Acute megakaryocytic leukemia (AMegL) is a biologically heterogenous subtype of acute myeloid leukemia (AML) that arises from megakaryocytes. Improvements in the accuracy of diagnosing AMegL as well as interest in the molecular analysis of leukemias have led to an increased amount of data available on this rare AML subtype.

A betegség diagnosztizálása kétféleképpen történhet. Az egyik lehetőség, hogy a beteg tünetei - például a fáradékonyság, a vérszegénység miatti panaszok, a bőrvérzés vagy a fertőzésekre való hajlam - miatt keresi föl az orvost. A másik eset, amikor a páciens nem meghatározott tünetekkel fordul a doktorhoz, hanem egy általános vizsgálat során észlelnek nála
