Juvenile myelomonocytic leukemia (JMML) is a myelodysplastic and myeloproliferative disorder. [9] [26] [3] The diagnostic criteria were originally laid down by Neimeyer et al. in 1997 [27] and 1998 and were incorporated in the WHO classification in 2008. [28]

Juvenile myelomonocytic leukemia (JMML) is a form of leukemia in which myelomonocytic cells are overproduced. It is sometimes considered a myeloproliferative neoplasm. It is rare and most commonly occurs in children under the age of four. In JMML, the myelomonocytic cells produced by the bone marrow and invade the spleen, lungs, and intestines ...
The FAB criteria for diagnosis are as follows: [21] Monocyte count >1x10 9 /L; 0–19% blasts in bone marrow <5% blasts in peripheral blood; The FAB also arbitrarily categorises CMML into myelodysplastic-like and myeloproliferative-like groups. A white blood count of 13x10 9 is used as a cut-off to differentiate the two. [12]
Importantly, however, the clinical and laboratory phenotype resembles juvenile myelomonocytic leukemia. The high fatality rate of this childhood blood cancer puts it in sharp contrast when compared to the relatively benign and chronic course of RALD. Approximately 15-30% of patients diagnosed with JMML have somatic, activating RAS mutations.
Criteria for AMML is confirmed if the myeloblasts and promonocytes in the bone marrow are greater than 20 percent. It can also be confirmed if the blood monocytes is 5x10 9 /L or higher. [ 9 ] Testing available to diagnosis AML includes a complete blood count which is characterized by blood that is taken from the vein in the arm to test for ...
Acute monocytic leukemia (AMoL, or AML-M5) [2] is a type of acute myeloid leukemia. In AML-M5 >80% of the leukemic cells are of monocytic lineage. [3] This cancer is characterized by a dominance of monocytes in the bone marrow. There is an overproduction of monocytes that the body does not need in the periphery.
Acute lymphoblastic leukemia (ALL) 4.0% Acute myeloid leukemia (AML) 8.7% Chronic lymphocytic leukemia (CLL) sorted under lymphomas according to current WHO classification; called small lymphocytic lymphoma (SLL) when leukemic cells are absent. 10.2% Chronic myelogenous leukemia (CML) 3.7% Acute monocytic leukemia (AMoL) 0.7% Other leukemias 3.1%
