chloroma leukemia radiology

The term was coined due to the greenish hue of the skin from the myeloperoxidases made by the granulocytes. Intraaxial brain lesions are rare, and can mimic infection or primary neoplasm. The patient went on to have a resection which histologically confirmed chloroma (also known as a granulocytic sarcoma or myeloid sarcoma) of the occipital bone. Biopsy of the mass revealed chloroma. Some years ago, there was a tendency to regard chloroma as being of either a myeloid or a lymphoid type, but the general consensus of present opinion is that practically all cases are myeloid in character, the lymphoid cases being rare or non-existent.

In the fifth, an elderly patient developed a bone lesion during a blastic crisis while under treatment for chronic myelogenous leukemia. Two patients exhibited chloroma as the sole manifestation of their disease during bone marrow remission. Chloroma most often develops in the setting of acute myeloid leukemia (AML), but it can occur in association with chronic myeloid leukemia during the accelerated phase, myelodysplastic syndrome, and, rarely, in the absence of marrow involvement 1, 2, 3, 4.Chloroma occurs in approximately 10% of patients with AML 2, 5, 6.The clinical manifestations of chloromas are diverse, given their … Granulocytic sarcoma (chloroma) is a solid tumor of mye­ logenous cells seen in patients with acute or chronic myelo­ genous leukemia [1, 3-13].

The morphology and cytochemistry were consistent with acute myeloid leukemia. Radiology, Eberhard-Karls-University Tübingen, Tübingen, Germany. Cancer 2012; 118:112. Chloroma may be found in several extracranial sites. It is usually associated with myeloproliferative disorders but its appearance may precede the onset of leukaemia. 4, 5 Conversely, Pui et al (1994) found that of children with AML, only 4.7% had an identifiable chloroma. AJR 1996;17:1592-1594. MRI is the method that best characterizes this lesion. Chloroma may be found in several extracranial sites. Since 1888 approximately 27 cases have been reported (table). 3 Five decades later, the relationship of MS to acute leukemia was identified. It is a rare condition, most often associated with acute myeloid leukemia (AML), although in some rare cases it may present in nonleukemic patients. Myeloid sarcoma is an extramedullary tumor of immature granulocytic cells. (PMID: 8115614) In four cases, a chloroma was the initial manifestation of a systemic disease.

Author information: (1)Klinik und Poliklinik für Radiologie, Johannes Gutenberg Universität Mainz. On T1-weighted MR images, the lesion was isointense with gray matter, and enhanced homogeneously. Nests of granulocytic tumor cells in patients who have myelogenous leukemia are termed chloromas. Abstract A patient with a history of essential thrombocytosis presented with diffuse skeletal pain and restricted motion of the left shoulder. Intramedullary disease may mimic skull base osteomyelitis or metastasis. Name "chloroma" coined in 1853 by King because of its green color ("A case of chloroma" Monthly J Med 1853;18:97) Green color caused by the presence of myeloperoxidase. Orbital myeloid sarcoma (chloroma) as an initial symptom of acute myeloid leukemia (AML), is a rare medical condition. Cytogenetic profile of patients with acute myeloid leukemia and central nervous system disease. Granulocytic sarcoma (chloroma) is a rare tumor almost always associated with leukemia. Granulocytic Sarcoma is also known as myeloid sarcoma, chloroma, extramedullary myeloblastoma, and extramedullary myeloid tumor. In none of these was the condition definitely monocytic; in 7 it was lymphocytic and in the rest myeloid.

Shihadeh F, Reed V, Faderl S, et al. A unique pattern of central nervous system leukemia in acute myelomonocytic leukemia associated with inv(16)(p13q22). Background. In 1885, Recklinghausen first associated chloroma and leukemia and the relationship was conclusively proved by Dock and Warthin. Chloroma is a rare extramedullary presentation. Leukemia cutis is the infiltration of neoplastic leukocytes or their precursors into the epidermis, the dermis, or the subcutis, resulting in clinically identifiable cutaneous lesions.

Radiology 190:698–702 PubMed Google Scholar 4. Br J Radiol. Chloroma, also know as granulocytic sa rcoma, is a localized extramedullary tumor composed of malignant cells of the myeloi d cell line. Chloroma, also called Granulocytic Sarcoma or Myeloid Sarcoma, is a rare malignant extra-medullary neoplasm of myeloid precursor cells. This intracerebellar chloroma arose after autologous bone marrow transplantation in a 29-year-old woman with leukemia. An isolated chloroma discovered in a patient with a remote history of AML obligates a diagnosis of bone marrow relapse until proven otherwise because primary lesions without underlying systemic leukemia are so rare; indeed, only 154 cases have been reported since 1965.
