The kidneys are responsible for many key bodily functions, but their primary role as a filter of toxins makes them extremely susceptible to disease. Often these diseases can only be diagnosed through a renal biopsy, a complicated procedure requiring ancillary immunologic and molecular diagnostic techniques. This book covers all methods used by renal pathologists to diagnose a wide range of kidney diseases. Unlike most literature on renal pathology, this book is situated on the midpoint between encyclopedic and superficial coverage, written for the signing-out pathologist. While focusing on tumors and transplantation rejection, a full spectrum of infectious, inflammatory, and congenital disorders is covered in both pediatric and adult populations and is analyzed not only by light microscopy but by each applicable diagnostic modality available. The text is illustrated with more than 1,000 photomicrographs and diagrams, including a CD-ROM of all images.
