The update of the 4th edition of the WHO classification for hematopoietic neoplasms introduces changes in the field of mature aggressive B‑cell lymphomas that are relevant to diagnostic pathologists. In daily practice, the question arises of which analysis should be performed when diagnosing the most common lymphoma entity, diffuse large B‑cell lymphoma. We discuss the importance of the cell of origin, the analysis of MYC translocations, and the delineation of the new WHO entities of high-grade B‑cell lymphomas.
世界卫生组织(WHO)造血系统肿瘤分类第4版的更新引入了成熟侵袭性B细胞淋巴瘤领域的一些变化,这些变化与诊断病理学家相关。在日常实践中,诊断最常见的淋巴瘤实体——弥漫性大B细胞淋巴瘤时,会出现应进行何种分析的问题。我们讨论了起源细胞的重要性、MYC易位的分析以及WHO高级别B细胞淋巴瘤新实体的界定。
