Abstractor Notes

Acute myeloid leukemia with minimal differentiation is part of the Acute myeloid leukemia (AML) lineage table in the WHO 5th edition of Hematolymphoid Tumors. (See Appendix B in the Hematopoietic Manual, Table B6)

The blood and bone marrow are always invovled.

If this leukemia and myeloid sarcoma (9930/3) occur during the same clinical workup, this is one primary, the leukemia.

If the myeloid sarcoma occurs after the diagnosis of the leukemia, that is a manifestation of the leukemia and is the same primary.

Diagnostic Confirmation

This histology can be determined by positive histology (including peripheral blood) with or without genetics and/or immunophenotyping. Review the Definitive Diagnostic Methods, Immunophenotyping and Genetics Data sections below, and the instructions in the Hematopoietic Manual for further guidance on assigning Diagnostic confirmation.
