A chloroma is a solid tumor composed of immature white blood cells called myeloid precursor cells.
Chloromas get their name from the Greek chloros (meaning green) since these tumors often have a green tint due to the presence of myeloperoxidase.

MIC2 expression was seen in leukemic blasts in 6 of 11 chloromas (55%) and 13 of 30 AML (43%) but rarely in myeloproliferative disorders, myelodysplastic syndromes, remission, and normal marrow.
We concluded that MIC2 is commonly expressed in leukemic blasts of AML and is not predictive of leukemic transformation from myeloproliferative disorders and myelodysplastic syndromes or chloroma formation.

Granulocytic sarcoma is a rare extramedullary collection of granulocytic cells, also known as chloroma.
In 1853, King initially called it chloroma, because typical forms have a green color caused by high levels of myeloperoxidase in these premature cells.
Granulocytic sarcoma (the preferred term, as not all lesions have the greenish tint) occurs primarily in 3-8% of all patients with acute/chronic myelogenous leukemia, but can also arise in patients with other myeloproliferative disorders, such as myelofibrosis with myeloid metaplasia, hypereosinophilic syndrome, polycythemia vera, and acute lymphoblastic leukemia.

Chloromas (also known as granulocytic sarcoma) are rare masses consisting of immature granulocytic cells.
Intracranially, chloroma may be purely intraparenchymal or may be dural based; the latter may be indistinguishable from meningioma (case 8).
Other leukemias may be associated, rarely, with intracerebral masses (nonchloroma) and like chloroma, symptoms are nonspecific, related to increased intracranial pressure or mass effect.
