Cell surface immunoglobulin, complement receptor, and spontaneous rosette formation with sheep erythrocytes were investigated in 43 patients with malignant lymphoma, including 13 with lymphosarcoma cell leukemia, and in 59 patients with chronic lymphocytic leukemia. The quantity of immunoglobulin on the lymphocyte surface was estimated from the intensity of fluorescent staining with fluorescein...

To assess the effect of ABO-identical, filtration leukodepleted transfusions on resource consumption and costs of care we performed a cohort study in consecutive adult patients admitted for induction therapy of acute myeloid or lymphoid leukemia during 1985-92 (n = 120) and consecutive adult patients admitted for autologous bone marrow transplantation for Hodgkin's or non-Hodgkin's lymphoma dur...

Methotrexate is an anti-rheumatic agent used as a first-line tretment for rheumatoid arthritis. Hematological malignancies like lymphoma or acute myeloid leukemia have been reported to be secondary to treatment with Methotrexate, but are very uncommon. We report here the first Moroccan case of RA patient on low dose MTX, who developed AML. We also reviewed all similar cases.

The activities of thymidine kinase (TK) isoenzyme 1 and 2 were examined in extracts of human benign or malignant lymphoid tissue and correlated with degrees of morphological differentiation. TK2 activity occurred in peripheral blood lymphocytes of normal individuals, patients with chronic lymphocytic leukemia, or solid lymphoid tissue, exhibiting either nonneoplastic histological findings or th...

Studies were undertaken to determine whether leukemia and lymphoma cells would be lysed by autologous and allogeneic interferon (IFN) activated peripheral blood mononuclear cells (PBMC). PBMC from healthy donors and from patients were cultured with and without 500 U of highly purified human fibroblast IFN/ml for 24 hr, and then their cytotoxic activity was assayed by a 5-hr 51Cr-release test. O...

The activities of thymidine kinase (TK) isoenzyme 1 and 2 were examined in extracts of human benign or malignant lymphoid tissue and correlated with degrees of morphological differentiation. TK2 activity occurred in peripheral blood lym phocytes of normal individuals, patients with chronic lymphocytic leukemia, or solid lymphoid tissue, exhibiting either nonneoplastic histological findings or t...

Background: Chronic lymphocytic leukemia (CLL) can transform into fast growing lymphoma for diffuse large B-cell lymphoma (DLBCL) called Richter's syndrome (RS), which is commonly related to an existence of large B-cells with equal or larger size than macrophage nuclei or more than twice those of normal lymphocyte. We conducted a systematic review of the existing literature to assess the clinic...

Introduction: The diagnosis of chronic lymphocytic leukemia/ small lymphoma (CLL/SLL), which also includes atypical forms, can be very difficult. aim this study is to compare immunohistochemical (IHC) and flow cytometric (FC) immunophenotyping methods in the CLL/SLL, most common mature B-cell leukemia/lymphoma adults, bone marrow biopsy. In these two methods, it determine minimum panels that di...

myeloid sarcoma of female breast is a rare presentation of acute myeloid leukemia (aml). the tumor mass may precede or occur concurrently with aml, cml, myeloproliferative disorders, and/or myelodysplastic syndromes. histologically, it looks like a large cell lymphoma and can be misdiagnosed. a case referred as a suspected case of large cell lymphoma. initial morphological study with convention...
