Eosinophilic fasciitis associated with autoimmune thyroiditis.

Eosinophilic fasciitis (EF) is scleroderma-like disease without Raynaud's phenomenon or visceral involvement. It is characterized by painful swelling of the extremities, accompanied by rapid weight gain, fever and myalgia. The acute state of disease is associated with significant peripheral blood eosinophilia, an elevated erythrocyte sedimentation rate and hypergammaglobulinemia. EF is also frequently associated with hematological abnormalities, including malignant lymphoproliferative diseases, but rarely associated with autoimmune thyroiditis. In the present study we report a case of eosinophilic fasciitis associated with autoimmune thyroiditis.
