Living with Gorham-Stout disease

A rare bone disorder in which bone is lost, often with abnormal blood vessel growth.

Understanding Gorham-Stout disease

Gorham-Stout disease is a rare bone disorder with bone loss (osteolysis), often with abnormal blood vessel growth.

Bone loss can happen in one bone or spread to soft tissue and nearby bones. It may affect any part of the skeleton, but most often the skull, collarbone, pelvis, ribs, spine, and jaw. Complications depend on which bones are affected. It can occur at any time in life.

Signs & symptoms

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

  • Bone pain
  • Bone loss (osteolysis)
  • Swelling
  • Increased risk of fracture
  • Chewing difficulties
  • Differences in the skull and facial bones

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.

  2. See a specialist

    Specialists who may be involved include autoimmune and inflammatory disease specialists, bone and joint specialists and genetic specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    Lymphangiomatosis & Gorham's Disease Alliance may keep lists of experts for this condition.
