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, since 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...

STUDY QUESTION: What is the risk of finding malignant cells in cryopreserved ovarian tissue from sarcoma patients? SUMMARY ANSWER: Minimal disseminated disease (MDD) was not detected in frozen-thawed ovarian tissue from 26 patients by any of the sensitive methods applied. WHAT IS KNOWN ALREADY: In case of leukemia, the risk of malignant cell transmission through the graft is well known and widely documented. However, for bone cancer, like Ewing sarcoma or osteosarcoma, only a small number of case reports, have been published...

Similar to the inherent clinical heterogeneity of most, if not all, lymphoma entities, the genetic landscape of these tumors is markedly complex in the majority of cases, with a rapidly growing list of recurrently mutated genes discovered in recent years by next-generation sequencing technology. Whilst a few genes have been implied to have diagnostic, prognostic and even predictive impact, most gene mutations still require rigorous validation in larger, preferably prospective patient series, to scrutinize their potential role in lymphoma diagnostics and patient management...

Worldwide, marijuana (cannabis) is a widely used drug. The incidence of marijuana smoking is increasing and is second only to tobacco as the most widely smoked substance in the general population. It is also the second most commonly used recreational drug after alcohol. Some adverse effects of marijuana smoking have been documented; however, the number of studies on the pulmonary effects of marijuana in individuals with leukemia is limited. In our case series, we report on 2 men with acute myeloid leukemia with miliary nodular lung patterns on computed tomography of the chest due to heavy marijuana use...

Diffuse alveolar hemorrhage is a potentially fatal pulmonary disease syndrome that affects individuals with hematological and nonhematological malignancies. The range of inciting factors is wide for this syndrome and includes thrombocytopenia, underlying infection, coagulopathy, and the frequent use of anticoagulants, given the high incidence of venous thrombosis in this population. Dyspnea, fever, and cough are commonly presenting symptoms. However, clinical manifestations can be variable. Obvious bleeding (hemoptysis) is not always present and can pose a potential diagnostic challenge...

The Guillain-Barré syndrome (GBS) is one of the few neuropathies well known to the general public, in part because of its association with swine flu vaccinations in 1976. GBS has again reached the general public with its possible association with Zika virus. The virus, borne by infected Aedes aegypti mosquitos, is being linked to birth defects when pregnant women are bitten and infected. There are early reports also linking GBS to Zika infection, which could expose a wider range of infected people to the neuropathy...

Plasma cell leukemia (PCL) is an uncommon neoplasm of plasma cells, with an aggressive clinical course and poor outcome, even with current standard of care. It can occur either de novo (primary PCL) or as a progression of multiple myeloma (MM). This disease has unique diagnostic criteria but certain genetic markers and clinical features may overlap with MM. Due to the low prevalence of PCL, guidelines on its management are extrapolated from the management of MM and based on small retrospective studies and cases reports/series...

BACKGROUND: Identification of aberrant antigen expression is important in characterizing neoplastic population among non.neoplastic bone marrow counterparts and further in the detection of minimal residual disease. (MRD). Flow cytometry (FCM) is an important tool in identifying aberrant phenotypes. Incidence of aberrant phenotypes varies considerably in independent studies and its association with prognostic factors is still debatable. AIM: To identify the prevalence of aberrant phenotypes on immunophenotyping in a large series of de novo acute lymphoblastic leukemia (ALL) and to evaluate any association with initial clinical and hematological features...

In a series of 107 patients suffering from acute myeloid leukemia (AML), blast cells from six patients were found to simultaneously express CD2 and CD7 antigens along with CD13, CD33, and CDw 65 in various combinations. The frequency of the expression of both lymphoid markers recurred with a higher incidence than that anticipated by multiplying single antigens frequency. The clinical and hematologic features from CD2+/CD7 + AML patients were studied as well as compared with those of CD2-/CD7- AML patients observed in the same period...
