Granulocytic sarcomas (GS) is a rare extramedullary tumor composed of myeloid progenitor cells. Granulocytic sarcoma, also known as extramedullary myeloid tumor, is a localized infiltrate of immature granulocytes in an extramedullary site that superficially resembles sarcoma clinically. Makni S, Bahri I, Ayadi L, et al: [Colonic granulocytic sarcoma: A case report]. Oral granulocytic sarcoma presents as a localized soft tissue mass, although less frequently intraosseous presentation has been reported. Bones, lymph nodes, and skin are the favored sites of involvement. Granulocytic sarcoma also called myeloid sarcoma is an extramedullary tumor of immature granulocytic cells. This tumor was first described by Burns in 1811. Her peripheral leukocyte count was (118 × 109/L), with 98% immature blood cells. Myeloid sarcoma may develop during the course of a hematologic disorder but is seen to precede the disorder in 35% of cases. 1994).It is most commonly associated with acute myeloid leukemia (AML), in which 2.5–8% of patients will develop GS before, during or after the onset of systemic leukemia (Pui et al. The Diagnosis: Granulocytic Sarcoma. Finally, infections, including fungal invasion of the skin, can be responsible for rashes, as can the vast array of antimicrobials that are administered to leukemia patients.

Granulocytic sarcoma is an uncommon tumor composed of granulocytic precursor cells. Clusters of these cells stained intensely positive for myeloperoxidase (Figure 1B insert), which confirmed the diagnosis of granulocytic sarcoma. A biopsy of the mass showed massive infiltration of … It can occur anywhere in the body but is most commonly found in bone, soft tissue, lymph nodes and skin. Myeloid sarcoma (MS), also known as granulocytic sarcoma (GS) or chloroma (named for the greenish hue attributed to the pigment of myeloperoxidase [MPO]), is a rare solid tumor with a predilection for the orbit.

KEYWORDS: granulocytic sarcoma, acute nonlymphoblastic leukemia, prognosis, chemotherapy. Granulocytic sarcoma of the cheek occurred in one patient 10 months before the diagnosis of acute myelocytic leukemia could be made. It should therefore be considered as a differential diagnosis of any atypical cellular infiltrate. An 89-year-old woman with refractory anemia presented with a painful neck mass that measured 5 cm × 3 cm ([Figure 1][1]A). Neutrophilic and eosinophilic granulocytic sarcomas have been documented in swine (Kadota et al. This presentation details the authors’ experience with 61 biopsy-proven granulocytic sarcomas.

Granulocytic sarcoma (GS) is a neoplasm consisting of myeloid precursors in an extramedullary site. These tumors often develop during the course of, or as a presenting sign of, acute myeloid leukemia (AML) ( 2 ). In patients with the latter disorder, the lesion por- tends a poor prognosis and im- pending transformation to the acute phase of disease. The skin contained focal infiltrates of pleomorphic mononuclear cells that were identified as granulocytes by demonstration of intracytoplasmic naphthol-ASD-chloroacetate esterase and lysozyme.

It may be found in any location throughout the body; however, intraoral occurrence is extremely rare. In 1853, King initially called it chloroma, because typical forms have a green color caused by high levels of myeloperoxidase in these immature cells. The term “chloroma” was originally used in response to the green color of the tumor due to the presence of MPO in the tumor cells. A tumor-like collection of AML cells under the skin or other parts of the body is called a chloroma, granulocytic sarcoma, or myeloid sarcoma. “Chronic” in the chronic granulocytic leukemia (CGL) is a term that indicates a type of cancer that slowly progresses as compared to acute types of cancer.
