A mediastinal chloroma and a tumor of the submandibular gland were observed with two patients as single sign of acute myeloic leukaemia. 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).

OBJECTIVE. Cytogenetic profile of patients with acute myeloid leukemia and central nervous system disease. Chloroma is a rare extramedullary presentation. It consists of immature cells of the granulocytic series. This intracerebellar chloroma arose after autologous bone marrow transplantation in a 29-year-old woman with leukemia. In four cases, a chloroma was the initial manifestation of a systemic disease.

Extracranial tumours occur mainly in the soft tissues of the body and bone involvement is uncommonly seen and is almost invariably lytic in nature:. 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. 4, 5 Conversely, Pui et al (1994) found that of children with AML, only 4.7% had an identifiable chloroma. In none of these was the condition definitely monocytic; in 7 it was lymphocytic and in the rest myeloid. Neurologic examination was unremarkable. MRI is the method that best characterizes this lesion. Chloroma, also called Granulocytic Sarcoma or Myeloid Sarcoma, is a rare malignant extra-medullary neoplasm of myeloid precursor cells. 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. The term chloroma arising from the frequent, ... Muhammad Bin Zulfiqar PGR IV New Radiology Department SHL/SIMS radiombz@gmail.com Biopsy of the mass revealed chloroma. Plasma cell tumors may not be systemic at the time of head and neck presentation. A chloroma is a rare, extramedullary tumor of immature myeloid cells. The morphology and cytochemistry were consistent with acute myeloid leukemia. We present an unusual case of a granulocytic sarcoma (chloroma) of the sacrum which predated the initial clinical manifestation of acute myelogenous leukemia. 3 Five decades later, the relationship of MS to acute leukemia was identified. Congenital leukemia is rare. Lymph nodes, subcutaneous tissues, peritoneum, pleural space, pelvis, and portal hepatis were involved. International Journal of Anatomy, Radiology and Surgery, Vol-4(3): 27-29 In 1966, Rappaport noted that 30% of chloromas were not green2 and renamed these tumours granulocytic sarcoma. Van Landeghem, P. Smeets1 Key-word: Chloroma 1. Chloroma may be found in several extracranial sites. Granulocytic sarcoma (chloroma) is an unusual tumour usually seen in cases of myelogenous leukemia. 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. 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. It occurs most frequently second-ary to a history of myelogenous leukemia as ex tramedullary relapse. Eight cases of chloroma seen on CT were reviewed. Myeloid sarcoma is an extramedullary tumor of immature granulocytic cells. Soon thereafter, he complained of pain in his left buttock radiating into his left posterior thigh. 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 … In the fifth, an elderly patient developed a bone lesion during a blastic crisis while under treatment for chronic 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.

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). AJR 1996;17:1592-1594. Radiology 190:698–702 PubMed Google Scholar 4. 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. Two patients exhibited chloroma as the sole manifestation of their disease during bone marrow remission. 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. Magnetic resonance imaging (MRI) of the left glenohumeral joint showed a soft tissue mass that displaced the rotator cuff. (PMID: 8115614) Blood 1985; 65:1071. Granulocytic Sarcoma is also known as myeloid sarcoma, chloroma, extramedullary myeloblastoma, and extramedullary myeloid tumor. The tumour is most commonly located in the skull, orbits and sinuses. 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). It is usually associated with myelo-proliferative disorders but its appearance may precede the onset of leukaemia. EXTRAMEDULLARY CHLOROMA B. Arys, A.
