Vascular causes of bleeding
Hereditary haemorrhagic telangiectasia
Rare autosomal dominant vascular disorder resulting in telangiectasia and recurrent bleeding.
Dilation of small arteries and capillaries result in characteristic small red spots that blanch on pressure (telangiectasia) in the skin and mucous membranes particularly the nose and gastrointestinal tract. Patients suffer from recurrent epistaxis and chronic gastrointestinal bleeds.
Patients are prone to chronic iron deficiency anaemia.
