Idiopathic HES is identified after ruling out all other causes of eosinophilia. Poor prognosis is usually associated with cardiac involvement and malignant transformation of blood cells. We report a rare case of HES in an 8-year-old boy who presented with unilateral proptosis and torticollis. The patient responded well to corticosteroid therapy with reduction of proptosis and torticollis and normalization of serum eosinophil count. ER -
