Eosinophilic Fasciitis Overview
Learn About Eosinophilic Fasciitis
Eosinophilic fasciitis (EF) is a syndrome in which tissue under the skin and over the muscle, called fascia, becomes swollen, inflamed and thick. The skin on the arms, legs, neck, abdomen or feet can swell quickly. The condition is very rare.
EF may look similar to scleroderma, but is not related. Unlike scleroderma, in EF, the fingers are not involved.
Shulman syndrome
The cause of EF is unknown. Rare cases have occurred after taking L-tryptophan supplements. In people with this condition, white blood cells, called eosinophils, build up in the muscles and tissues. Eosinophils are linked to allergic reactions. The syndrome is more common in people ages 30 to 60.
Symptoms may include:
- Tenderness and swelling of the skin on the arms, legs, or sometimes the joints (most often on both sides of the body)
- Arthritis
- Carpal tunnel syndrome
- Muscle pain
- Thickened skin that looks puckered
Corticosteroids and other immune-suppressing medicines are used to relieve symptoms. These medicines are more effective when started early in the disease. Nonsteroidal anti-inflammatory drugs (NSAIDs) may also help reduce symptoms.

Arthritis is a rare complication of EF. Some people may develop serious blood disorders or blood-related cancers, such as aplastic anemia or leukemia. The outlook is much worse if blood diseases occur.
Contact your health care provider if you have symptoms of this disorder.
