The tumour is most commonly located in the skull, orbits and sinuses. Extracranial tumours occur mainly in the soft tissues of the body and bone involvement is uncommonly seen and is almost invariably lytic in nature:.

In 1966, Rappaport noted that 30% of chloromas were not green2 and renamed these tumours granulocytic sarcoma. In none of these was the condition definitely monocytic; in 7 it was lymphocytic and in the rest myeloid. Holmes R, Keating MJ, Cork A, et al. Unravelling Chloroma: Review of Imaging Findings. Granulocytic sarcoma (chloroma) is a rare solid tumor of myelogenous stem cells, usually appearing in pa- tients with acute myelogenous leukemia … It is a rare condition, most often associated with acute myeloid leukemia (AML), although in some rare cases it may present in nonleukemic patients. Granulocytic sarcoma (chloroma) is a solid tumor of mye­ logenous cells seen in patients with acute or chronic myelo­ genous leukemia [1, 3-13]. Granulocytic sarcoma (chloroma) is a rare tumor almost always associated with leukemia. It occurs most frequently second-ary to a history of myelogenous leukemia as ex tramedullary relapse. This intracerebellar chloroma arose after autologous bone marrow transplantation in a 29-year-old woman with leukemia. Cytogenetic profile of patients with acute myeloid leukemia and central nervous system disease. Two patients exhibited chloroma as the sole manifestation of their disease during bone marrow remission. LEUKEMIA AND PLASMA CELL NEOPLASMS ANTHONY A. MANCUSO KEY POINTS Plasma cell tumors and leukemia may present as primarily intramedullary and extramedullary processes in the head and neck. Chloroma is a term used to describe single or multiple areas of skin involvement by chronic or acute myelogenous leukemia (Figure 1). Intramedullary disease may mimic skull base osteomyelitis or metastasis. The rate of occurrence is approx­ imately 3-9% o~ patients with acute or chronic myelogenous leukemia [12, 13]. Skeletal manifestations of chloroma were reviewed in five patients. In 1811, Allen Burns first reported this as a green tumour involving the orbit.1 The characteristic green colour is derived from the enzyme myeloperoxidase (MPO). The morphology and cytochemistry were consistent with acute myeloid leukemia. New treatment regimens, Lymph nodes, subcutaneous tissues, peritoneum, … [2] Parker et al. anders@radiologie.klinik.uni-mainz.de Six cases of granulocytic sarcoma are presented. A chloroma is a rare, extramedullary tumor of immature myeloid cells. It was first described in 1811 1 and later named “chloroma” by King 2 in 1853 because of its green color caused by the presence of myeloperoxidase (MPO). Radiology, Eberhard-Karls-University Tübingen, Tübingen, Germany. It is a rare solid tumor composed of primitive precursors of the granulocytic series of white blood cells that include myeloblasts, promyelocytes, and myelocytes The tumor is an extramedullary manifestation of acute myeloid leukemia (AML). The term "granulocytic sarcoma" was used by Rappaport to describe tumors of granulocytic origina. 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. Nests of granulocytic tumor cells in patients who have myelogenous leukemia are termed chloromas. It consists of immature cells of the granulocytic series. OBJECTIVE. Neurologic examination was unremarkable. A mediastinal chloroma and a tumor of the submandibular gland were observed with two patients as single sign of acute myeloic leukaemia. A unique pattern of central nervous system leukemia in acute myelomonocytic leukemia associated with inv(16)(p13q22). The four major leukemia types are acute myeloid leukemia (AML), chronic myeloid leukemia (CML), acute ... chloroma, or myeloblastoma. 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. Magnetic resonance imaging (MRI) of the left glenohumeral joint showed a soft tissue mass that displaced the rotator cuff. On T1-weighted MR images, the lesion was isointense with gray matter, and enhanced homogeneously. In 1885, Recklinghausen first associated chloroma and leukemia and the relationship was conclusively proved by Dock and Warthin. Plasma cell tumors may not be systemic at the time of head and neck presentation. It is usually associated with myeloproliferative disorders but its appearance may precede the onset of leukaemia. Shihadeh F, Reed V, Faderl S, et al. Biopsy of the mass revealed chloroma. Zimmermann LE, Font RL (1975) Ophthalmologic manifestations of granulocytic sarcoma (myeloid sarcoma or chloroma). Soon thereafter, he complained of pain in his left buttock radiating into his left posterior thigh. 3 Five decades later, the relationship of MS to acute leukemia was identified. Lymph nodes, subcutaneous tissues, peritoneum, pleural space, pelvis, and portal hepatis were involved. Author information: (1)Klinik und Poliklinik für Radiologie, Johannes Gutenberg Universität Mainz. MRI is the method that best characterizes this lesion. Chloroma is a rare extramedullary presentation. Eight cases of chloroma seen on CT were reviewed. (PMID: 8115614) 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 … Abstract A patient with a history of essential thrombocytosis presented with diffuse skeletal pain and restricted motion of the left shoulder. Congenital leukemia is rare. Granulocytic Sarcoma is also known as myeloid sarcoma, chloroma, extramedullary myeloblastoma, and extramedullary myeloid tumor. Van Landeghem, P. Smeets1 Key-word: Chloroma 1. 2017 Apr 26;:20160710 Authors: Singh A, Kumar P, Chandrashekhara SH, Kumar A Abstract Chloroma refers to the extramedullary proliferation of immature myeloid precursors occurring in a gamut of myeloproliferative and myelodysplastic conditions; acute myeloid leukemia (AML), being the commonest. 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. Blood 1985; 65:1071. In the fifth, an elderly patient developed a bone lesion during a blastic crisis while under treatment for chronic myelogenous leukemia. In four cases, a chloroma was the initial manifestation of a systemic disease. Chloroma, also know as granulocytic sa rcoma, is a localized extramedullary tumor composed of malignant cells of the myeloi d cell line. MR features of an intracellular chloroma. Chloroma may be found in several extracranial sites. Eight cases of chloroma seen on CT were reviewed.

Department of Radiology, Ghent University Hospital, Ghent, Belgium Background: A 53-year-old female patient known with diagnosis of acute myeloid leukemia (originating from a precursor phase of myelodysplasia) was seen during follow-up at our hospital. § Division of Pediatric Radiology, Duke University, Durham, NC. Chloroma may be found in several extracranial sites. 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. Cancer 2012; 118:112.

[4] RASHMI M NAGARAJU, BHIMARAO (2015) Chloroma of Orbit: A Rare Initial Presentation in A Case of Acute Myeloid Leukemia. A 23-year-old man with recurrent acute myeloid leukemia (AML) underwent successful reinduction and was judged posttherapy to be in complete remission. We present an unusual case of a granulocytic sarcoma (chloroma) of the sacrum which predated the initial clinical manifestation of acute myelogenous leukemia. @article{osti_5678447, title = {Granulocytic sarcoma (chloroma): CT manifestations}, author = {Pomeranz, S J and Hawkins, H H and Towbin, R and Lisberg, W N and Clark, R A}, abstractNote = {Nests of granulocytic tumor cells in patients who have myelogeneous leukemia are termed chloromas. 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. 4, 5 Conversely, Pui et al (1994) found that of children with AML, only 4.7% had an identifiable chloroma. The term was coined due to the greenish hue of the skin from the myeloperoxidases made by the granulocytes.
