Granulocytic sarcoma of the orbit, also known as chloroma, is an extramedullary form of myelogenous leukemia. Granulocytic sarcoma is an uncommon manifestation of myelogenous leukemias in which focal masses of immature myeloid cells from the granulocytic lineage infiltrate bone and soft tissue. Multiple lesions were found in 6 patients. Orbital tumors in children are very rare and radiologic image, as magnetic resonance, is extremely important for correct diagnosis. Orbital biopsy documented an unusual presentation of childhood pseudotumor. International Journal of Anatomy, Radiology … Orbital granulocytic sarcoma (chloroma), a rare tumor of immature myeloid cells, has nonspecific clinical and radiological features that make it a diagnostic challenge. It is most common in the pediatric population and may present at any time in the course of the disease, either concurrently with the onset of leukemia or during a remission or relapse. Orbital disease secondary to acute lymphoblastic leukemia (ALL) is rare, particularly in the adult population. RASHMI M NAGARAJU, BHIMARAO (2015) Chloroma of Orbit: A Rare Initial Presentation in A Case of Acute Myeloid Leukemia. The skull and orbital regions are especially affected, giving the so-called “chloromatous facies.” J Comput Assist Tomogr 1987;11 :938-941 3. PMID: 22177127 [PubMed - indexed for MEDLINE] Sixteen cases were referred to the department of hematology for treatment. 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). AIM Orbital granulocytic sarcoma is a localised tumour composed of cells of myeloid origin. Occurrence is more common in acute rather than chronic myelogenous leukemia. It consists of immature cells of the granulocytic series. The orbits develop throughout childhood and congenital absence of the globe, enucleation, or radiotherapy results in failure of normal orbital growth. ... Kevin M. Rice, MD is the president of Global Radiology CME . The diagnosis of orbital chloroma can be established by radiology and hematological examinations. This constitutes about 3/5 th of all the orbital pathologies out of which about 85% is due to the thyroid ophthalmopathy. Chloroma (myeloid or granulocytic sarcoma) is a rare type of tumour comprising immature granulocytic cells. The tumor extends into the left ethmoid sinus. In 4 following cases, 2 cases were died within 3 months. Orbital rhabdomyosarcoma. The diagnosis of orbital chloroma can be established by radiology and hematological examinations. Radiologic images are essential for determine specific diagnosis in most cases of pediatric orbital pathology. Kao SCS, Yuh WTC. (a) Axial CT image in soft-tissue window reveals large irregular soft-tissue mass in the left orbit.The mass is poor-demarcated and heterogeneous density. Pediatr Radiol 1995; 25:488-489 [Google Scholar] The mass sizes varied from a mean diameter of 1.3 to 5.8 cm (average, 2.6 cm). It is most common in the pediatric population and may present at any time in the course of the disease, either concurrently with the onset of leukemia or during a remission or relapse. This tumor can be treated by chemotherapy and radiotherapy. In 1966, Rappaport noted that 30% of chloromas were not green2 and renamed these tumours granulocytic sarcoma. cytic sarcoma (chloroma): CT Manifestations. The masses were most commonly located in the orbital cavity (n=8); other locations included lymph nodes (n=5) and palatine/pharyngeal/lingual tonsils (n=3). There was diffuse hyperostosis of the … Inflammatory condition can be divided into acute, subacute or chronic. The orbit is a particularly frequent site of involvement. Orbital blowout fracture and vitreous hemorrhage All Posts ... •1853: King initially called it chloroma, because typical forms have a green color caused by high levels of myeloperoxidase in the immature cells. Granulocytic sarcoma, also known as chloroma or extramedullary myeloblastoma, is a rare solid tumor composed of primitive precursors of the granulocytic series of WBC that include myeloblasts, promyelocytes, and myelocytes [].This tumor was first described by Burns in 1811. Infectious orbital cellulitis usually bacterial extended posterior to orbital septum meningitis cavernous sinus thrombosis staphylococci. Abstract Granulocytic sarcoma is an uncommon manifestation of myelogenous leukemias in which focal masses of immature myeloid cells from the granulocytic lineage infiltrate bone and soft tissue. The tumors are slow growing with periods of growth and dormancy,97, 98 some may regress completely.99, 100 In an analysis of affected orbital locations, 48% involved the orbital optic nerve, 24% the orbital and intracranial optic nerve, 10% intracranial optic nerve and chiasm, and just chiasm in up to 5%. Am J Ophthalmol 1975; 80:975-990. Rare Seen Bilateral Orbital Chloroma Serkan Ünlü*, Mehtap Ilgar, Mehmet Akçiçek Malatya Education and Research Hospital, Radiology Department, Medical Doctor, Malatya-Turkey Casereport Open Access Journal of Case Reports: Open Access Received Date: December 24, 2019 Accepted Date: January 09, 2020 Published Date: January 11, 2020 There was soft tissue swelling around the mandible (Figure 2). years.3,4 Orbital chloromas present as proptosis, orbital tumour, dacrocystitis or orbital cellulitis, with leukemic or atypical cells seen on histopathology.5 The present work reports an unusual case of a two and half years old girl with Down syndrome with simultaneous presentation of cheek chloroma and Acute Radiology 1985;155: 167-170 2. Chloroma may precede the onset of leukemia or occur in bone marrow remission. CONCLUSIONS: Orbital chloroma can be easily misdiagnosed as other types of malignant orbital tumor in children. This tumor can be treated by chemotherapy and radiotherapy. CONCLUSIONS: Orbital chloroma can be easily misdiagnosed as other types of malignant orbital tumor in children. Chloroma may be regarded as an unusual form of myeloid leukemia in which a prominent feature is the deposition of tumour-like masses of myeloid cells in the skeleton (especially in the subperiosteal zones), lymph nodes and viscera. Granulocytic sarcoma is an uncommon manifestation of myelogenous leukemias in which focal masses of immature myeloid cells from the granulocytic lineage infiltrate bone and soft tissue. The diagnosis of orbital chloroma can be established by radiology and hematological examinations. High risk subgroup of acute This tumor can be treated by chemotherapy and radiotherapy.
