Bone and Radiostrontium

florid cases bulk large in the literature, because their spectacular qualities make them attractive subjects for reporting." Equally commendable is the discussion of the nature and genesis of adamantinoma of the limb bones, a highly controversial topic; Jaffe presents all current theories fairly and deflates them all equitably. In an age so conscious of radiation and its effects upon tissues, the reviewer cannot resist singling out for mention the chapter on radiation injury and postradiation sarcoma of bones. The text is balanced and sane, leaving plenty of room for filling out the framework with new data when such becomes available. The illustrations of radiation osteitis are "classical"-in the sense that the classical picture is the best illustration as opposed to what one usually gets to see. One of the features that will appeal to both clinicians and pathologists alike is the section on differential diagnosis which accompanies the text dealing with specific lesions. The paragraphs are not long, but they are the distillate of much practical experience and good medical judgment. The bibliographies following each chapter are well selected and will guide the reader to both classical descriptions of lesions and good contemporary reviews and significant case reports. One misses, perhaps, the reference to Antoni's original description of type A and type B tissue in neurilemmonas, but this is a minor point. There is certainly no effort to avoid relevant references merely because they are in a foreign tongue. Each reviewer is entitled to cavil at a certain point. One queries whether the chondromyxoid fibroma and the desmoplastic fibroma are quite so strictly separable entities as Jaffe states. Could they not be different phases of a common process? Are they completely unrelated to the non-ossifying fibroma? Speculation outruns data at this point. One also can speculate with the author regarding the route taken by the metastases from the giantcell tumor of the upper end of the femur appearing 2Y2 years later in the prepuce (See Fig. 1 B). We can only hope, in conclusion, that Dr. Jaffe, having dealt with neoplastic bone disease so successfully, will now devote his efforts to summarizing his experiences with metabolic and degenerative diseases of bone.
