BACKGROUND It has generally been proven that histone acetylation and deacetylation are involved in the malignant transformation. To date, however, this has rarely been studied in cases of malignant lymphoma. METHODS We studied nine cases of reactive lymphoid hyperplasia, 78 cases of diffuse large B-cell lymphoma (DLBCL), 13 cases of peripheral T-cell lymphoma, not otherwise specified (PTCL-NO...
OBJECTIVE To determine the effect of closure or non-closure of the visceral peritoneum at cesarean delivery on uterine scar formation assessed at repeat cesarean delivery. METHODS Women undergoing initial cesarean delivery were allocated into 2 groups: group 1 underwent visceral peritoneal closure, while in group 2 the visceral peritoneum was not closed. At repeat cesarean delivery 4 specimen...
Reactive Lymphoid Hyperplasia of the Liver Mimicking Liver Metastasis in a Patient with Cecal Cancer
We report here a case of idiopathic CD4(+) T-lymphocytopenia (ICL) associated with Epstein-Barr virus (EBV)(+) lymphoproliferative disorder (LPD) terminating in Burkitt lymphoma (BL). A 33-year-old Japanese male was admitted to the hospital showing severe CD4(+) lymphocytopenia and neutropenia that was diagnosed as ICL in 1993. Twenty months after the onset of disease, right cervical lymphadeno...
One of the earliest events in the pathogenesis of systemic sclerosis (SSc) is microvasculature damage with intimal hyperplasia and accumulation of cells expressing PDGF receptor. Stimulatory autoantibodies targeting PDGF receptor have been detected in SSc patients and demonstrated to induce fibrosis in vivo and convert in vitro normal fibroblasts into SSc-like cells. Since there is no evidence ...
AIMS To study the value of wide needle (19 gauge) aspiration cytology in the diagnosis of lymph node disease in Zambia in the absence of a trained cytologist. METHODS Patients (n = 304) referred for surgical biopsy of an enlarged peripheral lymph node were studied prospectively. Surgical biopsy was routinely preceded by 19 gauge needle aspiration of the same node; aspirates were stained by ha...
Angioimmunoblastic T-cell lymphoma (AITL) is a systemic disease involving lymph nodes, spleen, and bone marrow. Although the histologic features have been well described, the diagnosis is often challenging, as there are no specific phenotypic or molecular markers available. This study shows that the neoplastic cells of AITL can be identified by aberrant CD10 expression. Archival material from 3...
Type II diabetes mellitus (DM) and metabolic syndrome are associated with accelerated restenosis following vascular interventions due to neointimal hyperplasia. The efficacy of nitric oxide (NO)-based therapies is unknown in these environments. Therefore, the aim of this study is to examine the efficacy of NO in preventing neointimal hyperplasia in animal models of type II DM and metabolic synd...
