We report a unique case of childhood acute leukemia. The leukemia blasts had lymphoblastoid appearance and expressed CD33, CD13, CD34, CD4, CD7, and CD56. The morphology and immunophenotype were most consistent with myeloid/natural killer precursor acute leukemia. The blasts had a complex karyotype, including two chromosomal aberrations, der(5)t(4;5)(q31;q31.3) and t(14;17)(q32;q23), not previously described in childhood acute leukemia. The patient achieved morphological remission following myeloid-based leukemia therapy.
我们报告了一例独特的儿童急性白血病病例。白血病原始细胞具有淋巴母细胞样外观，并表达CD33、CD13、CD34、CD4、CD7和CD56。其形态学和免疫表型与髓系/自然杀伤前体急性白血病最为相符。原始细胞具有复杂的核型，包括两种染色体畸变，即der(5)t(4;5)(q31;q31.3)和t(14;17)(q32;q23)，这在儿童急性白血病中此前未曾描述过。该患者在接受基于髓系的白血病治疗后实现了形态学缓解。
