title: Cytochemical study of acute promyelocytic leukaemia.
abstract: Five cases of acute promyelocytic leukaemia (A.P.L.) are investigated for peroxidase, PAS, toluidine blue, astra blue, alpha-naphthyl esterase, double esterase incubation (naphthol-AS plus naphthol-AS-D chloroesterase), and cellular lysozyme activity. These cytochemical investigations may contribute further characterization of the morphologic type.
