Six families in which a few members, in three generations, were affected with medial telangiectatic nevus (salmon patch, stork bite, angel's kiss) on the forehead, glabella, upper eyelids, upper lip, nose, and nuchal and occipital areas are presented. This is a mild variant of lateral telangiectatic nevus (nevus flammeus, port-wine stain) that disappears in about 50 percent of patients during the first years of life. In one family, lateral telangiectatic nevus (nevus flammeus, port-wine stain) and superficial (strawberry) hemangioma coexisted with medial telangiectatic nevus. This paper discusses the familial incidence of medial telangiectatic nevus and a new modality of treatment. Moreover, the paper presents a classification of vascular malformations and proposes a new terminology.
