100-YEAR-OLD HAEMATOLOGICA IMAGES: ACUTE HISTIOCYTEMIC SYNDROME OR BLASTIC PLASMOCYTOID DENDRITIC CELL NEOPLASM

Some authors were convinced that leukemias were neoplastic diseases, while others claimed them to be hyperplastic, reactive illnesses. Despite this uncertainty, the availability of new methods for staining blood cells and better microscopes stimulated many researchers to try to classify leukemias on a morphological basis.
