Living with Acquired partial lipodystrophy

A rare condition, also called Barraquer-Simons syndrome, with loss of fat from the face, neck, shoulders, arms, and chest.

Understanding Acquired partial lipodystrophy

Acquired partial lipodystrophy, also called Barraquer-Simons syndrome, is marked by loss of fat from the upper body.

Fat is lost from the face, neck, shoulders, arms, forearms, chest, and belly. Onset usually begins in childhood after a viral illness, and it affects females more often than males. After puberty, women may gain fat in the hips and legs. Around 1 in 5 people develop a kidney condition, usually more than 10 years after onset. Autoimmune disorders can also occur. GARD lists onset as childhood to adulthood.

Signs & symptoms

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

  • Loss of fat in certain areas (lipoatrophy)
  • Autoimmune problems
  • Low complement C3 level
  • Muscle tissue disease
  • Hearing impairment
  • Premature aged appearance of the face

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 hormone specialists and skin, hair, and nail 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

    Foundation of the National Lipid Association may keep lists of experts for this condition.
