  • n. An abnormal microscopic pigment, formed of granules of a complex of iron hydroxides, protein and polysaccharides, that forms in tissues of patients having an excess of iron

from the GNU version of the Collaborative International Dictionary of English

  • n. a granular yellowish-brown substance composed of protein and ferric oxide, resulting from the breakdown of hemoglobin; it has a higher iron content than ferritin, and its presence in body tissues or phagocytes can be a symptom of disturbed iron metabolism.

from The Century Dictionary and Cyclopedia

  • n. A dark pigment containing iron which has been found in extravasated blood and thrombi. It is undoubtedly derived from the blood-pigment.
