A family is described in which three male members died in early infancy with severe thrombocytopenia and a fourth in adolescence with aplastic anaemia. One child was investigated in detail and shown to have amegakaryocytic thrombocytopenia, progressing to pancytopenia as a result of bone marrow hypoplasia. His associated congenital abnormalities differed from those described in Fanconi's aplast...

totally implantable venous access devices (tivad) or implantable catheter ports are devices which can be implanted subcutaneously. they enable prolonged and repeated access to the vascular system, into the peritoneal cavity or intravertebral space. this device is particularly useful for repeated medical injection, for blood sampling or transfusion of blood and blood derivatives and for total pa...

Acquired amegakaryocytic thrombocytopenic purpuria (AATP) is an unusual hematologic disorder characterized by thrombocytopenia resulting from an unexplained reduction in the number of bone marrow megakaryocytes in the presence of otherwise normal hematopoiesis in the bone marrow [1]. The exact prevalence of acquired amegakaryocytic thrombocytopenia is unknown due to its very rare incidence. Aro...

To elucidate the usefulness of beta-thromboglobulin (beta TG) in the differentiation of the mechanism of thrombocytopenia, plasma beta TG concentration was measured in one patient with amegakaryocytic thrombocytopenia, four patients with autoimmune thrombocytopenia (ATP), two patients with thrombotic thrombocytopenia (TTP), and one patient with thrombocytopenia secondary to disseminated intrava...

Congenital amegakaryocytic thrombocytopenia (CAMT) is a rare, autosomal recessive disorder induced by mutations of the gene coding for thrombopoietin (TPO) receptor (c-MPL) despite high levels of serum TPO. Patients initially present with isolated thrombocytopenia that subsequently progresses into pancytopenia. Although the mechanisms leading to aplasia are unknown, the age of onset has been re...

To elucidate the usefulness of $-thrombocoagulation (DIC). Plasma $TG was not globulin (fiTG) in the differentiation of the measurable in amegakaryocytic thrombomechanism of thrombocytopenia, plasma cytopenia, was normal in ATP, and was TG concentration was measured in one increased in TTP and DIC. These data mdipatient with amegakaryocytic thrombocycate that in thrombocytopenic patients, topen...

We report a rare case of myelodysplastic syndrome that presented early as amegakaryocytic thrombocytopenia in a collodion baby, which is a rare congenital disorder characterized by thick, taut membrane resembling oiled parchment or collodion, which is subsequently shed. To our knowledge, this is the first reported case of a collodion baby who presented with amegakaryocytic thrombocytopenia and ...

amegakaryocytic thrombocytopenia (amt) is a rare cause of acquired thrombocytopenia. the pathogenesis and treatment of amt is not clearly known. here we demonstrate a 50-year-old man presented with the clinical manifestations of severe thrombocytopenia (7000 platelets/µl) with a marked decrease to absent of megakaryocytes in the bone marrow. the patient did not respond to intravenous immunoglob...
