Hypereosinophilic syndrome is characterized by peripheral eosinophilia over 1,500 cell/mm3 and/or tissue eosinophilia, with dysfunction or damage to organ, once other causes were ruled out. This paper presents a case of hypereosinophilic syndrome (HS) which presented as lymphoblastic leukemia in a teenager. This is a 13 year old female, with B cell lymphoblastic leukemia at 9 years old, who received chemotherapy for 2 years achieving remission. ⋯ Six months after the onset of symptomatology there were generalized malaise, uncontrolled fever, gingival haemorrhage, asthenia and adynamia; a blood cell count reported blasts, and bone marrow smear confirmed the diagnosis of cell B lymphoblastic leukemia. The patient deteriorated rapidly showing signs of respiratory difficulty and acute pulmonary edema, therefore chemotherapy was started without response, and finally the patient died. There are several causes of HS, yet one of the least frequent presentations in childhood is the association with neoplasms.
