A balanced translocation t(8;9) (p11;q34) was present in the peripheral blood, bone marrow, and spleen cells of a patient with Ph negative chronic myeloid leukaemia. Subsequent transformation into acute leukaemia was associated with the emergence of trisomy 8 and der(8)(8qter----cen----8p11::9q34----9qter). This is the third reported case of t(8;9) (p11;q34) and raises the question of the role ...

Orbital or subconjunctival infiltration occurs frequently in acute and chronic lymphatic leukaemia, but only rarely in myelogenous leukaemia (Chatterjee and Sen, I 960). Chloroma, an atypical form of myeloblastic leukaemia, often manifests itself as a localized mass in the orbital periosteum, and the proptosis produced in such cases may be the first sign of the disease (Goodman and Iverson, I94...

Leukaemia cells that are resistant to conventional therapies are thought to reside in protective niches. Here, we describe light-inducible polymeric retinoic acid (RA)-containing nanoparticles (NPs) with the capacity to accumulate in the cytoplasm of leukaemia cells for several days and release their RA payloads within a few minutes upon exposure to blue/UV light. Compared to NPs that are not a...

Myeloid sarcoma is rare and nasal chloroma an uncommon initial manifestation of acute myeloid leukaemia. The correct diagnosis a big challenge. In this report, we present case the cavity with extension to soft tissues face. A 53-year-old woman past medical history thalassemia, not followed up, presented progressive greyish swelling in her right cheek associated obstruction more marked on side u...

Circulating antibody to endotoxin core glycolipid and total serum immunoglobulin concentrations were measured in 86 children with cancer (54 with acute lymphoblastic leukaemia, four with acute myeloid leukaemia, and 28 with various solid tumours). Measurements were made before treatment in the group with acute lymphoblastic leukaemia as well as when patients were both on and off chemotherapy. I...

Introduction: Bone marrow aspiration (BMA) is an important tool in diagnosis of many haematological and non-haematological diseases. BMA usually done together with complete blood cell count (CBC) peripheral picture. needed for hypersplinsm. alone sufficient megaloblastic anaemia, microcytic acute leukaemia, chronic myeloid lymphocytic leukaemia immune thrombocytopenic purpura (ITP). The objecti...

BACKGROUND The Surveillance of Rare Cancers in Europe (RARECARE) project aims at increasing knowledge of rare cancers in Europe. This manuscript describes the epidemiology of myeloid malignancies (MMs), taking into account the morphological characterisation of these tumours. METHODS We used data gathered by RARECARE on cancer patients diagnosed from 1995 to 2002 and archived in 64 European po...

A three-month-old female Holstein-Friesian calf was presented with acute tetraparesis. After neurological examination a multifocal lesion in the central nervous system was suspected with the most pronounced lesions between the third thoracic and the third lumbar vertebrae. Haematological examination revealed moderate anaemia as well as severe thrombocytopenia, neutropenia and leucocytosis. A bl...

The BCR/ABL1 fusion gene, usually carried by the Philadelphia chromosome (Ph) resulting from t(9;22)(q34;q11) or variants, is pathognomonic for chronic myeloid leukaemia (CML). It is also occasionally found in acute lymphoblastic leukaemia (ALL) mostly in adults and rarely in de novo acute myeloid leukaemia (AML). Array Comparative Genomic Hybridization (aCGH) was used to study six Ph(+)AML, th...

Introduction The standard approach to the diagnosis of acute leukaemia and myelodysplasia has been based on the morphology and percentage of malignant haemopoietic cells in peripheral blood and in an aspirated sample of bone marrow. The FAB group reports on acute leukaemia have emphasised the value of additional information gained from cytochemistry,' and immunological studies and cytogenetics ...
