title: Two cases of hereditary benign telangiectasia in Turkey: sporadic occurrence with punctate telangiectasias surrounded by anemic halos.
abstract: Hereditary benign telangiectasia (HBT) is a very uncommon, genetically inherited, benign skin disorder, identified by widespread cutaneous telangiectasias. Herein, we present two sporadic cases of HBT that were admitted to the dermatology clinic for multiple punctate telangiectasias surrounded by anemic halos, favoring sun-exposed areas. These cases had no mucosal or visceral involvement and exhibited no family history of the disorder. The phenotypes of HBT are clinically and genetically heterogeneous. More clinical experience and genetic analyses are needed to understand the basis for the genetic heterogeneity and to determine genotype-phenotype correlations. We aimed to emphasize the hereditary and clinical heterogeneity of HBT by presenting two cases of HBT with punctate telangiectasias surrounded by anemic halos, with a sporadic occurrence.
