Granulocytic sarcomas (chloromas) are rare extra-medullary tumors arising from primitive granulocytic cells. The term "chloroma" is derived from the Greek word chloros (green), and it refers to the frequently greenish color of the tumor, which is due to the presence and oxidation of the myeloperoxidase enzyme. These tumors can arise de novo or can be associated with other myeloid disorders, suc...
Myeloid sarcoma is a tumor which consists of myeloblasts or immature myeloid cells. This tumor presents in the lymphoid organs, bone, skin, soft tissue, various mucosae and organs, and the central nervous system. Granulocytic sarcoma, an extramedullary acute myeloid leukemia, is also referred to as chloroma (GS) because of its greenish surface color. Granulocytic sarcoma is rare and difficult t...
Orbital or subconjunctival infiltration occurs frequently in acute and chronic lymphatic leukaemia, but only rarely in myelogenous leukaemia (Chatterjee and Sen, I 960). Chloroma, an atypical form of myeloblastic leukaemia, often manifests itself as a localized mass in the orbital periosteum, and the proptosis produced in such cases may be the first sign of the disease (Goodman and Iverson, I94...
Granulocytic sarcoma also known as extramedullary myeloid sarcoma or chloroma is an uncommon manifestation of leukemia and presents as a deposit of leukemic cells outside the bone marrow. We report a case of a twenty-five-year-old pregnant woman who presented with progressive dysphagia and recurrent postprandial vomiting. Upper GI endoscopy had shown large flat laterally spread nodular lesions ...
Fifteen cases (3.1%) of localized myeloblastic tumors occurring among 478 patients with acute granulocytic leukemia (AG 1) and chronic granulocytic leukemia (CGL) are described. The majority of tumors were discovered at autopsy. Numerous cases of chloroma associated with AG L have been reported; however, in this series, the incidence of myeloblastic tumors in CGL was twice as high. The importan...
The “dural tail sign” was described by Wilms and colleagues as a thin, tapering rim of dural enhancement, in continuity with a convexity meningioma on gadopentetate dimeglumine– enhanced magnetic resonance (MR) (1). Goldsher and associates subsequently, in 1990, demonstrated the dural tail sign in 60% of their series of meningiomas and concluded that its presence, associated with an extraaxial ...
BACKGROUND Granulocytic sarcoma (GS) is a form of acute myeloid leukemia (AML), also known as extramedullary myeloid tumor or chloroma. It forms a solid malignant tumor consisting of myelocytes or granulocytes and is typically located in bone while occurrence in other parts of the body is rare. CASE PRESENTATION We reported a 40-year-old male patient who had jaundice, highly elevated bilirubi...
