Nevus flammeus

MUDr. Renata Faberová, PhD

Introduction

Inborn vascular tumor, several types

Clinical signs

pink or red wine colored patches
age: may be present at birth
do not regress, hypertrophy in higher age
part of several syndromes: Sturge-Weber (congenital, but nor familial angiomatosis affecting the skin of the face, leptomeninges and brain), Klippel-Trénaunay (nevus flammeus, congenital AV fistula and hypertrophy of the bones and soft tissues in affected area).

Histology

Flat angiomas consist of variably dilated capillaries. The lesion develops gradually. In early stages of development the histological picture is often inconspicuous: slightly increased number of histologically normal capillaries within the upper dermis is difficult to evaluate. Later variably dilated blood vessels appear. In adults there are usually many cavernous vascular spaces, vascular proliferations and fibrosis.
