Myeloid sarcoma (MS) as a rare localized solid tumor mass consists of myeloblasts or immature myeloid cells was found in an extramedullary site of a 4 year male child who was suffering with fever, abdominal distension since 4 months and swelling of legs from 1month . On examining pallor, bilateral cervical and inguinal lymphadenopathy, bilateral pitting pedal edema, Hepatosplenomegaly & ascites found. On investigation anemia with leukocytosis, thrombocytopenia was found. USG abdomen showed multiple non necrotic lymphnodes. Bone marrow aspiration suggestive of JMML, lymphnode biopsy showed myeloid sarcoma and was confirmed by immune histochemistry (IHC) markers LCA, KP-1(CD68), myeloperoxidase are positive.Immunophenotyping is useful in differentiating myeloid sarcoma from lymphoma and leukaemia. Child was treated with 3/7 regimen of cytoarabinoside, daunorubicin.
