title: Hyperleukocytosis with marked hypereosinophilia. Morphologic and cytochemical pathologic aspects of eosinophils. Eosinophilic leukaemia?
abstract: Excluding the most frequent pathologies that cause hypereosinophilia, we report a case of a patient with hyperleukocytosis and marked hypereosinophilia that showed morphological abnormalities in conjunction with cytochemical pathologic aspects. Physical examination, laboratory results and cytochemical abnormalities induced us, although a normal karyotype, to consider the possibility of eosinophilic leukaemia.
