该病变低倍镜淋巴结结构破坏,可见模糊的结节状结构及弥漫的星空现象,中等偏大的细胞间散在少数小淋巴细胞,瘤细胞中等大、排列紧密、稍有多形性,可倾向伯基特淋巴瘤。儿童常见淋巴瘤有四种如DR zhouquan所述:伯基特淋巴瘤,淋母、HD及ALCL。就流行病学,Burkitt 淋巴瘤淋巴结受累多见于成人,而儿童受累者多见于结外。但是免疫缺陷患者的Burkitt常见于淋巴结和骨髓。但是流行病学提示概率性事件。
就HE形态学本例首先考虑伯基特淋巴瘤。需标记CD19、CD20、CD10、CD43、bcl-2,Ki-67、TDT、CD4、EMA等

Cannot see the lower power images very clearly. My impression: the architecture of lymph node is partially effaced with prominently interfollicular expansion of intermediate to large cells. Besides lymphoma/leukemia, reactive lymphadenopathy has to be ruled out, particularly EBV infection. Does this patient has splenomegaly? what do the lymphocytes in the peripheral blood look like? Any serology studies for EBV?

Thanks for the translation. Sorry I cannot type Chinese since I am in the office.
The tumor cells are kind of monotonous on higher power view, and it is not typical for reactive conditions, which would show a mixed population of cells with a maturational spectrum. so I favor lymphoma/leukemia although a reactive process has to be ruled out.

潘老师说:高背景下,瘤细胞呈单一的一种细胞,不是典型的反应性改变,反应性改变现实有成熟谱系的混合性的细胞成分。因次,我支持淋巴瘤/白血病,但是反应性过程也要排除。
