<unk>  refers to elevated eosinophils in the peripheral blood.  It is important to remember that<unk>  is a symptom, not a disease.<unk>  can be a manifestation of a variety of different disease processes, including neoplastic, infectious, allergic, and idiopathic processes.
When the eosinophil count is markedly elevated and the patient has symptoms attributable to the eosinophils (and not explained by the underlying condition, if any), it is referred to as a hypereosinophilic syndrome.  Most patients with<unk>  do not have a hypereosinophilic syndrome.
