The human urinary bladder is subject to a unique and extraordinarily diverse array of congenital, inflammatory, metaplastic, and neoplastic abnormalities. This book provides contemporary, comprehensive, and evidence-based practice information for pathologists, urologists, oncologists, and other medical professionals. A full spectrum of pathologic conditions that afflict the bladder and urothelium are described and lavishly illustrated. With its emphasis on diagnostic criteria and differential diagnoses, this book is of particular value to practicing pathologists--assisting in the pathologist's recognition, understanding, and accurate interpretation of the light microscopic findings in bladder specimens. With emphasis on the scientific validation of current diagnostic methods and their direct application in clinical practice, a cutting-edge resource that not only offers comprehensive research and clinical information for practicing surgical pathologists, urologists, oncologists, and their clinical colleagues, but also captures a genuine sense of excitement about recent advances in this vital, ever-evolving field.
