Living with Angioosteohypotrophic syndrome

A rare condition present from birth with blood vessel malformations that affect the soft tissues and bones of a limb.

Understanding Angioosteohypotrophic syndrome

Angioosteohypotrophic syndrome is a rare vascular anomaly syndrome present from birth, with vein or artery malformations that affect a limb.

The malformations lead to overgrowth of soft tissue and underdevelopment of bone. The affected limb is generally shortened, deformed, painful, and swollen, with weak bone and muscle. Usually one part, or several small parts, of a limb are affected. A larger area, including a whole limb, the shoulder area, and the armpit, has been reported.

Signs & symptoms

Symptoms vary. GARD's summary says they include:

  • Shortened, deformed limb
  • Pain in the limb
  • Swelling (edema)
  • Weak bone and muscle in the limb

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

    Your doctor may refer you to a specialist who knows rare conditions.

  3. Ask which tests can help

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