Myeloid sarcoma, also known as chloroma, extramedullary myeloid tumor or granulocytic sarcoma
, is an extramedullary tumor mass consisting of immature myeloid cells and/or myeloblasts.
(GS) is a localized tumor formed by primitive myeloid cells at an extra medullary site.
Previous nomenclature for myeloid sarcoma included granulocytic sarcoma
, myeloblastoma, extramedullary myeloid tumor, and chloroma.

Intraoral granulocytic sarcoma
presenting as multiple maxillary and mandibular masses: a case report and literature review.
(GS) is the tumoral infiltration of extramedullary sites with immature myeloid precursor cells; it is associated with 3%-8% of acute myeloid leukemia (AML) cases and rarely with chronic myeloproliferative disorders 11].
Subsequent biopsy of the middle ear exudate proved pre-B-cell ALL recurrence, consistent with a granulocytic sarcoma
Leukemia involvement of the central nervous system most commonly presents as meningeal leukemia; intracerebral granulocytic sarcoma
(IGS) is rare.
s case report entitled, Cerebellar granulocytic sarcoma
: A case report (2012; 19: 177-180), (1) provides an opportunity for me to remind physicians that short-course megadose methylprednisolone (MDMP: 30 mg/kg for 3 d, then 20 mg/kg for 4 d each dose administered over the course of 10-15 min intravenously or orally; calculated dose of powder put into a spoon and then covered with honey and administered before 0600), has been effectively used for the treatment of granulocytic sarcoma
(GS) (2), (3), (4), (5).
(chloroma) is a tumor composed of immature myeloid/monocytic precursors occurring in an extramedullary site (1).

Histochemical staining for myeloperoxidase and lysozyme in the neoplastic cells helps to confirm the diagnosis of granulocytic sarcoma
