[Digestive hemorrhage disclosing an angiodysplasia and von Willebrand disease type 2].
The authors report a case of a 76-year-old man, with not past history of abnormal bleeding, who suffered an acute, recurrent, intestinal haemorrhage from extensive angiodysplasia of the colon. Intestinal bleeding and angiodysplasia were associated with a von Willebrand's disease. Genetic analysis showed a point mutation in arginine 611 of the mature von Willebrand's factor subunit (A1 loop) confirming a von Willebrand's disease type 2.
