Acquired amegakaryocytic thrombocytopenic purpura - An underdiagnosed entity
نویسنده
چکیده
Acquired Amegakaryocytic Thrombocytopenic Purpura (AATP) is a rare cause of thrombocytopenia presenting over a wide age group with symptoms of bleeding and bone marrow showing isolated absence of megakaryocytes in an otherwise normal marrow. Here, we report a case of AATP in a three year old female child who was then treated with anti thymocyte globulin successfully. We report this case because of it’s under diagnosis or misdiagnosis as immune thrombocytopenia (ITP) in most of the cases. We also review the literature regarding the pathogenesis and treatment of this

Danazol: An Effective Option in Acquired Amegakaryocytic Thrombocytopaenic Purpura
Acquired amegakaryocytic thrombocytopaenic purpura (AATP) is a rare haematological condition characterised by isolated thrombocytopaenia with normal other cell lines. It is often initially misdiagnosed as immune thrombocytopaenic purpura but has characteristic bone marrow findings of reduced megakaryocyte numbers. The optimal treatment of AATP is not clearly defined but revolves around immunosu...
متن کاملAcquired Amegakaryocytic Thrombocytopenia in a Child: A Very Rare Case
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...
متن کاملAcquired amegakaryocytic thrombocytopenia previously diagnosed as idiopathic thrombocytopenic purpura in a patient with hepatitis C virus infection
We report the first case of a patient with hepatitis C virus (HCV) infection and idiopathic thrombocytopenic purpura (ITP), who later developed acquired amegakaryocytic thrombocytopenia (AAMT), with autoantibodies to the thrombopoietin (TPO) receptor (c-Mpl). A 64-year-old woman, with chronic hepatitis C, developed severe thrombocytopenia and was diagnosed with ITP. She died of liver failure. A...
متن کاملAcquired amegakaryocytic thrombocytopenic purpura with humoral inhibitory factor for megakaryocyte colony formation.
A 67-year-old man with thrombocytopenia, and amegakaryocytic but otherwise normal bone marrow, was evaluated. Antibody against thrombocytes was negative and the half-life of thrombocytes was normal. In vitro clonal culture of the patient's bone marrow cells yielded no megakaryocyte colony with normal granulocyte-macrophage and erythroid colony formation. Megakaryocyte colony formation of the co...
متن کاملInherited Thrombocytopenia with a Different Type of Gene Mutation: A Brief Literature Review and Two Case Studies
Hereditary thrombocytopenias are rare bleeding disorders, which cause a deficiency of platelets in early infancy. This group of disorders is sometimes associated with abnormal phenotypes, like absence of radius. Diagnosis of this type of thrombocytopenia is usually difficult; other causes of thrombocytopenia, such as immune disorders and infections, must be ruled out. The symptoms of hereditary...
