虽然儿科血液病理学与成人的重叠，某些形式的白血病和淋巴瘤，以及影响骨髓和淋巴结的许多反应性疾病，对儿童来说是独一无二的。作为这个系列关注淋巴瘤的一部分，本文（1）详细介绍了自2017年世界卫生组织分类以来主要在儿童中发现的淋巴细胞白血病的新亚型，（2）讨论了儿科血液病理学中的独特概念，包括命名法的变化和部分淋巴瘤手术切缘的评估。
Although pediatric hematopathology overlaps with that of adults, certain forms of leukemia and lymphoma, and many types of reactive conditions affecting the bone marrow and lymph nodes, are unique to children. As part of this series focused on lymphomas, this article (1) details the novel subtypes of lymphoblastic leukemia seen primarily in children and described since the 2017 World Health Organization classification and (2) discusses unique concepts in pediatric hematopathology, including nomenclature changes and evaluation of surgical margins in selected lymphomas.
