诊断要点:当淋巴结内出现噬红细胞现象时,应当对其进行诊断并分级。
病变描述
淋巴结内的噬红细胞现象(erythrophagocytosis)是指窦内巨噬细胞吞噬外渗的、衰老的和/或受损的红细胞(Figure 1、Figure 2,箭头)。噬红细胞现象在正常条件下不发生,最常与淋巴结出血、充血、窦性红细胞增多症以及自身免疫性和其他免疫病理状态相关。
诊断与分级建议(NTP 共识)

Comment:
Erythrophagocytosis in lymph nodes consists of macrophages within sinuses that phagocytize extravasated, old, and/or damaged erythrocytes ( Figure 1 and Figure 2 , arrows). Erythrophagocytosis does not occur under normal conditions and is most often associated with lymph node hemorrhage, congestion, sinus erythrocytosis, and autoimmune and other immunopathologic conditions.
Recommendation:
When erythrophagocytosis is present within lymph nodes, it should be diagnosed and graded.
