A myeloid sarcoma (chloroma, granulocytic sarcoma,[1]: 744 extramedullary myeloid tumor) is a solid tumor composed of immature white blood cells[2] called myeloblasts. A chloroma is an extramedullary manifestation of acute myeloid leukemia; in other words, it is a solid collection of leukemic cells occurring outside of the bone marrow.
