What is Siderosis and explain in detail?
Siderosis is the deposition of excess iron in body tissue. When used without qualification, it usually refers to an environmental disease of the lung, also known more specifically as pulmonary siderosis or Welders disease, which is a form of pneumoconiosis.
Pulmonary siderosis was first described in 1936 from X-ray images of the lungs of arc welders.The name siderosis comes from Ancient Greek word for iron, sídēr(os), and has an -osis suffix.

Signs and symptoms
Pulmonary siderosis doesnt usually cause harmful scar tissue formation within the lungs, which is why it said to be non-fibrotic condition, unlike asbestosis for example, and has also been called "benign pneumoconiosis".Mild to moderate scarring of the lungs has been found in unusual cases of pulmonary siderosis. These people have had persistent breathlessness, coughing and decreased lung function. However, people in occupations where they are exposed to iron (or rust) dust are usually also exposed to other forms of dust such as silica, which upon repeated inhalation is known to cause dangerous silicosis
