title: Partial deficiency of eosinophil peroxidase.
abstract: A new case of partial eosinophil peroxidase deficiency is reported. It was identified and elaborated using an automated flow-cytochemical analyzer. The findings were confirmed by conventional cytochemistry on blood smears: decreased staining intensity in peroxidase and Sudan Black staining. These results are in agreement with other reports on this extremely rare peroxidase deficiency, which probably is of no clinical relevance.
