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...

Although more than 90% systemic mastocytosis (SM) patients express gain of function mutations in the KIT receptor, recent next generation sequencing has revealed the presence of several additional genetic and epigenetic mutations in a subset of these patients, which confer poor prognosis and inferior overall survival. A clear understanding of how genetic and epigenetic mutations cooperate in re...

Hypomethylating drugs are useful and have been approved for the treatment of myelodysplastic syndromes (MDS) and Chronic Myelomonocytic Leukemia (CMML). However, phase 2 and 3 studies that assessed these agents in MDS, have included o patients with CMML, and there are just a few specific reports on CMML patients. is actually authorised for the treatment of CMML patients with 10 myeloproliferati...

The concurrence of myeloproliferative neoplasms (MPNs) and multiple sclerosis (MS) is unusual. We report five patients from a localized geographic area in Denmark with both MS and MPN; all the patients were diagnosed with MPNs in the years 2007-2012. We describe the patients' history and treatment. A potential link between MS and MPNs has not been previously recognized. This observation calls a...

Extensive fibrosis in myelodysplastic syndromes (MDS) is distinctly infrequent. Herein, we report three rare cases of hyperfibrotic MDS. This entity should be classified separately in the chronic myeloproliferative disease (CMPD)-MDS group due to variable clinical presentation and poor prognosis.

A female with suspected Down syndrome was born by vaginal delivery at 37 weeks 2 days’ gestation to a mother with a history of Type A2 gestational diabetes mellitus. Routine prenatal testing consisted of a non-invasive screening test for aneuploidy. Results, presented in Table 1, indicated an aneuploidy for trisomy of chromosome 21, indicating an increased risk for Down syndrome. Prenatal confi...

We report a case of non-sideroblastic refractory anaemia which evolved to a double lymphomyeloproliferative disorder. At presentation, bone marrow appearances and peripheral blood pancytopenia without myelomonocytosis were consistent with a diagnosis of non-sideroblastic refractory anaemia. Subsequently, the patient developed pronounced myelomonocytosis and lymphocytosis with prolymphocytes. Li...

Since serum tryptase levels are elevated in some patients with myeloproliferative disorders, we examined their utility in identifying a subset of patients with hypereosinophilic syndrome (HES) and an underlying myeloproliferative disorder. Elevated serum tryptase levels (> 11.5 ng/mL) were present in 9 of 15 patients with HES and were associated with other markers of myeloproliferation, includi...
