The areas involved dictate the signs that may be found on physical examination. Obvious physical findings of OWRD (ie, HHT) are limited to those in the skin and mucous membranes. However, physical findings may also be present in many other organs. Common sites of involvement include the following:

  • Skin
  • Nasal and oral mucosa
  • CNS
  • Respiratory system
  • GI tract
  • Liver
  • Cardiovascular system
  • Eyes
