Fibro Adipose Vascular Anomaly

Also known as: FAVA.

What is a fibro adipose vascular anomaly?

FAVA is a rare but painful lump (mass) that develops in a muscle (usually involving a limb) where the muscle tissue is replaced by tough fibrous (scar-like) tissue, fatty tissue and abnormal blood vessels. Diagnosis is often delayed till late childhood or adolescence.


What causes fibro adipose vascular anomaly?

FAVA is not an inherited disorder; however in some children a spontaneous genetic mutation appears to be the cause, while in others no cause may be found.


What are the symptoms of fibro adipose vascular anomaly?

Common symptoms include pain (often severe) in the affected limb, difficulty or loss of movement and some enlargement of an affected limb, with visible veins on the skin over the mass.


What are fibro adipose vascular anomaly care options?

There are a number of treatments available, depending on position, size and symptoms. Common ones include pain management, physical therapy, surgery to remove the tissue, or cryotherapy, embolization, and immunosuppressant medication.

What is the Personalized Medicine Biobank?
The Nicklaus Children's Hospital biobank and tissue repository is an essential resource for personalized medicine research efforts, enabling the study of both health and disease over time. The Biobank collects samples and health information from volunteers, regardless of health history. Once a participant becomes part of the Biobank, he or she contributes to ongoing health research. We partner with Sanford Health, a national leader on specimen storage, management and integration with participant health information.
January Patient of the Month: Layla
When Layla was 5, she came to Nicklaus Children's Hospital with a severe case of scoliosis. To help straighten her spine, Layla spent time in halo gravity traction. While her mom returned home to Gainesville for work and school, the nurses at Nicklaus Children's took care of Layla, acting as substitute mothers and making sure she was well cared for.
