Haemosiderosis is a general term referring to the accumulation of haemosiderin, which particularly occurs in the reticuloendothelial system (RES) and does not cause organ damage.


Some causes include:

  • frequent transfusion 
    • mainly depositional siderosis in RES
    • if >40 units transfused: then may cause haemochromatosis (non-RES iron deposition)
  • high erythrogenic requirements (haemolytic anaemiamyelodysplasia)
    • mainly depositional siderosis in RES from transfusion
    • increased duodenal iron absorption may lead to haemochromatosis (non-RES iron deposition)
  • bantu siderosis: rare cause in Africa due to iron-laden locally brewed beer
