Lack of efficacy of topical timolol for cutaneous telangiectasias in patients with hereditary hemorrhagic telangiectasia: Results of a pilot study

To the Editor: Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant condition that results from mutations in several genes that lead to mucocutaneous telangiectasias and visceral arteriovenous malformations.1 Cutaneous telangiectasias do not usually occur until after puberty and the lesions increase in size and number with time. The lesions can be socially stigmatizing for patients and can bleed with minor trauma.
