Answer

Answer

Myeloid sarcoma is an extramedullary tumor mass consisting of myeloid blasts that efface the tissue architecture. [8]  The latter feature is particularly important to distinguish myeloid sarcoma from tissue infiltration by leukemic blasts in acute myeloid leukemia (AML) patients; AML tissue infiltrates do not form tumoral masses that efface the underlying architecture.

Associated disorders include granulocytic sarcoma (ie, chloroma), monoblastic/monocytic sarcoma, and erythroid sarcoma. [8]
