A 70 year old man presents with weakness, low grade fever, and tightening and redness of the skin on his arms and legs. Laboratory tests show normal CK, ANA, RF but elevated CRP and ESR. A CBC shows hemoglobin of 11.2 g/dl and increased monocytes and eosinophils. The most likely diagnosis is eosinophilic fascitis.
