Abstract

We report an instructive case of acute myeloid leukemia with histiocytic differentiation (acute histiocytic leukemia) arising in a patient, a 52-year-old woman with a history of follicular lymphoma. The results of genetic studies proved a clonal relationship between the lymphoma and the leukemic cells. To our knowledge, this is the first report of leukemic transdifferentiation of follicular lymphoma into modified base 5-methylcytosine (M(5)c)-like acute histiocytic leukemia and the first reported karyotype on a transdifferentiated neoplasm.
