C-MYC rearrangement has been listed as a new subcategory of B-cell acute lymphoblastic leukemia (B-ALL) in the latest International Consensus Classification (ICC), but B-cell lymphoblastic lymphoma (B-LBL) with C-MYC rearrangement is extremely rare and therefore is a novel finding worth reporting. In this study, we described a small number of pediatric cases of B-LBL with C-MYC rearrangement, which overlapped features of B-LBL and Burkitt lymphoma (BL), including highly aggressive clinical presentation, lymphoblasts with precursor B-cell phenotype and C-MYC rearrangement; the combination treatment of the mature B-NHL protocol and ALL-type protocol may be appropriate for this rare entity, and more studies are required to identify an adequate therapeutic strategy.
C-MYC重排在最新的国际共识分类（ICC）中已被列为B细胞急性淋巴细胞白血病（B-ALL）的一个新亚类，但伴有C-MYC重排的B细胞淋巴母细胞淋巴瘤（B-LBL）极为罕见，因此是一个值得报告的新发现。在本研究中，我们描述了少数伴有C-MYC重排的儿童B-LBL病例，其具有B-LBL和伯基特淋巴瘤（BL）的重叠特征，包括高度侵袭性的临床表现、具有前体B细胞表型的淋巴母细胞和C-MYC重排；成熟B-NHL方案和ALL型方案的联合治疗可能适用于这种罕见疾病，还需要更多研究来确定合适的治疗策略。
