Hereditary benign telangiectasia (HBT) is a primary telangiectatic disorder, characterized by the presence of telangiectasias with different morphological features (lineal, punctiform, arborescent, reticulated, or in plaques) on the face, neck, upper trunk, and extremities.1 The mucosae are not affected, and there is no systemic involvement.1 Because it is an autosomal dominant disorder, lesions are usually present in several members of a single family.1
