Leukemias are the commonest childhood malignancy in West Bengal. This study was undertaken on 75 children at NRS Medical College, West Bengal to determine the distribution of signs and symptoms of leukemia and to identify unusual clinical features. After obtaining clinical history, physical examination, hematological and radiological investigations were performed. Acute lymphoblastic leukaemia (ALL, 72%) was the commonest followed by acute myeloid leukaemia (AML, 18.7%). Common symptoms and signs were fever (85.3%), pallor (64%), hepatomegaly (72%), splenomegaly (60%) and lymphadenopathy (50.7%). The uncommon signs and symptoms were abdominal pain (9.3%), joint pain (9.3%), hematemesis and malena (8%), diarrhea (5.3%), proptosis (2 cases), dysphagia, mediastinal mass and parotid swelling (1 case each). Uncommon clinical presentations lead to delay in diagnosis in some cases. Awareness of uncommon signs and symptoms of childhood leukemia together with laboratory tests may help in earlier diagnosis and proper management of the patients.

Tumor-associated macrophages (TAMs) are well accepted and the pathological role of macrophages in hematopoietic malignancies have been proposed. Hepatomegaly is frequently observed in T cell acute lymphoblastic leukemia (T-ALL) patients with poor prognosis. However, the role of leukemia-associated macrophages (LAMs) in hepatic microenvironment remains unclear. Here, the characteristics of hepatic LAMs (H-LAMs) were studied in Notch1 induced T-ALL model. Increase in proportion and absolute counts of H-LAMs was detected with infiltration of inflammatory cells. Furthermore, H-LAMs exhibited a more M1-like phenotype distinct from that of TAMs in hepatocellular carcinoma and LAMs from BM or spleen in leukemia. Moreover, H-LAMs expressed increased level of cytokines in charge of recruiting inflammatory cells, which contributed to pro-inflammatory hepatic microenvironment.
