Myeloid neoplasia (formerly termed myeloproliferative disease) refers to all leukaemias originating from (non-lymphoid) haematopoietic stem cells, called common myeloid progenitor cells, which may differentiate to produce granulocytic, monocytic, erythrocytic and megakaryocytic lineages. Myeloid neoplasms are subclassified as myelodysplastic syndromes, acute myeloid leukaemiasand myeloproliferative neoplasms (formerly chronic myeloproliferative disease). | Myeloid neoplasia (formerly termed myeloproliferative disease) refers to all leukaemias originating from (non-lymphoid) haematopoietic stem cells, called common myeloid progenitor cells, which may differentiate to produce granulocytic, monocytic, erythrocytic and megakaryocytic lineages.
