Hypereosinophilia is generally described as having an absolute eosinophil count of more than 500/mm3 in peripheral blood. 500-1500/mm3 is classified as mild, 1500-5000/mm3 as moderate, 5000/mm3 and above as severe eosinophilia. The causes of eosinophilia in children are similar to those seen in adults and it is separated into two groups as primary and secondary eosinophilia. Primary eosinophilia includes some genetic conditions such as hereditary eosinophilic syndrome. Secondary eosinophilia develops as a reaction to a certain cause. Among possible causes of secondary eosinophilia, we can list infections, atopy, medications, gastrointestinal diseases, lymphocytic diseases, and immunodeficiencies. In this paper, we discuss the differential diagnosis of hypereosinophilia in a 3-month-old girl presenting with generalized seborrheic dermatitis, hypereosinophilia, CMV viremia and pneumonia.
