Acute Myeloid Leukemia (AML) is the most common type of leukemia in children and is characterized by the rapid accumulation of immature white blood cells that are unable to perform their normal functions of fighting infection.
Signs and symptoms of AML in children may include fever, pallor, fatigue, weakness, bone pain, and bleeding. Additional findings may include an enlarged spleen and liver, petechiae, and anemia.
Physical examination of a child with AML may reveal hepatosplenomegaly, lymphadenopathy, and pallor. The most common laboratory findings include anemia, thrombocytopenia, and leukocytosis. Bone marrow aspiration is typically performed to confirm the diagnosis, and this may also reveal abnormal cells.
In some cases, imaging studies such as X-rays or CT scans may be used to evaluate for bone lesions or to aid in the staging of the disease. Additionally, immunophenotyping may be used to identify the specific type of AML and determine the best course of treatment.
AML in children can be aggressive and fatal if left untreated, so prompt diagnosis and treatment is essential. Treatment typically includes chemotherapy, which may be combined with radiation and/or stem cell transplantation, depending on the stage and type of leukemia.
