摘要

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.
