Acute lymphoid leukemia in Adult
Diagnosis usually requires the presence of over 20% lymphoblasts in the peripheral blood and/or the presence of bone marrow or tissue infiltrate of immature cells with confirmation of lymphoid lineage by flow cytometry and/or cytochemistry.
ALL / LBL is the most common cancer in children (mostly younger than 6 years and accounting for a quarter of all childhood malignancies) and is also seen in adults (usually older than 60 years). Children may present with unexplained fevers, pallor, hepatosplenomegaly, lymphadenopathy, and/or bleeding and easy bruising. The cause of ALL / LBL is unknown, but it has been associated with ionizing radiation as well as certain genetic abnormalities.
