Immunophenotyping studies with monoclonal antibodies have revealed the heterogeneity of childhood acute lymphoblastic leukemia (ALL) and non-Hodgkin's lymphoma (NHL). The lymphoid malignancies of T-cell lineage are particularly heterogeneous and, until now, no single monoclonal antibody has been found to identify all cases of T-ALL and T-NHL. A monoclonal antibody, 4H9, recognizes an antigen of...
Pure erythroid leukemia (PEL) is rare hematopoietic neoplasm characterized by uncontrolled proliferation of immature erythroid precursors - mainly abnormal proery-throblasts - comprising at least 80% of bone marrow cells. In this paper, I present a case of 48 years old patient, who presented with pancytopenia and circulating erythroblast in peripheral blood after long history of alcohol abuse. ...
The immunophenotype of lymphoid cytologic samples obtained by laser scanning cytometry (LSC) and flow cytometry (FC) was compared in 72 cases composed of a series of 23 cases with simultaneous LSC and FC immunophenotyping and a second series of 49 cases in which nonsimultaneous immunophenotyping was performed. In both series, no discordance in the population immunophenotype was found that would...
Quantification of bone marrow plasma cells in multiple myeloma patients using conventional morphology is of limited prognostic value, while the merit of multiparameter flow cytometry immunophenotyping is still considered unproven. Here we compare the bone marrow plasma cell counts obtained by morphology and multiparameter flow cytometry and explore the potential prognostic impact of both techni...
Monoclonal antibody SM 92 is involved in the immunophenotype of gastrointestinal and liver cells, SM 43 in ovarian cells, and SM 13 in lung cells. Based on a study of 61 breast adenocarcinoma patients, we found that tumors reacting with SM 92 appear associated with liver metastases, SM 43 with ovarian metastases, and SM 13 with lung metastases. These associations are highly significant. They le...
INTRODUCTION Non-Hodgkin's lymphomas (NHLs) are heterogeneous group of malignant lymphoproliferative disorders. STUDY OBJECTIVES This was a retrospective study aimed to classify NHLs into B cell and T cell types; in addition to demonstrate the histological patterns and correlate it with gender, age and site of the biopsy. METHODS The study was conducted in Histopathology Department, Nationa...
Flow cytometric immunophenotyping remains an indispensable tool for the diagnosis, classification, staging, and monitoring of hematologic neoplasms. The last 10 years have seen advances in flow cytometry instrumentation and availability of an expanded range of antibodies and fluorochromes that have improved our ability to identify different normal cell populations and recognize phenotypic aberr...
Immunophenotyping of acute leukaemias has become an important diagnostic tool in haematology laboratories as it is now well recognised that the presence of certain surface markers has prognostic significance. In 1988, we experimented with the alkaline phosphatase anti-alkaline phosphatase (APAAP) method for immunophenotyping of leukaemic cells in our laboratory. 48 cases of peroxidase-negative ...
