that is composed of immature myeloid cells. This tumor usually occurs in the course of, or rarely as a presenting sign of myelogenous leukemia (1), yet it can occur in patients with other myeloproliferative disorders or diseases such as polycythemia vera, myelofibrosis with myeloid metaplasia and hypereosinophilic syndrome (2). Myeloid sarcomas can involve any part of the body, but when they oc...
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 ...
Granulocytic sarcoma, a localized extramedullary tumor composed of myeloid blasts, develops in 2–6% of patients at the time of newly diagnosed acute myeloid leukemia (AML).1,2 Granulocytic sarcoma relapse following an allogeneic stem-cell transplant (SCT) is associated with marrow relapse in 20% of patients.2 Isolated granulocytic sarcoma following an allogeneic transplant is rare, seen in only...
Introduction: Myeloid sarcoma is an unusual extramedullary tumorous lesion consisting of immature cells of granulocytic series. Peritonsillar swelling as a manifestation of myeloid sarcoma is quite unique. The clinical diagnosis of this entity is difficult and fine needle aspiration cytology might be a useful alternative in centres with limited facility. We present such a case which clinically ...
We report here a case of inguinal sparganosis, initially regarded as myeloid sarcoma, diagnosed in a patient undergone allogeneic hematopoietic transplantation (HSCT). A 56-year-old male patient having myelodysplastic syndrome was treated with allogeneic HSCT after myeloablative conditioning regimen. At day 5 post-HSCT, the patient complained of a painless palpable mass on the left scrotum and ...
Myeloid sarcoma of the urinary bladder is a rare disorder. We report a 71-year-old man with hematuria who had a diffuse myeloid sarcoma of the bladder. He was also under follow-up for unclassified myeloproliferative/myelodysplastic disorder, diagnosed two months before. Abdominal ultrasonography and computed tomography findings were normal. Diagnostic cystoscopy revealed patchy areas of mucosal...
Myeloid sarcoma or granulocytic sarcoma (GS) is a rare disease with poor prognosis. It is characterized by the occurrence of tumor masses at an extra-medullary tissue. It is composed of myeloblastic cells and usually occurs in association with acute myeloid leukemia. Because of its nonspecific clinical and radiologic findings, its diagnosis might be challenging. It might be more commonly found ...
We report the rare occurrence of donor-derived myeloid sarcoma in two kidney transplant patients who received organs from a single deceased donor. There was no evidence of preexisting hematologic malignancy in the donor at the time of organ recovery. Both recipients developed leukemic involvement that appeared to be limited to the transplanted organ. Fluorescence in situ hybridization (FISH) an...
Myeloid Sarcoma (MS) is a tumor mass consisting of myeloblast with or without maturation occurring at an anatomical site other than the bone marrow. Incidence of MS ranges from 1-9% and is most commonly misdiagnosed as Non Hodgkins Lymphoma or poorly differentiated carcinoma. MS can occur in various sites but nasal cavity involvement is rare. Here we report acaseof MS presenting as nasal polyp ...
