Vaginal telangiectasias: unusual presentation of the Osler-Weber-Rendu syndrome.

Background: The Osler-Weber-Rendu syndrome (hereditary hemorrhagic telangiectasia) is an autosomal dominant disorder of blood vessels associated with mucocutaneous telangiectasis and arteriovenous malformations of internal organs.
Case: A 23-year-old woman was found on routine gynecologic examination to have asymptomatic vaginal telangiectasias, a previously unreported initial site of involvement in this syndrome.
Conclusion: The finding of asymptomatic vaginal telangiectasias on routine pelvic examination should alert the clinician to the possibility of the Osler-Weber-Rendu syndrome.
