[Life threatening epistaxis due to plasma coagulation disorder as a partial manifestation of gluten sensitive enteropathy].

We report on a 73 years old female patient receiving a recurrent epistaxis due to a severe plasmatic malcoagulation. In spite of since twenty years remaining diarrhoea coeliac disease has been diagnosed but now causative of the malcoagulation. On the occasion of this report clinical, current pathogenetical, immunological and pathohistological aspects of coeliac disease have been described. At last we agree to the differential diagnosis of anaemia in coeliac disease and in this connection to the metabolism of vitamin K too.
