[Oedema and haemorrhagic diathesis in a 50-year-old woman with thyrotoxicosis].

We describe the case of a 50-year-old woman who presented with tachyarrhythmia, mild fever, peripheral oedema, ascites, epistaxis and gastrointestinal haemorrhage. Blood analysis revealed hyperthyroxinaemia. Analysis of thyroid-stimulating antibodies highlighted Graves' disease being the cause of the prevailing thyrotoxic crisis. Remarkable in this case of thyrotoxicosis is a liver affection without elevated transaminases but disturbed serum protein synthesis leading to hypalbuminaemic oedema and haemorrhagic complications. Thyrostatic treatment led to clinical response.
