Abstract
Acute Undifferentiated Leukemia (AUL) does not express any markers specific for either lineage. Before categorizing leukemia as undifferentiated, it is necessary to perform immunophenotyping with a comprehensive panel of monoclonal antibodies. As AUL is the diagnosis of exclusion and is very rare, the morphology of leukemic cells in AUL is also not specific.\r\n
