable results, partly because of the inhibitory machinery of the tumor and its microenvironment. Here we investigated the role of B7-H1, a member of the B7 family of co-stimulatory/co-inhibitory ligands, in mantle cell lymphoma-mediated immunosuppression. Allogeneic CD3(+), CD4(+) and CD8(+) T cells were purifie...
Clonal chromosome abnormalities were found in 89 (97%) of 92 patients with non-Hodgkin's malignant lymphoma including immunologically determined 34 B- and 25 T-lymphomas; only 3 of 19 T-lymphoma patients examined had serum adult T-cell leukemia/lymphoma-associated antigen antibody. Association of 8q24 translocations with small non-cleaved cell (P less than 0.01) and that of t(14;18) (q32;q21) w...
Background: Previous studies have pointed to the major role of viruses in pathogenesis cancers, especially lymphoproliferative cancers. Objectives: The current study investigated relationship between recent Human Herpesvirus Type 6 (HHV6) infection and childhood leukemia-lymphoma syndrome. Methods: From January 2011 December 2012, we entered every new case acute lymphoblastic leukemia, non-Hodg...
