[A cytochemical staining technique to detect esterase enzyme contained within monocytes and macrophages, which reacts strongly with the substrate alpha-naphthyl butyrate. Monoblastic [FAB M5a (without differentiation) or M5b (with differentiation)] and acute myelomonocytic (M4) leukemias have staining in blasts when the butyrate substrate is employed. Myeloid cells (either malignant or non-malignant) do not stain with nonspecific esterase techniques. ( NCI )]
