概括
诊断非典型的淋巴细胞增殖需要仔细考虑患者病史,特别是关于CAR T细胞,BTK抑制剂和COVID-19疫苗接种等疗法. 这些干预可以导致具有挑战性的淋巴增殖性疾病 (LPDs),模仿恶性瘤.
科学领域:
- 血液病理学 血液病理学
- 在瘤学瘤学.
- 免疫学 免疫学 免疫学
背景情况:
- 将瘤与反应性淋巴增殖 (LPD) 区分开来是具有挑战性的,特别是当与治疗干预相关时.
- 2024年的研讨会重点关注在接受各种医疗治疗的患者中出现的非典型淋巴细胞扩散.
- 审查了44个病例,涵盖了与免疫抑制/免疫调节疗法,癌症治疗,药物反应和疫苗接种有关的广泛的LPD.
研究的目的:
- 讨论与治疗干预相关的淋巴细胞扩散的诊断挑战.
- 在现代医疗治疗的背景下,突出LPD诊断的关键特征.
- 强调临床信息的关键作用,包括药物史和疾病分布.
主要方法:
- 在2024年欧洲血液病理学协会/血液病理学协会研讨会上介绍的44个提交病例的审查.
- 聚焦第3届会议与治疗干预相关的非典型淋巴细胞扩散病例.
- 分析与免疫抑制疗法,固体瘤治疗,DRESS,CAR T细胞疗法,BTK抑制剂,达沙替尼和COVID-19疫苗接种相关的LPD.
主要成果:
- 与免疫抑制疗法相关的T细胞和NK细胞透物由于其克隆性或非克隆性而存在诊断困难.
- 药物反应与埃索诺菲利亚和系统性症状 (DRESS) 相关的淋巴腺病需要与T细胞淋巴瘤区分.
- 在CAR T细胞治疗后的LPD显示出不寻常的表型;BTK抑制剂 (BTKI) 的中断导致"伪里希特转变";达沙替尼诱导的花卵泡增生;与COVID-19疫苗接种相关的LPD显示出有障碍的免疫反应.
结论:
- 治疗干预相关的LPD的准确诊断需要全面的临床数据,包括药物史和疾病传播.
- 特定的LPD,如那些与DRESS,CAR T细胞疗法,BTKI,达沙替尼和COVID-19疫苗接种所见的,存在独特的诊断挑战.
- 了解这些实体对于适当的患者管理和避免误诊淋巴瘤至关重要.

Primary Lymphoid Organs

Primary lymphoid organs are pivotal in the formation, development, and maturation of lymphocytes, the white blood cells that serve as the backbone of our immune system. This crucial function underscores their fundamental role in maintaining our overall health and immunity. The two primary lymphoid organs of prime importance are the red bone marrow and the thymus.
The red bone marrow is a soft, spongy tissue nestled in the interior of long bones such as the humerus and femur. It is the site...

Secondary Lymphoid Organs

Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
