Myelodysplastic syndrome is a closely related group of acquired bone marrow disorders characterized by ineffective and dysplastic hematopoiesis. These clonal disorders frequently progress to acute leukemia. Acute myelomonocytic leukemia with eosinophilia is characterized by an increase in abnormal eosinophils in the bone marrow, relatively good clinical course and inv (16) chromosomal abnormali...

INTRODUCTION Myelodysplastic syndromes encompass a heterogeneous group of clonal hematopoietic stem cell disorders characterized by ineffective hematopoiesis, refractory cytopenia and a tendency to progress toward acute myeloid leukemia. The accumulation of genetic alterations is closely associated with the progression of myelodysplastic syndromes toward acute myeloid leukemia. OBJECTIVE To i...

myelodysplastic syndromes (mds) are a group of hematological disorders ranging from chronic refractory anemia to leukemia. there are some reports about association of mds with autoimmune disorders and vasculitis. in this study we describe a patient with mds and vasculitis presenting with central nervous system (cns) involvement. a clinical response to immunosuppressive therapy was also observed...

Hemolytic anemia has been reported to occur in the setting of aortic stenosis and prosthetic heart valves, but much more rarely in association with obstructive hypertrophic cardiomyopathy (HC). Of the few descriptions of hemolytic anemia secondary to HC, all but one case involved bacterial endocarditis contributing to left ventricular outflow tract obstruction. We present the case of a 67-year-...

A 84-year-old woman with a long-standing history of progressive exertional dyspnea and fatigue was assessed for concomitant anemia. She also had coronary artery disease, chronic obstructive pulmonary disease, hypertension, and gout. Her hemoglobin was 109 g/L with a mean corpuscular volume of 76.1 fL and red blood cell distribution width (RDW) at 19.4%. White cell count including differential a...

A clinical case of a 67-year-old patient suffering from severe iron deficiency anemia, caused by gastric antral vascular ectasia (GAVE), is described. This type angiodysplasia characterized distinct endoscopic picture and rare cause bleeding. Endoscopic hemostasis considered the main method treatment, however, after argon plasma coagulation (APC), in our case, anemia recurred, required repeated...

Iron refractory iron deficiency anemia (IRIDA) is a recently described autosomal recessive disorder caused by mutations in TMPRSS6, the gene encoding matriptase-2. Patients have inappropriately high levels of hepcidin. Hypochromic microcytic anemia refractory to oral iron and only partially responsive to parenteral iron is the hallmark of this disorder. We report six patients from three unrelat...

BACKGROUND Pearson syndrome (PS) is a rare multisystem mitochondrial disorder of hematopoietic system, characterized by refractory sideroblastic anemia, pancytopenia, exocrine pancreatic insufficiency, and variable neurologic, hepatic, renal, and endocrine failure. CASE PRESENTATION We describe a six-month-old female infant with Pearson marrow syndrome who presented with neurological manifest...
