(51,69) Unlike AML
M4Eo, where granules are enlarged, the granules in chronic eosinophilic leukemia associated with FIP1L1-PDGFRA are commonly small and sparse (Figure 2, A and B).

M4eo, atypical cytomorphology, atypical immunophenotype, atypical additional chromosomal rearrangements and low white blood cell count: a study on 162 patients Leukemia 2007;21:725-31.
Two patients had AL (one type B, common; and one biphenotypic), and 105 had acute myeloid leukemia: 1 with French-American-British subtype Mo, 11 with subtype M1, 13 with subtype M2, 65 with subtype M3, 4 with subtype M4, 2 with subtype
M4Eo, 5 with subtype M5, 2 with subtype M6, 1 who was not classified, and 1 with subtype M1 at relapse.
Patients with t(8; 21) frequently present with the French-American-British (FAB) morphologic subtype M2 or acute myeloid leukemia with differentiation, while patients with inv(16) more often are diagnosed with FAB subtype
M4Eo or acute myelomonocytic leukemia with eosinophilia.
