Lymph Node - Erythrophagocytosis
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.
