After infections, malignancies, lymphomas especially, are the second most frequent cause of death in patients with inborn errors immunity. Factors predetermining appearance and aggressiveness include gene defects, defects immune surveillance regulation as well infections oncogenic viruses. Aggressive non-Hodgkin lymphomas, mostly diffuse large B-cell Bukit subtypes predominant deoxyribonucleic ...
Introduction: Several reports have been made associating dupilumab therapy for atopic dermatitis (AD) with the development of mycosis fungoides (MF) and other cutaneous T cell lymphomas (CTCL)
OBJECTIVE To observe the spectrum of non-Hodgkin's lymphomas involving the central nervous system including morphological subtypes and immunophenotypic status. SETTING Retrospective analysis of eleven years (1986 to 1996) data from surgical pathology files of Department of Pathology. RESULTS Forty-three cases of non-Hodgkin's lymphomas were diagnosed during the period of eleven years (from ...
Recent studies have suggested a probable association between Epstein-Barr virus (EBV) and nasal/nasopharyngeal T cell lymphomas but the role of oncogenes or tumor suppressor genes is poorly understood. We have studied the frequency of p53 expression and its relation to the EBV infection in 33 Korean patients with head and neck (H&N) lymphomas. All cases (23 B cell & 10 T cell) were immunostaine...
background plasmablastic lymphoma (pbl) is a relatively new entity, classified by who as a rare variant of diffuse large b cell lymphoma. the present case report introduces a 17 year old girl with chronic diarrhea, abdominal pain, intra-abdominal venous thromboses, ascites, mesenteric lymphadenopathies and small intestinal polyposis, the pathologic and immunohistochemistric examinations of the ...
Primary breast lymphoma represents less than 1% of all primary breast malignancies and most primary breast lymphomas are of B-Cell origin. The association of anaplastic lymphoma kinase (ALK) negative anaplastic large cell lymphoma (ALCL), a very rare form of primary breast lymphoma, with silicone-filled breast implants has been suggested and several case reports supported this proposal, especia...
Epstein-Barr virus(EBV) has been implicated in the pathogenesis of B-lymphoproliferative disorders, T-cell lymphomas and Hodgkin's disease. In this report, we performed an in situ hybridization study on EBV genome in 10 cases of nasal non-Hodgkin's lymphoma(NHL), 20 cases of Waldeyer's ring(WR) NHL, and 20 cases of nodal NHLs to document EBV association with lymphomas in Koreans. For immunophen...
Immunosuppressed individuals are at high risk for the development of hematologic malignancies. The typical lymphomas arising in organ transplant recipients are B-cell non-Hodgkin's lymphomas that contain Epstein-Barr virus (EBV) DNA sequences. We investigated the characteristics of posttransplant lymphomas that lacked expression of the usual markers associated with EBV transformation. We descri...
BACKGROUND T follicular helper (T(FH)) cells reside in the light zone of germinal centers and are considered the cell of origin of angioimmunoblastic T-cell lymphoma. Recently, CXCL13, PD-1 and SAP were described as useful markers for T(FH) cells and angioimmunoblastic T-cell lymphoma but also reported in some peripheral T-cell lymphomas, not otherwise specified. DESIGN AND METHODS In the pre...
