Abstract
The most common childhood malignancy is acute leukemia. Approximately 15- 20% of it, is Acute myeloid leukemia (AML). The general symptoms of this malignancy include fatigue, weakness, fever, paleness and bleeding disorders. There are two methods of classifying for AML: The French-American-British (FAB) and the World Health Organization (WHO) classification.The M4 eos subtype, also called myelomonocytic leukemia, is one subtype of AML with eosinophilia. The most common cytogenetic variations in this leukemia include inv (16) (p13q22) or the variant t (16; 16) (p13; q22). In this report, we present the first AML-M4 eos case with a new translocation that has not yet been reported.
