A pigmented octogenarian [PDF]

open access: yesAge and Ageing, 2010
An 81-year-old woman presented with cachexia, malaise, deranged liver function tests (LFTs), hepatomegaly and hyperpigmentation. Hereditary haemochromatosis (HH) was ultimately diagnosed on genetic testing. Haemochromatosis is a difficult diagnosis in older people because not only are the symptoms protean and occur commonly in other geriatric ...
