Synonyms
In the old literature, the condition was frequently termed “chloroma,” “extramedullary acute myeloid leukemia,” “extramedullary myeloid tumor,” or “granulocytic sarcoma.” All these items refer to the histogenesis of the tumor except the one “chloroma” that points to the green color on gross examination produced by myeloperoxidase (MPO) oxidation.
Definition
According to the Revised fourth edition of the WHO Classification of Tumors of Hematopoietic and Lymphoid Tissues (Swerdlow et al. 2017), myeloid sarcoma (MS) (ICD-O code 9930/3) is “a tumour mass consisting of myeloblasts, monoblasts or haematopoietic precursors occurring at an anatomical site other than the bone marrow.”
