Is haemosiderin always haemoglobin derived?

    Hello everyone,

    Haemosiderin definition says that it is a pigment that occurs when there is a local or systemic excess of iron. Does that mean excess iron deposition can cause haemosiderin pigment, I mean you don't alway need macrophages to eat Hb and make it, just iron is enough. Thanks :smile:

    Just to clarify are you asking if excess iron is the cause of haemosiderin synthesis? I don't find your post clear to understand.
