This monograph on the "Ultrastructure of Human Sella Tumors" is in fact
a study of the correlations of clinical findings and morphology. It is a
timely and eagerly awaited publication because of the increasing
interest of the endocrinologist in pituitary disorders and of the neuro-
surgeon in the newest aspects of surgery on pituitary tumors, and also
because of the unsatisfactory but still widely accepted classification
into eosinophil, basophil and chromophobe pituitary adenomas. This old
classification has been mainly based on granule color as seen after
hematoxylin-eosin staining, but it does not, after extensive clinical
observations, reflect in many instances the type of clinical picture
observed. The author has brilliantly succeeded in demonstrating in a
convinc- ing way, by an extensive study of the relevant literature and
by his own histological work, that further insight into the biology of
the hypophysis and of the pituitary tumor can be obtained only by newer
methods of light microscopic staining, immuno-histochemistry and
electron microscopy combined with radio-immunological blood hormone
determination.
