These vascular birthmarks can occur anywhere on the body. When they occur on specific parts of the body (like in a nerve segment on the face) there are other places that we have to go look for it, just because we know that when port-wine stain happens over here, we’ve got to look inside. If a hemangioma happens all around the area, we’ve got to look inside. If a birthmark happens over here around the eye, again, we have to look inside. Specifically what we’re looking for is spread to either the eye, the optic nerve, or to the brain itself.
