Living with Painful orbital and systemic neurofibromas-marfanoid habitus syndrome

A rare condition with painful, non-cancerous nerve tumors around the eyes and body and a tall, slim build.

Understanding Painful orbital and systemic neurofibromas-marfanoid habitus syndrome

Painful orbital and systemic neurofibromas-marfanoid habitus syndrome is a rare condition with painful, benign nerve tumors.

Benign (not cancer) nerve sheath tumors called plexiform neurofibromas grow in the eye sockets, skull, large spinal nerves, and moist body linings. People also have a tall, slim, Marfan-like build, enlarged nerves in the eyes, and certain facial features. GARD lists the onset as the teenage years.

Signs & symptoms

Symptoms vary from person to person. GARD describes these features:

  • Painful nerve tumors (neurofibromas)
  • Tall, slim, Marfan-like build
  • Enlarged nerves in the cornea of the eye
  • Drooping eyelid (ptosis)
  • Bulging eyes (proptosis)
  • Lumps in the lips and under the tongue

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

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

  2. See a specialist
