Case for diagnosis. Hereditary Hemorrhagic Telangiectasia

The Osler-Weber-Rendu syndrome or Hereditary Hemorrhagic Telangiectasia (HHT) is a systemic fibrovascular dysplasia characterized by defects in the elastic and vascular walls of blood vessels, making them varicose and prone to disruptions. Lesions occur in different organs and can lead to hemorrhage in the lungs, digestive tract and brain. We describe the case of a patient with cutaneous manifestations and severe impairment of the digestive tract. It is important for the dermatologist to recognize this syndrome, since the cutaneous lesions may play a key role in diagnosis.
