Hairy cell leukaemia (HCL) is a rare indolent B-cell lymphoproliferative disorder. We report diagnostic challenge in detecting the cause of ascites, which rare, unique manifestation HCL. A 72-year-old lady presented with 1-month-history pain left upper abdomen and loss weight. There was hepatomegaly, splenomegaly, bilateral inguinal lymphadenopathy, anaemia, lymphocytosis. She diagnosed as HCL,...
Autoimmune lymphoproliferative disorders, including autoimmune lymphoproliferative syndrome (ALPS) and Dianzani autoimmune lymphoproliferative disease (DALD), are inherited defects of the Fas apoptotic pathway characterized by lymphoid accumulation and autoimmune manifestations. We report the molecular, clinical, immunologic features and the long-term progress of 31 patients. Four carried Fas g...
non-hodgkin lymphoma (nhl) is one of the masquerade syndromes of malignant melanoma that can occur with two main patterns of presentations in the eye: metastatic involvement of uveal tract, and primary involvement of retina. we report ophthalmic, imaging and histopathological findings in the first case diagnosed as primary choroidal nhl without central nervous system or systemic involvement. a ...
B- and T-cell recirculation is crucial for the function of the immune system, with the control of cell migration being mainly mediated by several chemokines and their receptors. In this study, we investigated the expression and function of CXCR3 on normal and malignant B cells from 65 patients with chronic lymphoproliferative disorders (CLDs). Although CXCR3 is lacking on CD5(+) and CD5(-) B ce...
BACKGROUND Arsenic trioxide (As2O3) can induce clinical remission in patients with acute promyelocytic leukemia via induction of differentiation and programmed cell death (apoptosis). We investigated the effects of As2O3 on a panel of malignant lymphocytes to determine whether growth-inhibitory and apoptotic effects of As2O3 can be observed in these cells at clinically achievable concentrations...
PURPOSE To determine the optimal combination of parameters derived from 3T multiparametric (conventional magnetic resonance imaging [MRI], diffusion-weighted [DW] and dynamic contrast-enhanced [DCE]) MRI for differentiating malignant from benign orbital lymphoproliferative disorders (OLPDs). MATERIALS AND METHODS Forty patients with OLPDs (18 benign and 22 malignant) underwent conventional 3....
BACKGROUND AND PURPOSE Accurate discrimination of orbital lymphoma from benign orbital lymphoproliferative disorders is crucial for treatment planning. We evaluated MR imaging including DWI and contrast-enhanced MR imaging for differentiating orbital lymphoma from benign orbital lymphoproliferative disorders. MATERIALS AND METHODS Forty-seven histopathologically proved orbital lymphoprolifera...
