A case of acute myelogenous leukemia with an 8--21 translocation, missing Y, and additional karyotypic abnormalities.

A patient with acute myelogenous leukemia (AML) whose bone marrow cells had complicated chromosomal abnormalities, in addition to an 8--21 translocation and a missing Y chromosome, is reported. The complex additional abnormalities did not appear to have much influence on the clinical aspects of the disease, eg, cytology of the leukemic cells and the patient's response to chemotherapy, even though the patient did have a rectal tumor due to leukemic cell infiltration.
