[Mixed vascular nevus. Report of 4 cases].

We describe four patients with a combined vascular nevus, consisting of telangiectatic and angiospastic parts, and give a review of 28 observations previously reported. In all of these cases the two different nevoid skin changes are situated directly adjacent to each. Therefore we consider this combination not to be an incidental finding but to represent a distinct entity. For this anomaly, we propose the designation "nevus vascularis mixtus".
