Hemosiderin Hemosiderin collects throughout the body in hemochromatosis. Hemosiderin deposition in the liver is a common feature of hemochromatosis and is the cause of liver failure in the disease. Deposition in the pancreas leads to diabetes and in the skin leads to hyperpigmentation.

Is Hemosiderin Stain on the Lower Leg Life Threating ? Hemosiderin itself is not life threatening. It is caused by leaking of blood from vessels into the skin. May things can cause this. If you have leg swelling causing this you should have that evaluated. If it was caused by leg vein injections or trauma it is totally harmless to your health and is only a cosmetic problem.

Coagulation Leaking of blood through the endothelium initiates two processes: changes in platelets, and the exposure of subendothilial tissue factor to plasma Factor VII, which ultimately leads to fibrin formation. Platelets immediately form a plug at the site of injury; this is called primary hemostasis. Secondary hemostasis occurs simultaneously: Additional coagulation factors or clotting factors beyond Factor VII (listed below) respond in a complex cascade to form fibrin strands, which strengthen the platelet plug.

Von Willebrand disease Von Willebrand disease is caused by a deficiency of von Willebrand factor. Von Willebrand factor helps blood platelets clump together and stick to the blood vessel wall, which is necessary for normal blood clotting.

- It is unclear why some people with xeroderma pigmentosum develop neurological abnormalities and others do not. Inherited mutations in at least eight genes have been found to cause xeroderma pigmentosum. More than half of all cases in the United States result from mutations in the XPC, ERCC2, or POLH genes.he POLH gene also plays a role in protecting cells from UV-induced DNA damage, although it is not involved in NER; mutations in this gene cause the variant type of xeroderma pigmentosum. The major features of xeroderma pigmentosum result from a buildup of unrepaired DNA damage.

Angioedema Angioedema may be caused by an allergic reaction. During the reaction, histamine and other chemicals are released into the bloodstream. The body releases histamine when the immune system detects a foreign substance called an allergen. In most cases, the cause of angioedema is never found.

- : The histamine reaction in relation to the immune response (in both allergic reactions and immune reactions) serves two main functions: 1. It causes what is called “vasodilation.” Vasodilation occurs when the muscular walls that surround blood vessels are relaxed, causing the interior of the blood vessel to widen. 2.

Grass Founder in Horses Laminitis is triggered by a variety of causes, including repeated concussion on hard ground (road founder); grain overload; retained placenta; hormonal imbalance (Cushing’s disease or metabolic syndrome); certain drugs (corticosteroids); obesity; and lush grass.

Rapid Review Pathology Idiopathic pulmonary hemosiderosis (IPH) is a rare disease that causes recurrent diffuse alveolar hemorrhage with no detectable underlying disorder; it occurs mainly in children < 10 yr. It is thought to be due to a defect in the alveolar capillary endothelium, possibly due to autoimmune injury.

Hematospermia demystified Inflammation can be caused by irritation or trauma; stones or calcified deposits in the prostate, seminal vesicles, bladder, or urethra; and infections with viruses, bacteria, fungi, or parasites. Sexually transmitted diseases, such as herpes, gonorrhea, and chlamydia, have also been implicated in hematospermia.

Dermatology, April 2006 2006:32;400-404. Chondrodermatitis nodularis helicis (CNH) is a chronic, friction-induced inflammatory lesion classically occurring on the helix or antihelix and attributed to multiple factors, including repeated mechanical trauma, pressure, and chronic photodamage.

- Causes of heart disease. Coronary heart disease (CHD) is usually caused by a build-up of fatty deposits on the walls of the arteries around the heart (coronary arteries).The fatty deposits, called atheroma, are made up of cholesterol and other waste substances.The build-up of atheroma on the walls of the coronary arteries makes the arteries narrower, restricting the flow of blood to the heart muscle. This process is called atherosclerosis.DL cholesterol tends to build up on the walls of the coronary arteries, increasing your risk of heart disease. HDL, often referred to as good cholesterol, carries cholesterol away from the cells and back to the liver, where it's broken down or passed from the body as a waste product.

- Freebase(0.00 / 0 votes)Rate this definition: Hemosiderin. Hemosiderin or haemosiderin is an iron-storage complex. It is always found within cells and appears to be a complex of ferritin, denatured ferritin and other material. The iron within deposits of hemosiderin is very poorly available to supply iron when needed.

Causes of Abruptio Placentae List of causes of Abruptio Placentae. Following is a list of causes or underlying conditions (see also Misdiagnosis of underlying causes of Abruptio Placentae) that could possibly cause Abruptio Placentae includes: Abdominal trauma (see Abdominal symptoms) Ankylosis -- facial anomalies -- pulmonary hypoplasia syndrome - abruptio placentae.

- Vascular risk factors, especially hypertension, cause lipohyalinosis of the media and thickening of the vessel walls, which attributes to narrowing of the lumen of the small perforating arteries and arterioles nourishing the deep white matter [60].

Overview By Mayo Clinic Staff. The surface of your skin (epidermis) is made up of a thin, protective layer of cells that your body continuously sheds. Most epidermoid cysts form when these cells move deeper into your skin and multiply rather than slough off. The epidermal cells form the walls of the cyst and then secrete the protein keratin into the interior. The keratin is the thick, yellow substance that sometimes drains from the cyst. This abnormal growth of cells may be due to a damaged hair follicle or oil gland in your skin.

- NPDR can cause changes in the eye, including: 1  Microaneurysms: small bulges in blood vessels of the retina that often leak fluid. 2  Retinal hemorrhages: tiny spots of blood that leak into the retina.  Hard exudates: deposits of cholesterol or other fats from the blood that have leaked into the retina.

- If you don't get enough dietary calcium or enough exercise, bone calcium deposits can form in your tissues and organs; over time, bone calcium deposits can contribute to osteporosis, cancer, heart disease and other degenerative diseases. Calcium deposits can form when a bone is damaged or placed under stress. The body sends extra calcium minerals to the damaged area to help repair it. These minerals travel to the stressed or damaged bone through your blood stream.

- Leakage of fluid from the cyst (hyatid sand) causes eosinophilia. Rupture of a hydatid cysts as a consequence of trauma or surgery is very dangerous because it can cause anaphylactic shock, possible allergic reaction, and risk spreading hydatid sand which can give rise to new cysts throughout the body.

- Alpha-1 Antitrypsin related COPD is caused by a deficiency of the Alpha-1 Antitrypsin protein in the bloodstream. Without the Alpha-1 Antitrypsin protein, white blood cells begin to harm the lungs and lung deterioration occurs.

Hemosiderin The form of iron in ferritin is Iron(III) oxide-hydroxide. By complexing with ferritin, the iron is made water soluble. Several diseases result in deposition of Iron(III) oxide-hydroxide in tissues in an insoluble form. These deposits of iron are called hemosiderin. Although these deposits often cause no symptoms, they can lead to organ damage.

Amiodarone Amiodarone is sometimes responsible for epididymitis, a condition of the epididymis, and is normally associated with bacterial infections but which can also occur as a non-bacterial inflammatory condition. Amiodarone accumulates in the head of the organ and can cause unilateral or bilateral inflammation.
