    Correct Answer: A

    Solution :

    : Haematochromatosis (hemochromatosis) is a condition showing staining of tissues with blood pigment due to abnormal and excessive deposition of iron from haemoglobin or excessive ingestion of iron. This syndrome is characterized by pigmentation of the skin, pancreatic damage with diabetes (bronze diabetes), cirrhosis of the liver, a high incidence of hepatic carcinoma, and gonadal .atrophy. Hemochromatosis may be primary or secondary. Primary hemochromatosis is an. autosomal recessive disease. Secondary hemochromatosis occurs when the iron-regulating system is overwhelmed by excess iron loads due to chronic destruction of red blood cells, liver disease, or chronically increased iron intake. Haemosiderosis is a condition characterized by deposition of haemosiderin, especially in liver and spleen, bone marrow and other tissue. Hemoptysis is the expectoration of blood arising from the oral cavity, larynx, trachea, bronchi or lungs. Haematoma is a collection of blood, generally the result of haemorrhage. It exist as bruises (ecchymoses), but can also develop in organ.
