Abstract

Purpose: Cytogenetic abnormalities have been proven to be among the most valuable prognostic indicators in leukemia, allowing the stratification of patients in risk groups. We describe a patient diagnosed as AML-M5, with myeloid sarcoma and tetrasomy 8 as the sole chromosomal abnormality. We confirm that the presence of polysomy 8 in myeloid lineage malignancies is associated with a distinct clinical entity comprising of myelornonocytic/monocytic lineage involvement, poor prognosis and high incidence of myeloid sarcoma. In aim to obtain a detailed description of this clinical entity, literature of polysomy 8 cases has been reviewed.
