Tumor necrosis factor-α-inducible protein-2 (TNFAIP2) is a protein upregulated in cultured cells treated with tumor necrosis factor α (TNF), but its expression in normal and neoplastic tissues remains largely unknown. Here, we use standard immunohistochemical techniques to demonstrate that TNFAIP2 is normally expressed by follicular dendritic cells, interdigitating dendritic cells, and macropha...

OBJECTIVES To evaluate efficacy, patient tolerance, and adverse effects of CyberKnife radiosurgery for the treatment of intraocular and periocular lymphoma. METHODS Retrospective case series of 13 patients who underwent CyberKnife radiosurgery was conducted. RESULTS Fourteen eyes of 13 patients were included. The tissue location of the lymphoma was orbit (7 eyes), conjunctiva (3 eyes), chor...

Peritoneal lymphomatosis is an extremely rare presentation of lymphoma. Due to its relative low frequency, it receives much less attention than peritoneal carcinomatosis. The challenge is to differentiate between lymphomatosis and carcinomatosis, as well as peritoneal tuberculosis or other pathologic entities within the peritoneal cavity based essentially on radiologic features. 18</...

background: the incidence rate of breast cancer has been dramatically increasing since the last decade in iran, and it is now one of the most common female malignant tumors. b?cell lymphoma 2 (bcl2) family is the most important regulator of apoptosis, and ?938c>a single nucleotide polymorphism (snp) of bcl2 gene promoter has been demonstrated to influence breast cancer susceptibility. in this r...

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...

Abstract B-cell lymphoblastic lymphoma (B-LBL) is an uncommon subtype of pediatric non-Hodgkin Lymphoma (NHL) which rarely involves the skin primarily. The positron emission tomography with 2-deoxy-2-[fluorine- 18] fluoro-D: -glucose integrated with computed tomography (18F-FDG PET/CT) scan findings of a 8-year-old boy with cutaneous B-LBL were presented. PET/CT scan demonstrated mild FDG up...

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 ...
