leukaemia (AMKL) is a rare subtype of acute myeloid leukaemia (AML). It is more common in children than in adults. In children with Down syndrome, AMKL is the most common type of AML. AMKL is characterised by a presence of ≥20% of megakaryoblasts of which 50% or more are of megakaryocyte lineage, meaning that they have developed from

Bruising or bleeding easily. Acute megakaryoblastic leukemia. In this blood smear from a pancytopenic dog (non-regenerative anemia, neutropenia, thrombocytopenia), there are several large blasts.

We have associated certain patterns of antigen expression with AML in dogs. Far less is known in cats (way fewer antibodies available) and horses (way fewer cases with AML). For positive staining reactions, we use a cut-off of ≥20% (beyond the isotype control) except for CD34, in which we use ≥5% (not expressed in normal canine blood).

The patient manifested acute coronary syndrome. Even after emergent percutaneous coronary intervention, his performance status remained poor, so no chemotherapy against leukemia was given. Megakaryoblastic leukemia (M7) is the designation proposed by the Animal Leukemia Study Group for myeloproliferative neoplasms of megakaryocytic lineage.
