Ethylenediamine tetraacetic acid-associated leukoagglutination.
Three cases of ethylenediamine tetraacetic acid (EDTA)-induced leukoagglutination noted on peripheral blood films are reported. Two cases of EDTA-induced agglutination of benign lymphocytes, and one case of EDTA-induced mature neutrophil satellitosis about immature neutrophil were observed. EDTA-induced agglutination of malignant lymphoid cells has been reported in blood films from patients with malignant lymphoma and chronic lymphocytic leukemia. Our two cases are the first reported instances of EDTA-induced agglutination of benign lymphocytes. EDTA-induced agglutination of neutrophils is a well recognized, but uncommon event. This case was unusual because mature neutrophils were rosetted about a central immature granulocyte and no agglutination of mature neutrophils was noted.
