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.
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 ...
Histopathology of the liver, showing Kupffer cells with significant hemosiderin deposition (shown next to a hepatocyte with lipofuscin pigment, which is a common normal finding). H&E stain. Prussian blue iron staining, highlighting the hemosiderin pigment as blue. This finding indicates mesenchymal iron overload (within Kupffer cells and/or ...
Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
Early in his career, Amron, a dermatologic surgeon, began focusing his practice on tumescent liposuction, a type of surgery where patients do not undergo general anesthesia for the procedure, so ...
[5] [8] [14] Later stages show significant hemosiderin deposition in the stroma, fibrosis, and a collapsed appearance of the arterial lumen. [8] [14] Clinical differential diagnoses include infantile hemangioma, melanocytic lesions, tufted angioma, insect bite, Kaposi sarcoma, erythema multiforme, and dermatofibroma, depending on the stage of ...
Some complications are common for all types of leg associated surgery, while some are specific to popliteal bypass surgery. Complications include but not limited to the following: In the study of 6,007 people carried out popliteal bypass surgery, the overall rate of morbidity and mortality was 36.8% and 2.3% respectively within 30 days post ...
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. [1] Siderophages are not specific of heart failure.
