Morphology and distribution of nasal telangiectasia in HHT-patients with epistaxis.

Background: Epistaxis in hereditary hemorrhagic telangiectasia (HHT; Rendu-Osler-Weber syndrome) is a frequent symptom that may be caused by a multitude of different genetic and epigenetic phenomena. This investigation analyzes the distribution of nasal telangiectasia in 21 patients with HHT.

Methods: The patients were examined for endonasal telangiectasia by videoendoscopy with rigid endoscopes; in addition, the anterior portion of the nose was examined under the operating microscope.

Mucocutaneous telangiectases of the head and neck in individuals with hereditary hemorrhagic telangiectasia -- analysis of distribution and symptoms.

Telangiectases are a diagnostic clue of hereditary hemorrhagic telangiectasia (HHT, Rendu-Osler-Weber disease), but they are not specific to HHT. The characteristic features of telangiectases were studied in a group of 70 individuals with this disorder. The files, including photo and video documentation of these patients, were reviewed with regard to mucocutaneous vascular lesions.

The value of screening for multiple arterio-venous malformations in hereditary hemorrhagic telangiectasia: a diagnostic study.

Occult visceral arterio-venous malformations (AVMs) may be a constant threat to patients suffering from hereditary hemorrhagic telangiectasia (HHT), also known as Rendu-Osler-Weber syndrome (M. ROW). HHT patients predominantly become symptomatic through chronic, recurrent epistaxis, a symptom that can alert physicians at an early stage of the disease.
