Hemosiderin image of a kidney viewed under a microscope. The brown areas represent hemosiderin. Hemosiderin or haemosiderin is an iron-storage complex that is composed of partially digested ferritin and lysosomes. The breakdown of heme gives rise to biliverdin and iron. [1] [2] The body then traps the released iron and stores it as hemosiderin ...
Hemosiderin hyperpigmentation is pigmentation due to deposits of hemosiderin, and occurs in purpura, haemochromatosis, hemorrhagic diseases, and stasis dermatitis.
Hemosiderin deposition in the lungs is often seen after diffuse alveolar hemorrhage, which occurs in diseases such as Goodpasture's syndrome, granulomatosis with polyangiitis, and idiopathic pulmonary hemosiderosis. Mitral stenosis can also lead to pulmonary hemosiderosis. Hemosiderin collects throughout the body in hemochromatosis.
"The chronic heat can cause vascular changes, as well as collagen degradation," adds Aguilar. "Repeated heat exposure damages superficial blood vessels leading to hemosiderin deposition ...
Siderophages (brown spots) in an endometriotic focus. A siderophage is a hemosiderin-containing macrophage. Heart failure cells are siderophages generated in the alveoli of the lungs of people with left heart failure or chronic pulmonary edema, when the high pulmonary blood pressure causes red blood cells to pass through the vascular wall.

Brown induration is fibrosis and hemosiderin pigmentation of the lungs due to long standing pulmonary congestion (chronic passive congestion). Occurs with mitral stenosis and left sided heart failure .
Schamberg's disease, (also known as "progressive pigmentary dermatosis of Schamberg", [1] "purpura pigmentosa progressiva" (PPP), [1] and "Schamberg's purpura" [1]) is a chronic discoloration of the skin found in people of all ages, usually only affecting the feet, legs or thighs or a combination.
Fleischer rings are pigmented rings in the peripheral cornea, resulting from iron deposition [2] in basal epithelial cells, in the form of hemosiderin. [3] They are usually yellowish to dark-brown, and may be complete or broken. [4] The rings are best seen using the slit lamp under cobalt blue filter. [4] They are named for Bruno Fleischer. [5]
