Abstract
THE ability of synovial cells to phagocytose small particulate matter has long been accepted for haemosiderin and can be readily demonstrated in such cells in ordinary histological sections from cases of chronic haemarthrosis1. Only now is the full phagocytic power of the synovial cell beginning to be recognized. Thus, it has been shown that not only a variety of small particulate substances like ferritin2, gold3, thorotrast4, iron dextran6 and carbon6 when injected into the joint space are readily taken up by these cells but that entire erythrocytes7 can also be ingested in this fashion (Fig. 1). This is indeed remarkable because usually erythrocytes are fragmented before phagocytosis by macrophages8.
