Increased hematogones in an infant with bicytopenia and leucocytosis:a case report

Hematogones are the normal bone marrow constituents of bone marrow in children and their number decreases with age. As hematogones can resemble malignant lymphoblasts by their morphologic features and by expression of an immature B-cell phenotype, an accurate distinction of hematogone-rich lymphoid regeneration from leukemic lymphoblasts is critical for patient care. The increased number of hematogones had been reported in the bone marrow of children recovering from chemotherapy, aplastic conditions, other forms of bone marrow injury, infections like Cytomegalovirus, HIV and immune thrombocytopenia disorders. We describe here a case of one and half month old male infant with bicytopenia and leucocytosis associated with increased hematogones in the bone marrow due to an unknown probable viral infection.
