More than ten years have elapsed since the publication of the first edition of Tumors and Tumorlike Lesions of Bone and Joints in 1981. During this period significant progress has been made in diagnosis, and particularly in staging and treatment of bone tumors. In most centers, limb-sparing surgery has replaced the more radical ablative surgery, with or without preoperative chemotherapy. This became possible due to the introduction and increased application of newer high-quality imaging techniques (CT and MRI) and in particular the use of new cytomorphologic methods of diagnosis, especially immunohisto chemistry. These advances in diagnosis and treatment have been reflected by the publication of new editions of several important text books, since their authors - pathologists, orthopedic surgeons, and radiologists - felt the necessity of updating their works in recent years. However, in these publications different criteria of classification were adopted. The number of cases compiled at the Latin American Registry of Bone Pathology increased from 4913 primary bone tumors and more than 1100 tumorlike lesions at the time of publication of the first edition of this book, to 5274 bone tumors and 1665 tumorlike lesions by the end of December 1985, when I finished my work as head of the Registry and occupied the positions of Professor of Orthopedic Pathology at St. Louis University Medical Center and Distinguished Visiting Professor at Rush-Presbyterian-St. Luke's Medical Center in Chicago.

The discovery of a decaying body in the bush off a remote mountain road in Uganda's Western Province sparks off a complex, exacting investigation to find the killers, punctuated by flashes of intuition and some bizarre twists of fate. Dead End at Buffalo Corner's author, D.J. 'Jock' Macdonald, who headed up the investigation, was an Assistant Superintendent in the Colonial Police in charge of a 2000 square mile district straddling the equator in the shadow of the fabled Mountains of the Moon. Against the background of the disruption caused by a massive influx of refugees over his border, he brings vividly to life the people, places and events surrounding the brutal murder of Joseph Henri Mazy, a Belgian fleeing to Uganda from the growing violence engulfing the Congo's independence in 1960. Dead End at Buffalo Corner is a true police procedural, rich in detail, leading the reader through every step of the case, just as it happened. It is also a rare piece of social history, giving an equally accurate picture of a slice of a life - now gone for ever - in Uganda's final years as a British Protectorate.
