Granulocytic sarcoma is a rare extramedullary tumour, which most often occurs in the course of an acute or chronic leukaemia or myeloproliferative disorders. Rarely it is found before peripheral blood or bone marrow evidence of leukemia is present. We report an unusual case of acute paraplegia at first presentation of a spinal epidural granulocytic sarcoma without any haematological disorder. T...

Essential thrombocythemia (ET) is a chronic myeloproliferative disorder characterized by thrombo-hemorrhagic complications. But aortic thrombus formation is not so common in the patients with ET at the initial diagnosis. We describe a 65-year-old woman with ET found to have a thoraco-abdominal aortic thrombosis and have splenic infarction, which were successfully treated with medical therapy al...

Erythromelalgia is a rare disorder frequently associated with myeloproliferative disorders. We describe a case of elderly patient diagnosed with myeloproliferative disorder in remission. The patient was on aspirin for secondary prevention of stroke and was taken off aspirin and developed erythromelalgia within two weeks of withdrawal of aspirin. After restarting aspirin, patient's symptoms impr...

Polycythemia rubra vera (PV) is a chronic myeloproliferative disorder characterized by elevated red cell mass with an increased risk of both thrombosis and bleeding. Thromboembolic events are the most significant and life-threatening complications associated with PV [1]. Here, we report a rare case of PV presenting as acute myocardial infarction (MI) and briefly discuss the applicability of cur...

L. monocytogenes is a foodborne psychrotrophic bacterial pathogen of special importance for minimally processed foods. In this work, it was enumerated in samples of surubim fish by MPN technique. The population of L. monocytogenes was estimated as < 0.012 MPN/cm(2) in fresh and < 0.03 MPN/g in minimally processed fish.

Atypical chronic myeloid leukemia (aCML) is a rare chronic myeloproliferative disorder characterized by leukocytosis, absence of Philadelphia chromosome or BCR-ABL rearrangement, and marked myeloid dysplasia. The diagnosis of aCML is difficult and challenging, more so if the initial presentation is with blast crisis. In the absence of characteristic mutational profile, blast crisis of aCML can ...

The pathogenesis of myeloproliferative disorder remains unknown, but there have been some experiments on murine myeloproliferative sarcoma induced by certain viruses. Myeloproliferative sarcoma virus which is well known among such viruses, causes myeloproliferative disorder in mice and today's work will reveal tumorigenicity of this virus in rats. Two groups of Jar-2 rats (31 young rats and 28 ...
