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.
我们报告了一例具有组织细胞分化的急性髓系白血病(急性组织细胞白血病)的典型病例,患者为一名52岁有滤泡性淋巴瘤病史的女性。遗传学研究结果证实了淋巴瘤与白血病细胞之间存在克隆关系。据我们所知,这是滤泡性淋巴瘤向修饰碱基5-甲基胞嘧啶(M(5)c)样急性组织细胞白血病白血病转分化的首例报告,也是首例报道的转分化肿瘤的核型。
