[Hereditary benign telangiectasia: a rare form of primary telangiectasia with successful treatment with flash-lamp-pumped pulsed dye laser].

We report about multiple cutaneous telangiectases occurring over 3 generations. The pattern of inheritance, the morphology of the lesions, and the absence of hemorrhagic episodes are consistent with an unusual variant of primary telangiectasia described as hereditary benign telangiectasia. Differential diagnosis and pathogenesis of this rare type of telangiectasia is discussed. The lesions have been treated with the flashlamp-pumped pulsed dye laser. The lesions were completely removed by two treatments. Six months later, the patient had no recurrence of the telangiectases. Without producing scars or permanent pigmentary changes a very good cosmetic result has been achieved and stigmatisation and psychic burden of this patient has been relieved.
