ICD11: -

Lateral nevus, flammeus nevus, portwine stain, vinosus nevus.

Congenital or early-stage malformation of capillaries and postcapillary venules located laterally of the midline.

There has been no vascular innervation, which reduces the vascular tone, resulting in vasodilatation.

  • Red wine coloured, purple, sharply defined maculae. The reddening disappears due to the compression of the glass spatula pressure.
  • Associated malformations 
    • Pphacomatosis pigmentovascularis
    • Congenital Angiodysplasia Syndromes

In the case of periorbital localization, an ophthalmological examination (glaucoma, retinal damage) is indicated.

Subepidermal capillary dilatation.
