title: Chronic painless hematuria and urethral bleeding as the presenting manifestations of Osler-Weber-Rendu disease.
abstract: A case of a young man with profound iron deficiency anemia, chronic painless hematuria and urethral bleeding is presented. He had the typical cutaneous findings of Osler-Weber-Rendu disease (hereditary hemorrhagic telangiectasia). Appropriate urological studies demonstrated bladder and urethral telangiectases, with no other explanation for the bleeding. Osler-Weber-Rendu disease should be considered in the differential diagnosis of chronic painless hematuria.
