- UI:1008 - Acute myeloid leukemia with inv(16) and increased abnormal eosinophils

Tumors

- acute myeloid leukemia (acute myelogenous leukemia or AML) (5-10%)

  • M4-AML
    • M4eo-AML (M4-AML with marked eosinophilia) (all M4eo share 16q22 anomaly)
    • M4-AML without eosinophilia (20%)
  • M2-AML
  • M5-AML
  • frequent CNS involvement, according to some authors, in particular at relapse

- myelodysplastic syndromes (MDS)
