ABSTRACT
Hereditary hemochromatosis is a frequent autosomal recessive iron storage disease in northern and western Europe. The classical clinical triad of liver cirrhosis, hyperpigmentation and diabetes is nowadays rare, most probably because of early recognition. The homozygous C282Y mutation in the HFE gene is responsible for most cases of hereditary hemochromatosis, although other much rarer mutations in other genes have been recently identified. Progressive iron overload not only causes liver cirrhosis but also triggers development of a characteristic arthropathy. Bony swelling with intermittent arthritis of the second and third metacarpophalangeal joints is typical as well as occurrence of chondrocalcinosis in wrists and knee joints. The therapy of choice is excess iron removal by phlebotomy. Treatment usually prevents or even reverses liver damage but does not alter the course of hemochromatosis arthropathy.
