Histiocytic diseases arise from MAPK mutations in myeloid progenitors. Depending on whether the progenitor follows a dendritic cell or macrophage/monocyte lineage the final histology results in Langerhans cell histiocytosis, Rosai-Dorfman disease or Erdheim-Chester disease. Commentary on: Friedman et al. Mixed histiocytic neoplasms: A multicentre series revealing diverse somatic mutations and responses to targeted therapy. Br J Haematol 2024;205:127-137.
组织细胞疾病源于髓系前体细胞中 MAPK 的突变。根据前体细胞遵循树突状细胞还是巨噬细胞/单核细胞谱系,最终的组织学结果分别为朗格汉斯细胞组织细胞增生症、罗斯氏-多夫曼病或 Erdheim-Chester 病。述评:Friedman 等人。混合组织细胞肿瘤:揭示多种体细胞突变和对靶向治疗反应的多中心系列研究。《英国血液学杂志》2024;205:127-137。
