Hypereosinophilic Syndrome: A rare differential diagnosis for profound leucocytosis

@#A broad range of disorders are present with eosinophilia and these include infectious, allergic, rheumatic, neoplastic, endocrine and idiopathic disorders which range from benign to life-threatening illnesses. All these conditions create a heterogeneous list of clinical presentation that patients may display, thus creating a diagnostic challenge for clinicians. We present a patient with a broad range of clinical features and hematological counts that fit into the diagnosis of Hypereosinophilic Syndrome (HES). He was investigated reasonably to rule the various possible differentials and subsequently started on Prednisone therapy.
