A form of acute myeloid leukemia that is either comprised of more than 80% of monoblasts or 30-80% monoblasts with (pro)monocytic differentiation. It presents with asthenia, pallor, fever, and dizziness. Specific features include hyperleukocytosis, propensity for extramedullary infiltrates, coagulation abnormalities including disseminated intravascular coagulation and neurological disorders. Leukemia cutis and gingival infiltration can also be seen. A characteristic translocation observed is t(9;11).
