background: mature t/ nk-cell neoplasms are a rare group of disorders and their presentation as leukemia is even rarer. most of the previous studies have focused on mature b-cell lineage leukemias and there is a paucity of data on mature t/nk-cell lineage leukemias. we, therefore, planned this study to analyze their spectrum, frequency, morphology and immunophenotypic features. methods: all cas...

background: burkitt lymphoma is a common subtype of non-hodgkin lymphoma in children. it has a rapid and aggressive clinical course with frequent involvement of bone marrow and central nervous system. systemic chemotherapy is the mainstay of the treatment for this malignancy in children. in this systematic review, we discuss autologous and allogeneic hematopoietic stem cell transplantation (hsc...

Monoclonal B-Cell Lymphocytosis (MBL) is part of the mature B-cell neoplasms despite actually being a pre-neoplastic condition [1], this entity, largely unstudied, affects more than 5-10% older adults age 40 and incidence increases with aging [2,3], MBL widely associated as one main risk factors for developing Chronic Lymphocytic Leukemia (CLL)/Small Cell Lymphoma (SLL), since studies Prospecti...

BACKGROUND Distinction between mature B-cell neoplasms can be difficult due to overlapping of immunologic features and clinical manifestations. This study investigated whether quantifying mean fluorescence intensity of four monoclonal antibodies in a flow cytometry panel is useful for the differential diagnosis and characterization of these disorders. METHODS The expressions of CD52, CD200, C...

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...

Literature review shows that hepatitis C infection may increase the risk of non-hodgkin lymphoma. Reactivation of hepatitis B infection has been reported in patients with hairy cell leukemia after chemotherapy and/or splenectomy. We present hepatitis B surface (HBs) antigenemia and concurrent hepatitis C virus (HCV) seropositivity in a case of hairy cell leukemia. Key Words: Hairy cell leukemi...

The TCL1 gene at 14q32.1 is involved in chromosomal translocations and inversions in mature T cell leukemias. These leukemias are classified either as T prolymphocytic leukemias, which occur very late in life, or as T chronic lymphocytic leukemias, which often arise in patients with ataxia telangiectasia (AT) at a young age. In transgenic animals, the deregulated expression of TCL1 leads to mat...
