hypercalcemia in children is a medical emergency and often manifests as nonspecific symptoms such as nausea, vomiting, weight loss, and anorexia. severe hypercalcemia is a rare complication of malignancy in children, while it can be seen in various types of malignant tumors. it is usually associated with significant morbidity and may be severe enough to threaten life. incidence of hypercalcemia...

Abnormalities of the thyroid gland are among the most frequent endocrine complications observed in childhood cancer survivors. We report an 11 years old girl who developed central hypothyroidism and ACTH deficiency during the chemotherapy for CNS relapse of acute lymphoblastic leukemia before receiving radiotherapy. Keywords: Thyroid gland, hypothyroidism, chemotherapy, acute lymphoblastic leu...

BACKGROUND MicroRNA regulate the activity of protein-coding genes including those involved in hematopoietic cancers. The aim of the current study was to explore which microRNA are unique for seven different subtypes of pediatric acute lymphoblastic leukemia. DESIGN AND METHODS Expression levels of 397 microRNA (including novel microRNA) were measured by quantitative real-time polymerase chain...

Three distinct immature T-cell acute lymphoblastic leukemia entities have been described including cases that express an early T-cell precursor immunophenotype or expression profile, immature MEF2C-dysregulated T-cell acute lymphoblastic leukemia cluster cases based on gene expression analysis (immature cluster) and cases that retain non-rearranged TRG@ loci. Early T-cell precursor acute lympho...

Indolent T-lymphoblastic proliferation (iT-LBP) is a recently recognized benign pathologic condition commonly associated with Castleman disease. The lymph node of this shows preserved lymphoid architecture nonclonal T-lymphoblasts in the interfollicular area. iT-LBP rare and diagnosis exclusion. As rule, it requires sophisticated techniques to exclude leukemia/lymphoma (T-LBL/L). We present an ...

Infiltration of the central nervous system is a severe trait of T cell acute lymphoblastic leukemia. Inhibition of CXC chemokine receptor 4 significantly ameliorates T cell acute lymphoblastic leukemia in murine models of the disease; however, signaling by CXC chemokine receptor 4 is important in limiting the divagation of peripheral blood mononuclear cells out of the perivascular space into th...

Background: Acute lymphoblastic leukemia is a rare hematological malignancy. Pure subdural hemorrhages in a patient with acute lymphoblastic leukemia patient are extremely rare. Case presentation: This case presented acute spontaneous subdural hemorrhage without head trauma at first, and acute lymphoblastic leukemia was diagnosed later. The second time, the patient was admitted with multiple pu...

Advances in the molecular characterization of leukemic cells have greatly improved the precision of diagnosis and treatment assignment as well as the monitoring of residual disease in both acute lymphoblastic leukemia and acute myeloid leukemia. Currently, specific genetic rearrangements can be identified in as many as 50% of children with either acute lymphoblastic leukemia or acute myeloid le...

Although childhood acute lymphoblastic leukemia is the most common pediatric cancer, its etiology remains poorly understood. In an attempt to replicate the findings of 2 recent genome-wide association studies in a French-Canadian cohort, we confirmed the association of 5 SNPs [rs7073837 (P=4.2 x 10(-4)), rs10994982 (P=3.8 x 10(-4)), rs10740055 (P=1.6 x 10(-5)), rs10821936 (P=1.7 x 10(-7)) and r...

We report a case of bone marrow necrosis preceding infantile acute lymphoblastic leukaemia (ALL). Bone marrow necrosis is a rare antemortem event and has been known to be present in many conditions, notably in haematological malignancies like acute lymphoblastic leukaemia. This case was a 6-month-old Chinese boy who was referred to Hospital Universiti Kebangsaan Malaysia for further investigati...
