Hereditary benign telangiectasia: two case reports.

We present two cases of hereditary benign telangiectasia (HBT) in which the genetic findings are compatible with an autosomal dominant hypothesis. The lesions persisted indefinitely for many years without effect on the general health of the patients. The term hereditary benign telangiectasia distinguishes the disorder from the more serious hereditary hemorrhagic telangiectasia (Rendu-Osler-Weber).
