Basophils form a distinct cell lineage within the hematopoietic cell family. In various myeloid neoplasms, including chronic myeloid leukemia (CML), basophilia is frequently seen. Acute and chronic basophilic leukemias, albeit rare, have also been described. However, no generally accepted criteria and classification of basophilic leukemias have been presented to date. In order to address this unmet need, a series of Working Conferences and other meetings were organized between March 2015 and March 2016. The current article provides a summary of consensus statements from these meetings, together with proposed criteria to delineate acute basophilic leukemia (ABL) from chronic basophilic leukemia (CBL) and primary forms of the disease where no preceding myeloid malignancy is detected, from the more common ´secondary´ variants...

Small lymphocytic lymphoma/chronic lymphocytic leukemia (CLL/SLL) and mantle cell lymphoma (MCL) usually are distinctly different in regard to clinical presentation, morphology, immunophenotype and molecular/genetic findings. In spite of this, select cases may show overlapping characteristics and represent a diagnostic challenge. Recently LEF1 staining was identified as a fairly characteristic finding in CLL/SLL, with positivity identified in up to 95% of cases. LEF1 staining has not been reported as being present in cases of MCL, making this stain a useful tool in distinguishing these diagnoses...

INTRODUCTION: The Philadelphia chromosome (Ph) is the most common cytogenetic abnormality associated with adult acute lymphoblastic leukemia (ALL) occurring in 20% to 40% of patients. It is also detected in 2% to 5% of children with ALL. Historically, patients with Ph-positive ALL carried a dismal prognosis, with poor response to most chemotherapy combinations, short remission durations, and long-term disease-free survival rates of 10% to 20%. The advent of tyrosine kinase inhibitors (TKIs) has revolutionized therapy of Ph-positive ALL...

OBJECTIVE: Demographic and clinical characteristics associated with nonarteritic anterior ischemic optic neuropathy (NAION) are well described. Patients with hematologic neoplasms may share some of these characteristics, and it may be useful clinically to better understand this set of patients. Our objective is to review systematically the characteristics of patients with both hematologic malignancies and NAION. DESIGN: Systematic review. PARTICIPANTS: Patients with NAION diagnosis related in time to a hematologic neoplasm...

The paper continues the series of publications from the International Nuclear Workers Study cohort (INWORKS) that comprises 308,297 workers from France, the United Kingdom and the United States, providing 8.2 million person-years of observation from a combined follow-up period (at earliest 1944 to at latest 2005). These workers' external radiation exposures were primarily to photons, resulting in an estimated average career absorbed dose to the colon of 17.4 milligray. The association between cumulative ionizing radiation dose and cancer mortality was evaluated in general relative risk models that describe modification of the excess relative risk (ERR) per gray (Gy) by time since exposure and age at exposure...

AIMS: Richter transformation (RT) occurs in 5-10% of patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) and is associated with a poor outcome. Histologic manifestations of RT are variable and include an increase in the proportion of large cells including prolymphocytes, immunoblasts and other pleomorphic cells along with an increased proliferation rate and often necrosis. Rarely, superimposed Herpes simplex virus (HSV) infection involving lymph nodes in patients with CLL/SLL may mimic RT clinically and histologically...

Acute Leukemia is one of the common haematological malignancies encountered with varied clinical and haematological presentation. In acute leukaemia, complications like bleeding and infection cause significant morbidity and mortality, thus overshadowing the thromboembolic events. Among the various malignant haematological disorders, the association of thromboembolic events is often noted with acute promyelocytic leukemia, though the overall frequency of such events remains very low. Acute Lymphoblastic Leukemia (ALL) is, however, more common than Acute non-lymphoblastic Leukaemia...

BACKGROUND: Acute myeloid leukemia presenting the MYST3-CREBBP fusion gene is a rare subgroup associated with hemophagocytosis in early infancy and monocytic differentiation. The aim of this study was to define the relevant molecular cytogenetic characteristics of a unique series of early infancy acute myeloid leukemia cases (≤24months old), based on the presence of hemophagocytosis by blast cells at diagnosis. METHODS: A series of 266 infant cases of acute myeloid leukemia was the reference cohort for the present analysis...

Patients with chronic lymphocytic leukemia (CLL) harboring TP53 aberrations (TP53abs; chromosome 17p deletion and/or TP53 mutation) exhibit an unfavorable clinical outcome. Chromosome 8 abnormalities, namely losses of 8p (8p-) and gains of 8q (8q+) have been suggested to aggravate the outcome of patients with TP53abs. However, the reported series were small, thus hindering definitive conclusions. To gain insight into this issue, we assessed a series of 101 CLL patients harboring TP53 disruption. The frequency of 8p- and 8q+ was 14...

BACKGROUND: Molecularly targeted therapy has revolutionized the treatment of advanced gastrointestinal stromal tumors (GISTs). Specifically, the consistent dependence of GISTs on proto-oncogene c-KIT signaling led to the development and successful implementation of imatinib, a small-molecule c-KIT inhibitor. Imatinib induces, rapid and sustained clinical benefit by blocking the signaling via c-KIT. The most frequently reported adverse reactions (>30%) include edema, nausea, vomiting, muscle cramps, musculoskeletal pain, diarrhea, rash, fatigue and abdominal pain...

Juvenile myelomonocytic leukemia (JMML), previously known as juvenile chronic myeloid leukemia (JCML), is a rare, myelodysplastic-myeloproliferative disease typically presenting in early childhood. This disorder is difficult to distinguish from other myeloproliferative syndromes such as chronic myeloid leukemia (CML) because of the similarities in their clinical and bone marrow findings. However, because of its unique biological characteristics such as absolute monocytosis with dysplasia, absence of Philadelphia chromosome or BCR-ABL fusion protein, hypergammaglobulinemia, and raised fetal hemoglobin level, this disorder does not satisfy the criteria for inclusion in the CML or chronic myelomonocytic leukemia (CMML) group, as seen in adult patients...

Hepatosplenic T-cell lymphoma (HSTCL) is a rare, aggressive T-cell lymphoma that can be challenging to diagnose. In particular, distinguishing HSTCL from T-cell large granular lymphocytic (T-LGL) leukemia of γδ T-cell receptor (TCR) type is difficult without examination of a splenectomy specimen. In this study, we systematically assessed a series of HSTCL cases for findings reported in the literature as supporting or not supporting the diagnosis of HSTCL. We also compared HSTCL with a group of cases of T-LGL of γδ TCR type...

The extremely low efficient cytosolic release of the internalized siRNA has emerged recently as a central issue for siRNA delivery, while there is a lack of guidelines to facilitate the cytosolic release of internalized siRNA. To address these concerns, we studied the contribution of the pH-sensitive inner core on handling the cytosolic release of siRNA delivered by a series of PG-P(DPAx-co-DMAEMAy)-PCB amphiphilic polycation nanomicelles (GDDC-Ms) with extremely low internalization (<1/4 of lipofactamine 2000 (Lipo2000))...

INTRODUCTION: Chronic myeloid leukemia (CML) is a myeloproliferative disorder characterized by Philadelphia (Ph) chromosome with classical t(9;22)(q34;q11) seen in up to 90% of cases. However 5% to 10% of patients who present with variant Ph translocations (vPh) have been an area of research for their significance in predicting response to various therapies including tyrosine kinase inhibitors as well as prognosticating survival outcomes for many years involving varied patient populations, with conflicting results...

Cytogenetics has a pivotal role in risk stratification of acute myeloid leukemia (AML). We report a case of AML with a t(4;12)(q12;p13). To the best of our knowledge, there are about 24 cases of t(4;12) reported in AML which are usually misdiagnosed as lymphoproliferative disorders on morphological assessment. This case showed specific clinical, morphological, and immunophenotypic features such as (1) pseudo lymphoid morphology, (2) dysplasia in granulocytic series, (3) an immature immunophenotype with positivity for CD34 and CD117, and (4) poor treatment response...

Imatinib, an orally administered protein-tyrosine kinase inhibitor (TKI) is indicated for the treatment of chronic myeloid leukemia (CML) and gastrointestinal stromal tumor (GIST). Severe hepatotoxicity associated with imatinib is rare, and relationship to polymorphism of uridine diphosphate glucuronosyltransferase 1A1 (UGT1A1) expression and related frequency of hyperbilirubinemia or toxicity are not well known. We present a case series patients who developed hyperbilirubinemia while on oral administration imatinib for treatment of GIST...

Pediatric acute myeloid leukemia (AML) is a rare disease whose prognosis is highly variable according to factors such as chromosomal abnormalities. Recurrent genomic rearrangements are detected in half of pediatric AML by karyotype. NUcleoPorin 98 (NUP98) gene is rearranged with 31 different fusion partner genes. These rearrangements are frequently undetected by conventional cytogenetics, as the NUP98 gene is located at the end of the chromosome 11 short arm (11p15). By screening a series of 574 pediatric AML, we detected a NUP98 rearrangement in 22 cases (3...

BACKGROUND: The most common type of ocular lymphoma is non-Hodgkin lymphoma (NHL), categorized into two groups: indolent (slow growing) and aggressive (rapid growing). Differentiating benign reactive lymphoid hyperplasia (RLH) from malignant ocular adnexal lymphoma (OAL) is challenging. Histopathology, immunohistochemistry (IHC) and ow cytometry have been used as diagnostic tools in such cases. MATERIALS AND METHODS: In this retrospective case series, from 2002 to 2013 at Farabi Eye Center, 110 patients with ocular lymphoproliferative disease were enrolled...

Treatment of pediatric acute lymphoblastic leukemia (ALL) relies on systemic corticosteroids for remission; however, they can cause significant mood and behavior changes that interfere with quality of life and may increase risk for injury. This case series reports on preschool children with preexisting developmental and psychiatric risk factors who presented with behavioral side effects that required intervention. Identification of these vulnerable children may provide opportunities for early intervention, anticipatory guidance, and effective treatment to minimize behavioral side effects and improve quality of life and safety during ALL treatment...
