Hereditary hemorrhagic telangiectasia (HHT) most commonly manifests with nasal mucosal
telangiectasias, and vascular endothelial growth factor (VEGF) plays a significant role in this
angiodysplasia. We describe a patient with HHT with epistaxis recalcitrant to several
endonasal procedures and six cycles of intravenous bevacizumab, for which he was
dependent on iron infusions and packed red blood cells transfusions. He then started

Hereditary hemorrhagic telangiectasia (HHT) most commonly manifests with nasal mucosal telangiectasias, and vascular endothelial growth factor (VEGF) plays a significant role in this angiodysplasia. We describe a patient with HHT with epistaxis recalcitrant to several endonasal procedures and six cycles of intravenous bevacizumab, for which he was dependent on iron infusions and packed red blood cells transfusions. He then started pazopanib at 100 mg with dramatic improvements in epistaxis and normalization of hemoglobin and iron levels, without replenishment needs for 12 months. This is the first report on the efficacy of pazopanib with high selectivity for abrogating VEGF receptor‐2 signaling in HHT, and needs to be explored further. Laryngoscope, 128:2234–2236, 2018
