What morphologic investigations can contribute to the understanding of physiological and pathological processes is magnificently demonstrated in this king-sized volume, the main portion of which is an atlas of lymph node cytology. The introductory text presents the techniques employed for electron microscopy and brief case histories of the patients whose lymph node biopsies were used for this study. In a detailed outline of normal lymph node cytology, findings obtained with light microscopy and electron microscopy are correlated with each other and with functional aspects. This forms the background for a lucid discussion of the ultrastructure of cells in malignant lymphomas. While the authors take a stand on some controversial aspects of nomenclature and interpretation, they commendably refrain from introducing any new terminology.
The main portion of the monograph consists of 100 excellently reproduced plates, mostly electron micrographs, provided with informative legends and markings. They follow the same sequence as the
