A CYTOLOGICAL AND HISTOLOGICAL STUDY OF ACUTE PREMYELOCYTIC LEUKAEMIA

Among the acute leukaemias of the granulocytic group, acute premyelocytic leukaemia is distinguished by the severity of its haemorrhages, the frequency of hypofibrinaemia, a rapidly fatal course, and an unusual cellular hyperplasia. Myelograms show an increased proportion (average 80%) of characteristic cells of large diameter, with numerous azurophil granules. The infiltration of other organs is inconstant.
