Choriodecidual Haemosiderin Staining
Choriodecidual haemosiderin staining is defined as the presence of iron, preferably confirmed by using histochemical stains, in the amniochorial membranes or the basal plate. Placental haemosiderosis is a wider term which includes also the villous haemosiderosis. Haemosiderin staining can be graded as mild, moderate or severe, based on the extent and density of haemosiderin deposition. It is a typical association of placental chronic abruption but it can be also seen in asymptomatic patients, particularly when iron stain is used. In this latter situation, its significance and other associations remain to be determined.
