The association of chloroma with leukemic disease or myeloproliferative disorders is limited to isolated case reports. Neurological symptoms may result from the local accumulation of malignant cells in or near the brain (chloroma), infection, hemorrhage, or … Diagnosis: Chloroma of epidural space Key points AKA granulocytic sarcoma, extramedullary myeloblastoma.

SELIGMAN~ An unusual case of granulocytic sarcoma (chloroma) of the parenchyma the brain occurring in a patient with acute myelocytic leukemia in remission is described and the literature reviewed. Nests of granulocytic tumor cells in patients who have myelogenous leukemia are termed chloromas. We present the magnetic resonance (MR) findings of granulocytic sarcoma (chloroma) in two leukemic patients who presented with masses in the cerebellopontine angle and in the cavernous and the sphenoid sinuses. Yet most patients that relapsed or remained with chloroma after chemotherapy are in the RT cohort (90%). Introduction. In patients Nests of granulocytic tumor cells in patients who have myelogenous leukemia are termed chloromas. Granulocytic sarcoma occurs primarily in patients with acute myelogenous leukemia and may also arise in patients with other myeloproliferative disorders, but rarely in patients with acute lymphoblastic leukemia (ALL).

Granulocytic sarcoma (chloroma), a rare tumor usually associated with myelogenous leukemia, is capable of invading the meninges or brain parenchyma. Called also granulocytic sarcoma. Chordoma happens most often in adults between 40 and 60, though it can happen at any age. Soon thereafter, he complained of pain in his left buttock radiating into his left posterior thigh.

A myeloid sarcoma (chloroma, granulocytic sarcoma,: 744 extramedullary myeloid tumor), is a solid tumor composed of immature white blood cells 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 [4] RASHMI M NAGARAJU, BHIMARAO (2015) Chloroma of Orbit: A Rare Initial Presentation in A Case of Acute Myeloid Leukemia.

Myeloid sarcoma (MS), also known as granulocytic sarcoma or chloroma, is a solid tumor of extramedullary localization composed of malignant primitive myeloid cells.1 A first mention of the pathology was found in 1811 by Burns and later called chloroma on account of its typical green appearance caused by the presence of the enzyme myeloperoxidase in the granules of the … Howard SC, Gajjar A, Ribeiro RC, et al.
