Granulocytic sarcoma (GS) is a rare extramedullary manifestation of acute myeloid leukemia (AML). It may also represent blastic transformation of myelodysplastic syndromes or myeloproliferative neoplasms. Although usually seen in the context of advanced and poorly controlled disease, it may also present as the first manifestation of illness, without concurrent bone marrow or blood involvement. ...

Myeloid sarcoma is a tumor mass of immature myeloid or granulocytic cells that affects extramedullary anatomic sites, including uncommonly the oral cavity. A 24-year-old female was referred for evaluation of a fast growing painful gingival swelling lasting 2 weeks, associated with fever, fatigue, and cervical lymphadenopathy. Intraoral examination showed a bluish swelling on the right posterior...

granulocytic sarcoma (gs) is an unusual extramedullary tumor composed of immature granulocytic precursor cells. the intraoral occurrence of this tumor is extremely rare. here we report a case of gs with palatal swelling, gingival lesions in maxilla and mandible and aleukemic presentation in a 45 years old man.

Specifically, the diagnosis was chloroma, or infiltration by myeloid or granulocytic sarcoma. The patient was referred to the reference hospital for pediatric oncology, Hospital La Fe de Valencia, Spain, where a ...

Granulocytic sarcoma (in the past sometimes called chloroma because of the grossly greenish tinge of the tumoral tissue due to the presence of the enzyme myeloperoxidase) is a dramatic manifestation of acute myelogenous or myelomonocytic leukemia. A soft-tissue or an organ mass created by leukemic cells dominates the clinical presentation or develops later in the course of the disease after an ...

AIM To describe a case of primary granulocytic sarcoma. CASE DESCRIPTION A 43-year-old man presented with a painless testicular swelling. There was no previous history of malignancy or hematologic disease. Ultrasound and magnetic resonance imaging examination showed an intratesticular mass extending to the surrounding scrotal tissues including the epididymis. Inguinal radical orchiectomy was ...

In a previous publication it was shown that the red fluorescence of chioroma tissue was due to porphyrins readily extracted with ethyl acetate and acetic acid ; and that a dicarboxylic acid porphyrin, probably protoporphyrin, was chiefly responsible for the fluorescence (9). The present report is concerned with the isolation of crystalline protoporphyrin, the quantitative comparison of the amou...

A 26-year-old female was diagnosed with acute myeloid leukemia (AML-M2 subtype with normal cytogenetics) 2 years previously. She was induced with conventional 3 : 7 induction chemotherapy (daunorubicin; cytosine arabinoside) and consolidated with three high doses of cytosine arabinoside. After chemotherapy, the patient remained in remission for 1.5 years. A written informed consent was obtained...
