Archived elucemia the original PDF on 19 March Retrieved 19 December Wilhelm Ebstein introduced the term “acute leukemia” in to differentiate rapidly progressive and fatal leukemias from the more indolent chronic leukemias. Acute myeloid leukemia is a curable disease; the chance of cure for a specific person depends on a number of prognostic factors.

Bone marrow aspirationblood test leucmia. The first clue to a diagnosis of AML is typically an abnormal result on a complete blood count. If no further postremission or consolidation therapy is given, almost all people with AML will eventually relapse.

Monographs in Epidemiology and Biostatistics. Occupational chemical exposure to benzene and other aromatic organic solvents is controversial as a cause of AML.

Prognostic impact of karyotype and immunologic leucemiia in adult patients with de novo AML. Most signs and symptoms of AML are caused by the replacement of normal blood cells with leukemic cells. Services on Demand Journal. Annals of Internal Medicine. AML which arises from a pre-existing myelodysplastic syndrome MDS or myeloproliferative disease so-called secondary AML has a worse prognosisas does treatment-related AML arising after chemotherapy for another previous malignancy.

InAML became the first cancer genome to be fully sequenced.

Acute myeloid leukemia – Wikipedia

In straightforward cases, the presence of certain morphologic features such as Auer rods or specific flow cytometry results can distinguish AML from other leukemias; however, in the absence of such features, diagnosis may be more difficult. While some studies have suggested a link between occupational exposure to benzene and increased risk of AML, [13] others have suggested the attributable risk, if any, is slight.


In normal hematopoiesisthe myeloblast is an immature precursor of myeloid white blood cells; a normal myeloblast will gradually mature into a mature white blood cell. A hereditary risk for AML appears to exist. Cancer Genet Cytogenet ; These are prevalent, and potentially clinically relevant because of the availability of tyrosine kinase inhibitorssuch as imatinib and sunitinib that can block the activity of c-KIT pharmacologically. The first published description of a case of leukemia in medical literature dates towhen French physician Alfred-Armand-Louis-Marie Velpeau described a year-old florist who developed an illness characterized by fever, weakness, urinary stonesand substantial enlargement of the liver and spleen.

AML Acute panmyelosis with myelofibrosis Myeloid sarcoma. Velpeau noted the blood of this person had a consistency “like gruel”, and speculated the appearance of the blood was due to white corpuscles. The M3 subtype of AML, also known as acute promyelocytic leukemia APLis almost universally treated with the drug all- trans -retinoic acid ATRA in addition to induction chemotherapy, usually an anthracycline.

The early signs of AML are often vague and nonspecific, and may be similar to those of influenza or other common illnesses. Jeffrey 1 September Risk factors include smokingprevious chemotherapy or radiation therapymyelodysplastic syndromeand exposure to agida chemical benzene.

An important pathophysiological mechanism of leukemogenesis in AML is the epigenetic induction of dedifferentiation by genetic mutations that alter the function of epigenetic enzymes, such as the DNA demethylase TET2 and miepoide metabolic enzymes IDH1 and IDH2, [51] which lead to the generation of a novel oncometabolite, D hydroxyglutarate, which inhibits the leucemis of epigenetic enzymes such as TET2.

Rarely, Sweet’s syndromea paraneoplastic mieliode of the skin, can occur with AML. Diffuse cutaneous mastocytosis Erythrodermic mastocytosis Adult type of generalized eruption of cutaneous mastocytosis Urticaria pigmentosa Mast cell sarcoma Solitary mastocytoma. Lymph node swelling is rare in AML, in contrast to acute lymphoblastic leukemia.


Each of the WHO categories contains numerous descriptive subcategories of interest to the hematopathologist and oncologist ; mieloidee, most of the clinically significant information in the WHO schema is communicated via categorization into one of the subtypes listed below.

Mitelman F, Heim S. Marrow or blood is examined under light microscopyas well as flow cytometryto diagnose the presence of leukemia, to differentiate AML from other types of leukemia e.

Retrieved 18 March For good-prognosis leukemias i. In general, all remissions will fail without additional consolidation therapy. Two gauda mutations — NPM1 and biallelic CEBPA are associated with improved outcomes, especially in people with normal cytogenetics and are used in current risk stratification algorithms.

DNA extracted from leukemic cells were compared to unaffected skin. This category of AML occurs most often in elderly people and often has a worse prognosis. Acute myeloid leukemia AML is a cancer of the myeloid line of blood cellscharacterized by the rapid growth of abnormal cells that build up in the bone mieliide and blood and interfere with normal blood cells.

Bennett; he used the term “leucocythemia” to describe this pathological condition. High amounts of ionizing radiation exposure can increase the risk of Leucemiia. Fluorescent in situ hybridization performed on blood or bone marrow is often used for this purpose, as it readily identifies the chromosomal translocation [t 15;17 q22;q12 ;] leuucemia characterizes APL.

Much of the diversity and heterogeneity of AML is because leukemic transformation can occur at a number of different steps along the differentiation pathway. Mastocytoma Mast cell leukemia Mast cell sarcoma Systemic mastocytosis.
