In addition to the port wine stain and pigmentary lesions, other skin lesions are not uncommon, such as:
Nevus of Ota
Nevus of Ito
Around half of people with PPV have systemic involvement (i.e., other body systems are affected). Eye conditions such as ocular melanosis (also called ocular melanocytosis) is common. Ocular melanosis refers to a blue-gray pigmentation in the 'white of the eye' or sclerae. This condition often occurs along with nevus of Ota and may affect one or both eyes. The complications of nevus of Ota are glaucoma and melanoma, as a result people with nevus of Ota require careful examination and follow-up by an opthamologist. Other eye conditions reported in PPV include iris hamartomas, iris mammillations, and iris nodules.
Some individuals with PPV also have Sturge-Weber syndrome or Klippel-Trenaunay syndrome. Signs and symptoms of Sturge-Weber syndrome include a large port-wine stain facial birthmark, blood vessel abnormalities in the brain called leptomeningeal angiomas, as well as glaucoma, seizures, muscle weakness, paralysis, developmental delay, and intellectual disability. Klippel-Trenaunay syndrome is characterized by a port-wine stain, abnormal overgrowth of soft tissues and bones, and vein malformations.
