Unilateral nevoid telangiectasia.

Unilateral nevoid telangiectasia is a cutaneous condition consisting of congenital or acquired patches of superficial telangiectases in a unilateral linear distribution. Unilateral nevoid telangiectasia has been associated with elevations of blood estrogen levels and/or an increased number of estrogen receptors in the involved skin. We present a hepatitis-B carrier case with unilateral nevoid telangiectasia on the face and the right side of the neck; she had normal blood estrogen and a normal number of estrogen receptors in the involved skin.
