title: Cytology of cardiac myxomas: presence of Ulex europaeus agglutinin-I (UEA-I) lectin by immunoperoxidase staining.
abstract: Cytological findings are presented of seven cases of cardiac myxomas. Avidin-biotin-peroxidase complex (ABC) method was employed to demonstrate Ulex europaeus agglutinin-I (UEA-I) lectin in imprint smears as well as in paraffin-embedded tissue sections in cardiac myxomas. The cytology was characterized by tumor cells with polyhedral or stellate and mucinous background with lymphocytes, neutrophils, and hemosiderin-laden macrophages. In smears as well as tissue sections, UEA-I lectin was detected throughout the cytoplasm of myxoma cells. This study established the applicability of the immunoperoxidase staining for cardiac myxoma as an aid in cytopathological diagnosis.
