haemosiderosis
Definition
Noun: - Abnormal accumulation of hemosiderin: Haemosiderosis refers to a condition characterized by the excessive deposition of hemosiderin, an iron-storage complex, in tissues and organs. This is often a secondary finding associated with other diseases.
Usage
Haemosiderosis is a medical term used to describe a specific pathological state. It is typically identified through medical diagnosis and discussed in clinical contexts. - It is often a symptom or consequence of underlying conditions involving iron overload or increased red blood cell destruction. - The term is used interchangeably with hemosiderosis (American English spelling).
Examples
- The patient's liver biopsy revealed significant haemosiderosis, prompting further investigation for hemochromatosis.
- Pulmonary haemosiderosis can lead to respiratory symptoms due to iron deposition in the lungs.
- Chronic blood transfusions are a common cause of transfusion-related haemosiderosis.
Advanced Usage
- Idiopathic pulmonary haemosiderosis: A specific condition where iron accumulates in the lungs without a known underlying cause.
- Secondary haemosiderosis: This term emphasizes that the iron overload is a result of another primary disease process, such as thalassemia or chronic hemolytic anemia.

Word Origin and Notes
- Origin: From (relating to blood, from Greek ) + (relating to iron, from Greek ) + (a suffix indicating a pathological condition).
