We describe a father and two daughters with hereditary benign telangiectasia. Both girls had numerous telangiectases distributed over the upper limbs, trunk, face, and vermilion border of the lips. The father displayed less extensive lesions and had been unaware of their presence. All three patients were in good health; the younger daughter had a past history of mild recurrent epistaxis. Differentiation of this benign entity from other primary telangiectatic disorders is discussed.
