Eosinophilic fasciitis is a disease manifest by thickening of the skin on the forearms. It is associated with eosinophilia so this is thought to be at least part of the mechanism of the disease.
Limb or trunk erythema and nonpitting edema and later by collagenous thickening of the subcutaneous fascia. Peau d'orange is the classic finding. Groove sign
Eosinophilia is a prominent laboratory finding in the early phase, although not always present in active early cases and less prominent in later stages [1]
No pharmaceutical treatment is available.
