title: Hereditary benign telangiectasia: first case in Iran.
abstract: A 14-year-old boy was referred to the Dermatology Clinic of the Medical University of Mashhad, Iran, with numerous cutaneous telangiectasias on the face, ears, lips, and back of the hands, with lesions in the temporal region being the first to appear (Figs 1-3). His mother stated that the lesions had been present for 10 years with an increase in the past 6 months. He had no history of bleeding from the nose, mouth, gastrointestinal tract, and other mucosal surfaces, and there was no sign of organ involvement. On inspection, no lesions were detected on the nasal mucosa, external ear, over the tympanic membrane, or mouth. The patient is one member of a family of six. His mother is healthy, but similar lesions were seen in his father, sister and one of his brothers with similar distributions. Lesions were also seen in his aunt and paternal grandmother, showing disease distribution in six members of this family from three generations. The oldest brother is 20 years of age and mentioned the onset of disease from the age of 10 years. The sister is 18 years of age and lesions started to appear 7 years ago; she claims that the lesions regress during her menstrual period. The youngest brother is 4 years of age and shows no sign of cutaneous lesions as yet. The parents are not consanguineous. Generalized telangiectasia with a predominant distribution on light-exposed skin, an autosomal dominant inheritance, and no sign of systemic or mucosal involvement and bleeding disorders indicates a diagnosis of hereditary benign telangiectasia. Our patient did not consent to biopsy.
