Living with Port-wine stain with oculocutaneous melanosis

A rare skin condition from birth with a widespread port-wine birthmark and a pigment birthmark, sometimes with eye or brain involvement.

Understanding Port-wine stain with oculocutaneous melanosis

Port-wine stain with oculocutaneous melanosis is a rare skin disease with both a widespread port-wine stain and a pigmented birthmark.

It is present from birth. It can come with other skin birthmarks, and sometimes with problems outside the skin, most often involving the brain, eyes or bones and muscles. Several subtypes are described based on their features.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Port-wine stain (a flat red or purple birthmark)
  • Darker patches of skin
  • Lighter patches of skin
  • Glaucoma (raised eye pressure)
  • Seizures
  • Lower bone density

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  3. Ask which tests can help
