Radiation therapy is sometimes performed to control intracranial acute lymphoblastic leukemia (ALL), but may lead to radiation-induced malignant glioma. The clinical, radiological, histological, and molecular findings are described of three cases of radiation-induced glioblastoma after the treatment for ALL. They received radiation therapy at age 6-8 years. The latency from radiation therapy to the onset of radiation-induced glioblastoma was 5-10 years. Magnetic resonance imaging demonstrated diffuse lesions with multiple small enhanced lesions in all cases...

BACKGROUND Type-B lactic acidosis is a rare complication of solid tumors and hematological malignancies. It occurs secondary to Warburg effect, when glucose metabolism in cancer cells switches from the oxidative pathway to the glycolytic pathway. Malignant lactic acidosis is a life-threatening condition if not promptly diagnosed and treated urgently. CASE REPORT We report the case of a 58-year-old male patient who presented with severe chest pain, dyspnea, systemic symptoms, leukopenia, normocytic anemia, and severe lactic acidosis...

A 62-year-old man presented to the hospital with thrombocytopenia, and splenomegaly was detected. His blood films prepared by natural air drying revealed medium-sized lymphocytes with unevenly distributed large and small villous projections. The cytoplasm was basophilic, nuclei were oval with clumped chromatin, and nucleoli were absent in most cells. Immune phenotypes CD19+, CD20+, CD11c+, FMC7+, IgM+, and Igκ+ were detected. TRAP stain appeared negative, IgH JH chain genes were monoclonally rearranged, and BRAF V600E mutation was not detected...

We present a case of a 48-year-old male who presented with worsening pleuritic chest pain for 2 h. He also complained of fever, malaise, headache and severe neck pain. Electrocardiogram (ECG) showed ST segment elevation in leads I, II, aVL and V5 with PR elevation and ST depression in aVR. On admission, troponin-I was 14.8 ng/mL. Based on ECG changes, elevated troponin and family history of early coronary artery disease, the patient was emergently taken to cardiac catheterization lab. Angiography showed non-obstructive coronaries, mild hypokinesis of mid inferior and anterolateral wall with ejection fraction (EF) of 40-45%...

Orbital involvement in chronic lymphocytic leukemia (CLL) is rare with very few published cases. We describe a case of unilateral isolated extraocular muscle enlargement in a patient with CLL. An incisional biopsy was performed from the left medial rectus muscle and histology revealed a lymphocytic infiltrate suggestive of CLL. Complete resolution of signs and symptoms was subsequently achieved with chemotherapy. We would suggest that in patients presenting with atypical clinical features, it is important to consider nonthyroid-related causes of extraocular muscle enlargement and a muscle biopsy should be considered to exclude neoplastic causes...

Infectious diseases can be caused by multiple pathogens, which can produce specific immune response in human body. The immune response produced by T cells is cellular immunity, which plays an important role in the anti-infection process of human body, and can participate in immunological protection and cause immunopathology. The outcome of various infectious diseases is closely related to cellular immune function, especially the function of T cells. Jurkat cells belong to the human acute T lymphocyte leukemia cell line...

Pierre Laneuville
Strict criteria for when to stop tyrosine kinase inhibitor (TKI) therapy in clinical practice are not easily defined without an agreement on what probability of achieving a treatment-free remission (TFR) constitutes a medically acceptable standard and consideration of the potential medical risks of continued TKI therapy and/or patient preferences. Patients in sustained deep molecular response (DMR) have no significant chronic myelogenous leukemia-related risk of progression and death, and thus, safety is of paramount importance...

We report on three cases of pediatric acute lymphoblastic leukemia presenting with bone pain and arthralgia as initial symptoms. At the first visit, their primary signs were recurrent bone pain and arthralgia, without significant peripheral blood abnormalities. It took 2-4 months to confirm the diagnosis from the onset of arthralgia due to this atypical presentation of the disease. Definitive diagnosis was obtained by bone marrow examination, and in all cases, complete remission was achieved by chemotherapy...

Atypical chronic myeloid leukaemia (aCML) belongs to myelodysplastic/myeloproliferative neoplasms. Because of its rarity and changing diagnostic criteria throughout subsequent classifications, data on aCML are very scarce. Therefore, we at the Polish Adult Leukemia Group performed a nationwide survey on aCML. Eleven biggest Polish centres participated in the study. Altogether, 45 patients were reported, among whom only 18 patients (40%) fulfilled diagnostic criteria. Among misdiagnosed patients, myelodysplastic/myeloproliferative syndrome unclassifiable and chronic myelomonocytic leukaemia were the most frequent diagnoses...

The World Health Organization classifies atypical chronic myeloid leukemia (aCML) as a myeloproliferative/myelodisplastic hematological disorder. The primary manifestations are leukocytosis with disgranulopoiesis, absence of basophilia and/or monocytosis, splenomegaly and absence of Philadelphia chromosome or BCR/ABL fusion. Overall 50-65% of patients demonstrate karyotypic abnormalities, although no specific cytogenetic alterations have been associated with this disease. X chromosome alterations have been rarely reported in myeloid malignancies...

BACKGROUND: Mast cell leukemia (MCL) is a very rare form of systemic mastocytosis (SM) and accounts for less than 0.5% of all mastocytosis. The diagnosis of MCL requires the presence of SM criteria, accompanied by leukemic infiltrating of atypical mast cells (MCs) in bone marrow (BM), peripheral blood as well as extracutaneous organs. MCL is a fatal disease that almost always behaves aggressively, and the median survival time is only about six months. Herein, we present a rare case of de novo MCL without CD25 expression and KIT mutations...

Atypical Chronic Myeloid Leukemia (aCML) is a myeloproliferative neoplasm characterized by neutrophilic leukocytosis and dysgranulopoiesis. From a genetic point of view, aCML shows a heterogeneous mutational landscape with mutations affecting signal transduction proteins but also broad genetic modifiers and chromatin remodelers, making difficult to understand the molecular mechanisms causing the onset of the disease. The JAK-STAT, MAPK and ROCK pathways are known to be responsible for myeloproliferation in physiological conditions and to be aberrantly activated in myeloproliferative diseases...

Oral fungal infections present with atypical and varied manifestations, and distinguishing them from other entities including leukemic infiltration can be diagnostically challenging. In this report, we describe a 62 year old female with acute myeloid leukemia who presented, towards the end of her second treatment cycle of decitabine in a prolonged neutropenic state, with a month of painful, necrotic-appearing marginal gingival lesions. She was duly initiated on empiric broad spectrum antifungal treatment but did not show a clinical response with the appearance of new skin lesions concerning for progressive fungemia...

RATIONALE: Patients with the e6a2 BCR-ABL transcript, 1 of the atypical transcripts, have been reported to have a poor prognosis, and allogeneic stem cell transplantation (ASCT) can be considered as additional therapy. However, long-term survival after ASCT for this disease is rare. PATIENT CONCERNS: This report concerns a 55-year-old female patient with e6a2 BCR-ABL-positive acute myeloid leukemia including the outcome of ASCT followed by donor lymphocyte infusion (DLI)...

Mucormycosis of the scalp is a rare cutaneous presentation of the disease. It is also an unusual infection in children. We present the case of a 4-year-old girl with acute lymphoblastic leukemia, who presented with atypical cutaneous mucormycosis simulating an ecthyma gangrenosum lesion. Risk factors for the infection are diabetes, neoplastic diseases, immunosuppression in organ transplant recipients, and neutropenia. The cutaneos forms have been associated with trauma, burns and surgical wounds. First line treatment is amphotericin B...

Background: A leukemic hypopyon is considered an early sign of central nervous system involvement or systemic relapse. A differential diagnosis of masquerade syndromes should be considered in cases of hypopyon uveitis that are atypical or unresponsive to treatment. We report a case of a 45-year-old man who presented with bilateral hypopyon uveitis and was subsequently diagnosed as having chronic myeloid leukemia. Method: Retrospective case review. Results: A 45-year-old diabetic male presented with diminished vision in both eyes for 10 days...

Atypical breakpoints and variant APL cases involving alternative chromosomal aberrations are seen in a small subset of acute promyelocytic leukemia (APL) patients. Over seven different partner genes for RARA have been described. Although rare, these variants prove to be a diagnostic challenge and require a combination of advanced cytogenetic and molecular techniques for accurate characterization. Heterogeneity occurs not only at the molecular level but also at clinico-pathological level influencing treatment response and outcome...

Hepatic Veno-Occlusive Disease (VOD) is a potentially severe complication of hematopoietic stem cell transplantation (HSCT). Here we report two patients receiving an allogeneic HSCT who developed late onset VOD with atypical clinical features. The two patients presented with only few risk factors, namely, advanced acute leukemia, a myeloablative busulphan-containing regimen and received grafts from an unrelated donor. The first patient did not experience painful hepatomegaly and weight gain and both patients showed only a mild elevation in total serum bilirubin level...
